Core body, or thoracic temperatures of around 24 degrees Celsius are necessary for flight. Therefore, the black swallowtail will regulate thoracic temperatures by behaviorally changing their abdomen position, wing position, orientation to the sun, perching duration, and perching height. In lower temperatures, butterflies will raise their abdomens above flattened wings, and will perch relatively close to the ground. In higher temperatures, butterflies will lower their abdomens in the shade of their wings.
Like the previously described Southeast Asian Pygoplatys individuals, the females actually carry young nymphs around on their abdomens. As the nymphs grow older, they eventually separate from their mothers, lose their bright colors, and become more solitary prior to molting into adults. Species which exhibit this behavior often have significantly flattened and expanded abdomens. Of the Australian oncomerines, the bronze orange bug (Musgraveia sulciventris) is the only species unequivocally documented to lack maternal brooding behavior.
Features distinguishing lophogastrids from the mysids include the absence of statocysts in their uropods, and the presence of well-developed biramous pleopods on their abdomens. Their molecular characters also differ.
The abdomens of the sexes differ in that the males appear to have "pointed" abdomens, which are actually their copulatory organs, while females have more rounded abdomens. Newly hatched nymphs are translucent, light in color at first, becoming browner as they moult and approach maturity. A Cimex nymph of any age that has just consumed a blood meal has a bright red, translucent abdomen, fading to brown over the next several hours, and to opaque black within two days as the insect digests its meal. Cimex may be mistaken for other insects, such as booklice, small cockroaches, or carpet beetles; however, when warm and active, their movements are more ant-like, and like most other true bugs, they emit a characteristic disagreeable odor when crushed.
Newly emerged male S. albicincta on its exuvia Members of this genus are medium-sized dragonflies with dark bodies and a metallic green lustre. The eyes are brilliant green, and many species have dull to bright yellow markings on the thorax and/or abdomen. The abdomens of males are distinctive, with the first two segments bulbous-shaped, the third constricted, and the rest of the abdomen club-shaped with a straight ending. Females have abdomens with straighter sides.
The abdomens of males are brown with lighter markings and with brown-black hairs lying on the surface, and a short band of white hairs. The legs of both sexes are dark brown, with light markings in the femora (the sections of the legs nearest the body). All species of the genus Portia have elastic abdomens, so that those of both sexes can become almost spherical when well fed, and females' can stretch as much when producing eggs.
Female G. westringi have hard, shell-like abdomens that are about three times as wide (about 13 millimeters, without spines) as long (4 millimeters) and are flared upward at each end like a pair of wings. Their abdomens bear three pairs of spines. The front (anterior) pair are short, about 1 millimeter long, black, and point slightly forward. The middle (median) pair are black at the base and red for much of their length, with black tips.
They are known for their habit of raising their long abdomens and opening their jaws, like a threatened scorpion. In this defense posture, they secrete an irritating substance, with a very unpleasant smell.
They approach workers that land nearby and oviposit on the host by curling their abdomens. The workers repeatedly brush their abdomens afterwards, suggesting that they were aware that an attack occurred. The overall effect of this parasitism is usually fatal. Older workers are more likely to be parasitized. Because of this, as long as the number of parasites is minimal, the overall cost to the colony is not large, since these workers have already contributed substantially to the colony’s welfare.

Queens are about in length and in width, which is larger than workers that are typically about in length and in width. Both queens and workers have black hair that covers their heads, much of their legs, and the bottom of their abdomens. They also both have completely yellow hair on the majority of their abdomens, except for a small section near the area closest to the rear end of the bee.
Latrodectus hasselti, the redback spider The widow spiders (genus Latrodectus), such as the black widow, redback spider, and katipō are spiders that carry a neurotoxic venom which can cause a set of symptoms known as Latrodectism. Widow spiders are large, shiny house spiders with relatively spindly legs and deep, globular abdomens. Mature females have dark and shiny abdomens with one or several red spots, either above and/or below. The spots may take the form of an hourglass, or two triangles, point-to-point.
Females can be distinguished from males by their wider abdomens and smaller second pereiopods. The genital openings are found on the body segments containing the fifth pereiopods and the third pereiopods in males and females, respectively.
In this form, the abdomen contains reddish brown markings on the first few segments on the males, while female abdomens have pale red markings. Male and certain females also possess small white spots on the abdomen.
Also, they may evolve shield over their genital openings to prevent intromission. Females of some species of water striders have evolved protection from forceful insemination, such as abdominal spines and downward-bent abdomens to make it harder for males to mate. In response, however, males have counter evolved, also changing the shape of their abdomens to those that would facilitate forceful mating. The male waterfowl (Aves: Anatidae) evolution of a phallus to forcefully copulate with females has led to counteradaptations in females in the form of vaginal structures called dead end sacs and clockwise coils.
Trogus species have a body length of . Their abdomens resemble a row of rectangular blocks due to each abdominal segment having thick edges and deep cuts. An autapomorphy of Trogus is a concave apical edge of the clypeus.

In some species, the larvae cluster together, reducing their chances of being killed, and in some cases form together with their heads pointing outwards or tap their abdomens up and down. Some adults bear black and yellow markings that mimic wasps.
Both males and females have a body length of around , males having smaller abdomens. Like other species in the genus, the basic body colour is dull brown or dark grey. Markings vary, with some specimens having orange and white hairs.
Males have less subcutaneous fat in their faces due to the effects of testosterone; testosterone also reduces fat by aiding fast metabolism. Males generally deposit fat around waists and abdomens (producing an "apple shape") due to the lack of estrogen.

The abdomens of females are pale yellow with black markings and the upper sides have scattered white and orange-brown hairs. Males' abdomens yellow-orange to orange-brown with blackish mottling, and on the upper sides are black and light orange hairs, and nine white tufts. Those of females' are pale yellow and have black markings with scattered white and orange-brown hairs on the upper side, but no tufts.
The order Trigonotarbida is a group of extinct arachnids whose fossil record extends from the late Silurian to the early Permian (Pridoli to Asselian). These animals are known from several localities in Europe and North America, as well as a single record from Argentina. Trigonotarbids can be envisaged as spider-like arachnids, but without silk-producing spinnerets. They ranged in size from a few millimetres to a few centimetres in body length and had segmented abdomens, with the tergites across the backs of the animals' abdomens, which were characteristically divided into three or five separate plates.
The head of this species is reddish brown with one pair of oval, black compound eyes, and sucking/piercing mouthparts. This species can reach a length of 6 to 8 mm (0.6 cm to 0.8 cm). Female B. carambolae can be differentiated from male B. carambolae by observation of longer abdomens, and an ovipositor on the posterior end of the abdominal segments, where as males have shorter abdomens and a more rounded tip of their abdominal segments. Compared to other members of the B. dorsalis complex, B. carambolae have shorter male reproductive organs, known as aedeagi, and broader costal bands on their wings.

Most species are small in size and have narrow abdomens. Their nymphs are bottom dwellers, and resist droughts by burying themselves very deeply. Synthemistid dragonflies frequently prefer marshy areas, as well as fast- flowing streams. The family Synthemistidae is sometimes called Synthemidae.
The females of this species are 40% larger than males when fully mature. They have pear-shaped bodies, as their abdomens fill with eggs as they reach a mating stage. Another distinction is the females have a more pronounced genital region, called an ovipositor.
Dolichopteridae, which lived in the Silurian and Devonian periods, had outer surfaces that were either smooth with pustules and semilunar scales. Their compound eyes were arcuate and located anteriorly on the prosoma (head). Their abdomens had epimers (lateral projections). The telson, (tail) was lanceolate.
Orthetrum villosovittatum is a medium-sized dragonfly with a wingspan of 60–85 mm. Mature males have dark greyish to greenish-brown thoraxes and red abdomens, with the abdomen constricted at segment four. Young males have an amber and black colouring. Females are ochre-coloured.
Breeding takes place in the summer and females have been seen brooding eggs under their abdomens in the months of July and August. After hatching, the larvae pass through several planktonic larval stages before settling on the seabed and undergoing metamorphosis into the adult form.
The abdomens of M. quadrifasaciata queens swell with ovarian development, making older queens larger than workers which is typical of most social bees. Queens vary slightly in their coloring, having brown eyes and brown hair compared to the black eyes and hair of worker bees.

In 1979 Konopka worked with Alfred Handler to discover the nature behind pacemaker signalling by transplanting brains of donor flies into abdomens of arrhythmic host flies. They found that circadian rhythms in host flies were restored with the period of the donor; for example, short period (perS) adult brains implanted into the abdomens of arrhythmic (per01) hosts could confer a short period rhythm on the activity of some hosts for at least 4 cycles. Since the transplanted brains were unable to create new neuronal connections to locomotor activity centers, Konopka and Handler concluded that pacemaker signalling for locomotion must be humoral and not neuronal.
These tracheal gills are multifunctional and key to many biological processes. No dense tufts or branching gills are found on their thoraces or abdomens, unlike other Plecoptera families. The larvae also possess broad, chisel-like mandibles. Adults have two ocelli in addition to its two compound eyes.
Also, females tend to be larger than the males. Between the genera there are multiple distinction between the sexes. For example, males in Argulus and Chonopeltis possess secondary sexual modifications on legs 2-4. The sexes both have their own sexual reproductive organs on their abdomens.
The virus is concentrated in the heads and abdomens of infected adult bees with significantly reduced titers in the thorax. The genome is detectable by reverse transcriptase-polymerase chain reaction in the head, thorax, abdomen and wings of infected bees. Only the legs are devoid of virus.
They have spindly legs covered in light coloured hairs which are strongly modified for digging with their teeth, spines and/or bristles. Their abdomens have 6 ventrites and the hind wing has a spring mechanism which can fold. As larvae, the grub forms as a C-shape.
Adult females are 47 to 60 millimeters (2-2.5 inches) in length while adult males are usually about 54 millimeters (2.2 inches) in length. First instar nymphs are 7-12 millimeters (.028-.047 inches) in length. When the nymphs eat more, their abdomens get much longer.

The bodies of these spiders are rather compressed in the vertical direction, which allows them to hide themselves under the loosened bark of trees and in other tight places. They have a prominent pattern on their abdomens which may make them more difficult to distinguish on mottled surfaces.
As workers forage, their abdomens become clear and distended, similar to replete workers. When they return to the nest, they regurgitate their collected nectar into replete workers for storage. March through November is the typical foraging time for M. mexicanus. The summer months are when most nectar is collected.
Libellula incesta, the slaty skimmer, is a dragonfly of the skimmer family, native to eastern United States and southern Ontario, Quebec, and New Brunswick. Adults are long. Mature males are dark blue with black heads. Females and juveniles have brown abdomens with a darker stripe down their backs.
They are small, hairy moths, with reduced or absent mouthparts and fringed wings. They often perch with their abdomens sticking out at 90° from their thoraces and wings. North American moths are mostly cryptic browns, sometimes marked with white or green, but the hag moth mimics bees.Wagner, D.L. (2005).
However, when they flee, they swim backward quickly by curling and uncurling their abdomens. A speed of has been recorded. This is known as the caridoid escape reaction. Symbiotic animals of the genus Symbion, the only member of the phylum Cycliophora, live exclusively on lobster gills and mouthparts.
Neoptera is a classification group that includes most orders of the winged insects, specifically those that can flex their wings over their abdomens. This is in contrast with the more basal orders of winged insects (the "Palaeoptera" assemblage), which are unable to flex their wings in this way.
Their abdomens are long and thin. Most are colored blue and or green, with black and occasionally yellow. Their large, hemispherical, compound eyes touch in the midline and nearly cover their heads. They have an extremely good sight, and are voracious insect predators, using their sharp, biting mouthparts.
The animals show very little sexual dimorphism; males are only slightly larger than females. They have a uniform, steely-grey coat on their backs and fur with a yellowish tinge on their abdomens. As the coat weathers, it becomes brownish. When born, the pups weigh and are about long.
Kannis are medium-sized dogs, with straight top lines and tucked-up abdomens. Height at the withers is and weight ranges from . They have straight heads, strong jaws, golden eyes and black noses. The ears are medium-sized and flat, and can be erect, dropping or semi dropping.
Workers are polymorphic, the largest reaching about 10 mm long. They can produce formic acid in their abdomens and eject it 12 cm in the air when threatened.Dr Timothy Batchelor Msu.edu - Southern red wood ant Formica rufa The only function of males is to mate in flight with queens.
Their breast is red in color, and turns purple towards their abdomen and thighs. They have a deep orange beak with yellow or orange eyes. Juvenile Stephen's lorikeets have green underparts with purple or red marks on their throats and abdomens. Their tail tends to be a dark green.
The butterfly usually has three ocelli on the underside of their hindwing, although these may not appear during the dry season.Subtribe Ypthima The larvae feed on Poaceae grasses. Larvae have also been reared on Ehrharta erecta.Swaziland National Trust Commission Females are usually more sedentary than males, with stouter abdomens.
Cimex have segmented abdomens with microscopic hairs that give them a banded appearance. Adults grow to long. The different species are very similar in morphology and can only be separated by microscopic examination. Sexual dimorphism occurs in C. lectularius, with the females larger in size than the males on average.
Males typically have a slender abdomen, darker anterior appendages and the embolus is spade shaped and bent basally. Males use their dark anterior appendages to signal females during elaborate courtship displays. Females are generally larger with relatively larger abdomens, more uniform coloration among the legs and pedipalps are blunt ended.
The middle and hind legs are very long and have prominent spines. Adults have a characteristic resting posture with the body and fully outstretched wings forming a T shape, the forewing covering the hindwing, and the hind legs raised and extended parallel with the body. Males have longer, thinner abdomens.
Jewish women invented new ways of cooking in order to make food and supplies last longer. Tuberculosis and other diseases were widespread due to malnutrition. The physical attributes of malnutrition in the Łódź Ghetto led to sunken eyes, swollen abdomens and aged appearances while also stunting the growth of Ghetto children.
Mezium americanum Mezium americanum, the American spider beetle or black spider beetle,Mezium americanum (Laporte). Entomology. Commonwealth Scientific and Industrial Research Organisation. is a species of beetle in the subfamily Ptininae, the spider beetles. These are sometimes mistaken for spiders or mites because of their rounded abdomens and long legs.
It is one of the few species in order Odonata in which males are larger than females,Fincke, "Population Ecology", 394. with abdomens up to 10 cm (4 in.) long and wingspans of up to 19 cm (7.5 in.)Groeneveld et al.—the greatest wingspan of all odonates.Lewington and McGavin, 23.
Occasionally the abdomens are nearly white in color. The cephalothorax is yellow to burnt-orange with a central dark line and dark lines down either side. The femora and patellae are orange. The other leg segments are yellow, becoming brown at the distal ends, as are all of the legs of the males.
As with most or all species of mantis, Phyllocrania paradoxa is sexually dimorphic, with females being larger than males. Females have six abdominal segments. Males are shorter, narrower, and have eight- segmented abdomens. At the 5th instar and above males are thinner than females and have smaller appendages (lateral of the abdomen).
If rhinoceros beetles are disturbed, some can release very loud, hissing squeaks. The hissing squeaks are created by rubbing their abdomens against the ends of their wing covers. Rhinoceros beetles are relatively resilient; a healthy adult male can live up to 2–3 years. The females rarely live long after they mate.
They are relatively large compared to other sweat bees.Richards, M. H. (2001). Nesting biology and social organization of Halictus sexcinctus (Fabricius) in southern Greece. Canadian Journal of Zoology, 79(12), 2210–2220. doi:10.1139/cjz-79-12-2210 They are 14–16 mm in length, and have white felt bands on their abdomens.
Stylonurids, which lived from the Ordovician to Lower Permian periods, were small to very large forms with scales developing into tubercules and knobs. The prosoma (head) exhibited variable shape, with arcuate compound eyes located subcentrally, or anteriorly. Their abdomens were slender. Their walking legs were long and powerful, sometimes characterized by spines.
It is found in the hill forests of Sri Lanka. Subspecies intermedius is found in Southeast Asia in Sumatra, Borneo, and parts of the Malay Peninsula. The brownish grey wash on the breast of females is darker, contrasting with the white of the abdomens. The back is darker brown than in other subspecies.
Dead bugs which died before they could release all their chemicals can be distinguished from the 'clean' bugs by their blackened abdomens after boiling. These are also rejected. The remaining bugs are then dried under the sun. In cases where the bugs were collected dead, another method is used to remove the chemicals.
These ants have a two-segmented petiole (a petiole and postpetiole) connecting their abdomen to the thorax. They have 10 segments in their antennae, which end in large segmented clubs. Thief ants possess small stingers on their oblong abdomens. Worker ants have large jaws for carrying food, usually other ants' brood, back to the colony.
These flies are covered in black or pale (white or golden) hairs, and are themselves either black or metallic green or blue. The scutellum is with apical calcars and wing vein R4+5 with an appendix. They have simple legs and abdomens. The real oddity of the genus Microdon is in its larvae and pupae.
Patients generally have tender abdomens as a symptom. Symptoms do not include fever, vomiting, or leukocytosis. The pain is typically located in the right or left lower abdominal quadrant. When there is pain in the right lower quadrant, it can mimic appendicitis; however, it more commonly mimics diverticulitis, with pain present on the left side.
Identifying these dragonflies to species can be difficult. The cerci of males, on the tip of the abdomen, are distinctively shaped in each species, as are the subgenital plates on female abdomens. In some species, the subgenital plate is large and projecting, and is used as a "pseudo-ovipositor" for inserting eggs into a substrate.
Magellanic penguin on Argentina's coast Skeleton of a magellanic penguin Magellanic penguins are medium-sized penguins which grow to be tall and weigh between .Magellanic penguin Spheniscus magellanicus. BBC.co.uk The males are larger than the females, and the weight of both drops while the parents raise their young. Adults have black backs and white abdomens.
The abdomen is grey and slender, with a median black stripe. It is checkered with a shifting pattern and black reflecting spots.Sarcophaga most resemble the blow fly, but never have metallic colored abdomens. There are no bristles on the middle tibia of the fly, but the hind tibia has fringed or long hairs irregularly placed.
Calliphoridae adults are commonly shiny with metallic colouring, often with blue, green, or black thoraces and abdomens. Antennae are three-segmented and aristate. The arista are plumose the entire length, and the second antennal segment is distinctly grooved. Members of Calliphoridae have branched Rs 2 veins, frontal sutures are present, and calypters are well developed.
Stage I adult male Pinnotheres novaezelandiae Adult female New Zealand pea crabs have a soft-shelled exoskeleton. Their carapace is oval in shape, ranging in size from wide. Sexually mature adult females almost always have eggs that are tucked under their abdomens, giving them a more spherical appearance. Adult females are opaque white in colour.
Leptopanorpa is a genus of scorpionflies that mainly distributed in Java, with two species also occurring in Sumatra. The males have elongated abdomens which can they can use to compete with other males and these abdomen are also sexually displayed to females. A recent revision found that the genus was nested within a paraphyletic Neopanorpa.
Marcy and Lucy experience accelerated pregnancies, culminating when Patrick's half-alien children violently explode from their abdomens. Patrick hides his rapidly growing sons on the property of his father, Senator Judson Ross. Meanwhile when Patrick has sex, Eve experiences excitement. The next day, Patrick tells his father he cannot remember the previous night's events.
Bolas spiders are small nocturnal animals with oddly 'lumpy' abdomens. Females may grow up to 15 mm or 1/2", while the males, which are smaller, measure in at about 2 mm or 1/16". Several Mastophora species (e.g. M. cornigera) look like bird droppings, which enables them to rest unnoticed at day in fairly exposed places.
Adults of the family usually emerge in late spring or early summer, April through June. Larvae are flattened and brown in color, and they are roach-like in appearance because of the expanded thoracic plates covering the bases of their legs, heads, and abdomens. Tapering gills occur on the thorax at the bases of the legs.
The caudal peduncle is thin and bears slight lateral keels. Males have shorter abdomens and longer caudal peduncles than females. The caudal fin is broad and triangular, with nearly symmetrical upper and lower lobes and a prominent notch in the trailing margin of the upper lobe. The dermal denticles are flattened and not toothed or elevated on stalks.
These obligate parasites infect the developing wasp larvae in the nest and are present within the abdomens of female wasps when they hatch out. Here they remain until they thrust through the cuticle and pupate (males) or release infective first-instar larvae onto flowers (females). These larvae are transported back to their nests by foraging wasps.
The larvae of C. sitchensis have six tergites at the megalopal stage. Upon reaching the adult stage, the first and second abdominal segments have fused and the sixth tergite and telson are whole. C. sitchensis males and females have symmetrical abdomens, yet females have a greater number of accessory plates on the left side of the third tergite.
As with the reproductive females, the reproductive males also appear to be bigger in size than their non- reproducing counterparts but not as much so as in the case of the females. These males also have visible outlines of the testes through the skin of their abdomens. Unlike the females, there are usually multiple reproducing males.
Abdomen is mainly black, with thin pale rings. The top of the abdomen (eighth and ninth abdominal segments) is blue, with black markings on sides.Odonata Central The males' abdomens shows tiny projections off the tip (hence the common name verticalis of this species).Wisconsin Odonata Survey Females are usually grayish-blue, with greyish markings on the abdomen.
Elements of Ctenopterus (1-7) Stylonurids, which lived from the Ordovician to Lower Permian periods, were small to very large forms with scales developing into tubercules and knobs. The prosoma (head) exhibited variable shape, with arcuate compound eyes located subcentrally, or anteriorly. Their abdomens were slender. Their walking legs were long and powerful, sometimes characterized by spines.
Orange bluets are similar to cherry, burgundy, and scarlet bluets. All three bluets are red not orange. General vesper bluets are similar, but the black humeral stripe is either lacking or narrowly reduced in that species. Threadtail damselflies are orange and are found alongside the orange bluet, but they will have much longer and thinner abdomens.
The naiad is an active predator and are able to swim by jet propulsion. They squirt water out from the ends of their abdomens. They will generally take several years to mature, and when the immature changes into a dragonfly, it does so at night. This behavior probably was evolved to avoid being eaten be daytime predators.
Honey ants, also called honeypot ants, are ants which have specialized workers (repletes, plerergates, or rotunds) that are gorged with food to the point that their abdomens swell enormously. Other ants then extract nourishment from them, through the process of trophallaxis. They function as living larders. Honeypot ants belong to any of several genera, including Myrmecocystus and Camponotus.
This species of bee can be distinguished by the lack of pollen baskets. The bee features have a dark face with yellow hair in its vertex and with dark brown wings. Its thorax has variations between black spots or patches. For females, they only have black abdomens but males can vary in their hair color patterns.
Polistes biglumis bimaculatus Polistes biglumis can reach a length of up to (queen), (workers), (males). It is a larger species of wasp in comparison to its relatives in Polistes. It also exhibits darker coloration than that of other paper wasps; it has a black petiole for both sexes. The females exhibit black abdomens as well, with rare yellow spots.
When other insects approach the nest, the dominant individuals (functional queens) may vibrate their wings or assume a stance of alarm to warn the other females of approaching danger. Females also demonstrate alarm through agitated movement. This is usually demonstrated by contracting and expanding their abdomens or by holding their antennae straight out from their bodies.
Then they join their bodies together end to end at their abdomens. Here, the male passes the sperm to the female's egg-laying tube, which will soon be fertilised by the sperm. Many animals make plugs of mucus to seal the female's orifice after mating. Normally such plugs are secreted by the male, to block subsequent partners.
Worker bees of a certain age secrete beeswax from a series of exocrine glands on their abdomens. They use the wax to form the walls and caps of the comb. As with honey, beeswax is gathered by humans for various purposes such as candle making, waterproofing, soap and cosmetics manufacturing, pharmaceuticals, art, furniture polish and more.
Non-professionals commonly confuse carpenter bees with bumblebees; Sourced from Mitchell, T.B. (1962). Bees of the Eastern United States, Volume II. North Carolina Agricultural Experiment Station. Tech. Bul. No.152, 557 p. the simplest rule of thumb for telling them apart is that most carpenter bees have a shiny abdomen, whereas bumblebee abdomens are completely covered with dense hair.
Their total length is 21–43 cm, with the body being 15–25 cm and the tail being 6–8 cm. They have soft, thick, silver fur on the top of their bodies, and white or yellow fur on their abdomens. They have four toes on their front feet, and five toes on their back feet.
Tramea is a genus of dragonflies in the family Libellulidae, the skimmers and perchers. Species of Tramea are found in tropical and subtropical regions around the globe. They typically have colored bases to their otherwise translucent hindwings. In particular when they fly, this creates the impression of their carrying bags at the start of their abdomens.
They live in and around reefs at depths ranging from deep at the continental shelf. They can be dark red and orange above with paler yellowish abdomens or grey-green brown with the paler underside. The more tropical animals tend to have the brighter colours. Adult carapaces can grow up to in length and can often exceed in underfished areas.
The boat-billed heron grows to about long. Adults are pale grey to white in color, with chestnut-colored abdomens and black flanks. The massive, broad, scoop-like bill, which gives rise to this species' name, is mainly black. This bird is also adorned with a crest which is thought to be used in mate attraction as it is larger in males.
Adults have stout, tapered abdomens, slightly elongated legs, with aristate antennae. Males are sexually dimorphic with holoptic eyes. Adult athericids usually rest on the upper surface of leaves, near the streams from which they emerge, or more inland if they are looking for a blood meal. Athericids commonly stroke or palpate the surface of leaves, an action they share with the Tabanidae.
White-tailed spider with egg sac White-tailed spiders are spiders native to southern and eastern Australia, and so named because of the whitish tips at the end of their abdomens. The body size is up to 18 mm, with a leg-span of 28 mm. Common species are Lampona cylindrata and Lampona murina. Both these species have been introduced to New Zealand.
Oonopidae, also known as goblin spiders, is a family of spiders consisting of over 1,600 described species in about 113 genera worldwide, with total species diversity estimated at 2000 to 2500 species. The type genus of the family is Oonops Keyserling, 1835. Goblin spiders are generally tiny, measuring about 1 to 3 millimeters. Some have scuta, hardened plates on their abdomens.
Rock fragments found in the stomach are likely to have been ingested accidentally. Females carry their egg mass around on their abdomens, under their tails, for several months until the eggs hatch. During this period the females are likely to hide away more in crevices and spend less time feeding. Males do not change their feeding behaviour during the breeding season.
M. mexicanus repletes also vary in the content of their "honey" or food they carry. They can be classified according to the colors of their distended abdomens: dark amber, amber, milky and clear. Each color is thought to correspond with a particular food source. Dark amber and amber repletes contain sugars such as glucose and fructose, mostly likely from the nectar of flowers.
Because the T-position is exhibited in other species than just C. aeneus, it is likely that they also exhibit this behavior. In the wild, eggs are laid on waterweeds. Males do not form territories or compete over females; interference between males might only happen when two males present their abdomens simultaneously. On the other hand, females do not choose between males.
Females of the species have very wide abdomens, much wider than long, giving them a horizontal appearance that is further accentuated by their spines. They have three pairs of spines on the abdomen. The first (anterior) pair is usually small and conical. The second (median) pair is long and strong, generally horizontal but often curving slightly backward and downward or even slightly forward.
The hairs are bicolored, with the base of the hair lighter than the tip. Some individuals have been observed with a white band across their abdomens that is variable in size. The ears of bonneted bats are large and forward-facing, their position giving the head a bonnetlike appearance. Their skulls have short, deep basisphenoid pits which aid in vocalization.
Marginocephalians have simple, peg-like teeth surrounded by rhamphotheca, a horny sheath of keratin. The teeth are arranged in batteries for easy replacement and have serrations which may have been useful for cutting up vegetation. Marginocephalia evolved several methods for breaking down vegetation. Pachycephalosaurs had especially large abdomens with broad girths and elongate sacral ribs suggesting the presence of a large stomach.
Tent caterpillars secrete silk from a spinneret wherever they go, and frequently-used pathways soon bear conspicuous silk trails. As the caterpillars move about the tree, they largely confine their movements to these trails. They lay down pheromones along the trails by dragging their abdomens. Caterpillars that find food may overmark the exploratory trails they follow back to the tent, creating recruitment trails.
Minor males have been defined as those with head sizes less than 6.3 mm, while major males have head sizes above 6.3 mm. Males are also allometrically sized, meaning that those with larger heads also have larger mandibles and broader abdomens. The largest of the males are comparable in size to the females. Sexual dimophism can also be seen in the bee coloring.
Adult females additionally have two teat-like projections on their abdomens, called pubic nipples or false nipples, which are not connected to mammary glands. Only a few other bat families have pubic nipples, including Hipposideridae, Craseonycteridae, Megadermatidae, and Rhinopomatidae; they serve as attachment points for their offspring. In a few horseshoe bat species, males have a false nipple in each armpit.
R. revolutionalis are small, dark, reddish brown wasps with body lengths of 8 to 10 mm. When viewed closely, they have remarkable patterns on their bodies, and they have eyes with multiple lenses. They are slightly smaller than species from the family of Polistes. This is because their abdomens have a segment after the waist that is slimmer than the following segment.
During the day, foragers search for flowers and small prey. They bring back soft insects for the larvae and nectar for the adults. When temperatures are high, workers will often raise their abdomens, draw their legs in, and fan their wings rapidly in an effort to cool down the nest. They also continually construct and take care of the cells in the comb.
The dragonhunter (Hagenius brevistylus) is a clubtail dragonfly of the eastern United States and southeastern Canada. closeup of head It is much larger than any other North American clubtail, at , with black and yellow markings and green eyes. Males can be distinguished at a distance by their habit of curling their abdomens under while flying, forming a sideways J shape.Kurt Mead.
Snow crabs have a very high reproductive potential; each year, every female carries eggs. Females are fertilised internally and can carry up to 150,000 eggs under their abdomens after mating. Females usually lay their eggs in very deep areas of the ocean, such as in deposits of phytodetritus. Males also are capable of mating at both immature and mature stages of their lives.
Egg sacs have been observed through September, with later egg sacs containing fewer eggs/spiderlings. It is not known whether the later egg sacs are repeat layings by the same female. Females have been observed moving their egg sac around their web, carrying it under their abdomens, especially when disturbed. Spiderlings molt once in the egg sac prior to emerging as second instars.
These women have a red hourglass-shaped birthmark on their abdomens, similar to those found on black widow spiders. They are practically indestructible in spider form; the only thing that can kill them is fire. The twin who was bitten by the spiders is the one affected by the curse. Mark calls Laura and finds out Leigh is on her way.
It is not considered threatened by the IUCN. The females grow to be larger than the males, to a length of . They can be either light green or dark green colors and they have black spots around their backs and heads. Males can have more colors on the sides of their abdomens, such as orange, green, purple, black, and yellow.
L. dorsata females are a variety of colors, varying between chestnut to dark brown. Shade generally varies with age, with individuals becoming darker in color as they get older. However, egg-laying females sometimes exhibit yellow patterns on the head and thorax. The abdomens of this species are generally an elongated diamond-like shape and the wings have a flattened semi-circular shape.
Xysticus and Coriarachne are dark brown or reddish-brown crab spiders often encountered on weeds or trees. While similar to the 'flower spiders', they tend to have shorter, sturdier legs. Many, but not all, species have abdomens more patterned than most Thomisus species, rather like some of the Synema species. Some however, that are more terrestrial, resemble earth in colour and texture.
Platycnemis acutipennis is the only European damselfly which combines an orange-red abdomen and blue eyes. The male has moderately wide hind tibias (wider in both P. pennipes and P. latipes; and the males of both those species have blue abdomens). The thorax is buff-coloured with black stripes. There is an orange spot near the tip of each wing.
Macracantha is a genus of Asian orb-weaver spiders recognized as containing a single species, Macracantha arcuata. Macracantha is notable for the extremely long, curved spines on the abdomens of female members of the genus; Eugène Simon created the taxon name from the Greek words (large, long) and (spine). It occurs from India and China through Southeast Asia to Borneo.
This produces a suture of fine silken threads that secures the leaves together. More leaves are attached in a similar manner to enlarge the nest. Weaver ants feed on insects and other invertebrates, their prey being mainly beetles, flies and hymenopterans. They do not sting, but have a painful bite into which they can secrete irritant chemicals from their abdomens.
Vibrant blue color of Morpho butterfly due to structural coloration has been mimicked by a variety of technologies. Structural coloration produces the rainbow colours of soap bubbles, butterfly wings and many beetle scales. Phase-separation has been used to fabricate ultra-white scattering membranes from polymethylmethacrylate, mimicking the beetle Cyphochilus. LED lights can be designed to mimic the patterns of scales on fireflies' abdomens, improving their efficiency.
Retrieved 20 August 2012. Any small crustacean which resembles a shrimp tends to be called one.Rudloe & Rudloe (2009) They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.
Before reproducing, mature females display dimorphic features in an attempt to attract males. Females lower the tips of their abdomens and raise their wings slightly to expose more of the uppermost side of the abdomen, thus releasing pheromone to attract a mate. However, sexual cannibalism is prominent among pairs of I. diabolica that remain in captivity. Due to their precautious nature, intrusive environments lead to aggressive behaviour.
A wet specimen is a specimen preserved in fluid, often 70% alcohol. Specimens that would receive this preservation technique are usually soft-bodied, such as caterpillars, larva, and spiders because of their soft abdomens. This is done to minimize shriveling allowing the identifying characteristics to be preserved as true to life as possible. Hard-bodied insects may also be preserved temporarily in alcohol before pinning.
Their queens are wingless and have abdomens that expand significantly during egg production. This allows for the production of 3-4 million eggs every month and often results in synchronized brood cycles, thus each colony will be formed of millions of individuals that descend from a single queen. These three traits are found in all army ant species and are the defining traits of army ants.
The pupae are orthorrhaphous which means that adults emerge from the pupa through a straight, longitudinal seam in the dorsal surface of the pupal cuticle. The bodies and legs of most adult Nematocera are elongated, and many species have relatively long abdomens. Males of many species form mating swarms like faint pillars of smoke, competing for females that visit the cloud of males to find a mate.
When tufted males clap, females look towards them and display a greater number of tap displays to them than to the gray morph. Females also respond to tufted morphs' clapping more often by settling than for gray males. However, after the females look towards the males, gray males approach the female more often than the tufted male. Females often tip their abdomens from side to side.
Doctors described removing "ball-bearing type" metallic beads a little larger than BBs and small carpenter-type nails about long. Similar objects were found at the scene. The New York Times cited doctors as saying that the bombs mainly injured legs, ankles, and feet because they were low to the ground, instead of fatally injuring abdomens, chests, shoulders, and heads. Some victims had perforated eardrums.
While flying, some Saddlebags Gliders (genus Tramea) lower their abdomens into the shade provided by dark patches at the bases of their hindwings. The same behavior has been observed in Pseudothemis zonata, which has a similar hindwing patch. Dragonflies also use postural thermoregulation to increase body temperature. Keeping the flight muscles in the thorax warm is especially important, since otherwise the insect cannot fly.
Their American name "darner" stems from the female abdomens looking like a sewing needle, as they cut into plant stem when they lay their eggs through the ovipositor. The dragonflies mate in flight. The eggs are deposited in water or close by. The larvae (nymphs or naiads) are generally slender compared to those of other families, with a long and flat extensible lower lip (labium).
Social and cultural perceptions of the outward appearance of the abdomen has varying significance around the world. Depending on the type of society, excess weight can be perceived as an indicator of wealth and prestige due to excess food, or as a sign of poor health due to lack of exercise. In many cultures, bare abdomens are distinctly sexualized and perceived similarly to breast cleavage.
The etchings of the bodies in La Marche have distinct characteristics as well. Generally, the etchings are those of women. The bodies of the women were constructed in a diamond shape, with a small head, large abdomens suggesting obesity, and small feet. Men also were etched with large bodies, although this was not so prominent in the men as it was in the women.
One of the females was observed to oviposit at about 7:30 pm PDT. She laid a total of 40 eggs in the sand. The eggs were about 1.5 x 3 millimeters (less than 0.1 square inch), almost kidney-shaped, and pure white with a slight pink iridescence. Female flower-loving flies possess specialized egg-laying organs on the last segment on their abdomens (acanthophontes).
Adult garden tiger moths exhibit clear warning signals, which they share with other tiger moths to advertise very real toxicity upon consumption. Adults can also spray an irritating compound when threatened. The chemical, produced in glands that are exposed when threatened, is a choline ester. A similar compound is found in the tissues of the adults, with the eggs, gonads, and abdomens having the highest concentrations.
In addition, they were also observed to exhibit another remarkable maternal behavior. A dense cluster of small nymphs were photographed being carried around by adult females. The nymphs were firmly clutching unto the bottom side of the abdomens of the adults and to each other, forming a compact mass. The females seem unimpeded by their burden and were able to walk around normally and even fly.
Heteronympha cordace has a wingspan ranging from , with females generally larger than males and with stouter abdomens. The uppersides of the wings are black to dark brown with orange to brownish-orange markings. The markings contain a blue-centered black subapical eyespot and a larger blue-centered black subtornal eyespot. The underside of the wings are lighter in hue and have more extensive orange areas.
When outside the nest they try to run away from attackers, and only use autothysis when in the nest to block tunnels up, preventing attackers entering. Old workers of Neocapritermes taracua develop blue spots on their abdomens that are filled with copper-containing proteins. These react with a secretion from the labial gland upon autothysis to form a mixture which is toxic to other termites.
This ant lives in association with the mealybug, Xenococcus annandalei in its underground nest. The mealybug is a subterranean species and sucks sap from the rootlets of certain trees, particularly species of Ficus and the coconut palm. It exudes drops of honeydew which form part of the diet of the ant. Worker ants tend the mealybugs and stimulate the production of honeydew by stroking their abdomens.
Hebrids are small, ranging from lengths of 1.3 to 3.7 mm. They have a characteristic layer of short, dense hairs that cover their entire bodies, except on their abdomens and appendages, from which they derive the common name "velvet water bug". They have tarsi in two segments, with their hing legs shorter than their bodies. Unlike the Veliidae and Mesoveliidae, they are known only as winged forms.
Scaptotrigona postica are medium-sized, averaging 1.2 cm in length and cross-sectional area of 5.3 mm2. They appear dark gray with some sections of dark yellow in color, with black eyes. Queens are the largest bees in the nest, averaging 38–50 mg, and are identifiable by their swollen abdomens. Also, they have more of the yellow coloring than the workers and drones.
Another virus, the Kakugo virus, has an RNA sequence that is 98% similar to DWV. It is considered a subtype of the DWV species. It is found only in the mushroom bodies of aggressive, guard honeybees. Bees that are significantly affected by DWV also have measurable titers of the virus in their heads while bees that are symptomless only produce titers in their abdomens or thoraxes.
Exactly which artists, beside Pehrson, who took part in the competition is still wrapped in mystery. An inscription of the name of the award's winner, and the category in question, is glued to the underside of the beetle. The following text is engraved under the abdomens of each beetle: "Guldbaggen: comic, tragic, bizarre, outstanding - as the film's contrast-rich world. Its shimmering flight - operating filmstrip".
Males aggressively court female members of the school, leading to a quick upward spawning rush toward the surface of the water during which eggs and sperm are released. The eggs are small, approximately in diameter. The eggs are pelagic, each containing a single droplet of oil for flotation. The fertilized eggs hatch in twenty-four hours, revealing small, translucent larvae with silvery abdomens and rudimentary caudal spines.
Various species of Culicoides can be found worldwide, and in some areas, their high numbers make them a biting nuisance to humans and domestic animals. Culicoides species are stout flies with short vertical probosces and wings folded scissor-like over their abdomens at rest. They generally measure 1–4 mm in length. The wings of most species have a pattern of light and dark marks.
Adult cluster flies in North America are slow-flying insects that are active during warmer months. Once the weather becomes much cooler, P. rudis will seek shelter, usually in homes and buildings. The flies have also been documented staying in tunnels made by beetles in timber and in animal burrows. Before overwintering, cluster fly’s abdomens are full of fat globules that may be left over from its larval fat bodies.
Moths tend to have stout and hairy or furry-looking bodies, while butterflies have slender and smoother abdomens. Moths have larger scales on their wings which makes them look more dense and fluffy. Butterflies on the other hand possess fine scales. This difference is possibly due to the need for moths to conserve heat during the cooler nights, or to confound echolocation by bats, whereas butterflies are able to absorb sunlight.
The abdomens of diplurans bear eversible vesicles, which seem to absorb moisture from the environment and help with the animal's water balance. The body segments themselves may display several types of setae, or scales and setae. Diplurans possess a characteristic pair of cerci projecting backwards from the last of the 11 abdominal somites. These cerci may be long and filamentous or short and pincer-like, leading to occasional confusion with earwigs.
Platycypha males will hover in front of a female, thrusting their bright white legs forward in front of their heads. Rhinocypha will bob up and down, often low over fast-flowing streams, displaying their bright-coloured bodies and wings. Male members of the family Protoneuridae with vividly coloured wings display these to visiting females. Swift forktail (Ischnura erratica) males display to each other with their blue-tipped abdomens raised.
These median spines are about 4.5 millimeters long and curve back and slightly downward. The rear pair of spines are about 2 millimeters long. Female abdomens are marked with depressed black sigilla. Above, the front edge of the abdomen bears 10 sigilla in a curved row, the middle four relatively small and the outermost large and egg-shaped; the larger outer sigilla are also visible on the underside of the abdomen.
The name honeypot ant comes from the peculiar development of replete workers, whose abdomens become so swollen with food that they are used by the rest of the colony as living food storage. They are "drained" during famine, usually the wintertime, to sustain the colony. This behavior is an example of the caste system within ants and other eusocial insects. Repletes are a subset of the sterile "helper" caste.
Like workers, soldiers, and nymphs, they are eyeless. Ergatoids are seldom found in nature. Brachypterous neotenics, which are common in the French population of R. flavipes (formerly R. santonensis), and possibly other populations as well, develop from nymphs via a nymph-like pre- brachypterous neotenic stage. They can be distinguished from nymphs by their shorter wing buds (brachy-, "short" + -pterous, "having wings"), darker pigmentation, slight sclerotization, and longer abdomens.
The workers from the same colony maintain identical paternal alleles and one of two maternal alleles, resulting from the single mating habits of the queen. The workers can be identified by the aggressive mannerism with which they protect and defend the nest. Additionally, workers of this species maintain black/dark brown heads, scutellums, metasomas, and abdomens, with no stripes. Their thorax is measured to be around 2.44 mm wide.
The thickened skin helps to reduce water loss in its dry habitat. It also serves as a kind of plug to shield itself from predators. This phenomenon is called phragmosis and occurs in perfection in the spider genus Cyclocosmia (Ctenizidae). However, some parasitic wasps have evolved paper- thin abdomens and long, slender ovipositors and lay their eggs on the softer skin at the front of the spider's opisthosoma.
Palystes species are large spiders, with a body length of 15–36 mm, and a leg span up to 110 mm. Their top side is covered in tan to dark tan velvety setae (hairs). The underside of their legs is banded in colour, and their legs and abdomens may be interspersed with slightly longer setae. They have a large moustachial stripe below their front eyes, and extending down their fangs.
Some tarantula species exhibit pronounced sexual dimorphism. Males tend to be smaller (especially their abdomens, which can appear quite narrow) and may be dull in color when compared to their female counterparts, as in the species Haplopelma lividum. Mature male tarantulas also may have tibial hooks on their front legs, which are used to restrain the female's fangs during copulation. Males typically have longer legs than the females.
Dragonflies may position their wings to reflect sun onto themselves, or, if they are perched on a warm surface, to form a "greenhouse" over the thorax. When the sun is low in the sky, they may raise or lower their abdomens so that their bodies are perpendicular to the sun's rays, maximizing the surface area that receives direct sun; although this can resemble the obelisk posture, the purpose is opposite.
Most often times than not, when two males interact with one another, it usually involves a fight of some sort. These interactions usually behin when the spiders about 10-15 cm away from the other. They each separately raise their bodies, have their legs hunched, and they bend their abdomens facing one another. The C. umbertica start slowly coming towards one another and their palps begin to vibrate.
Pholcids are thin and delicate arachnids. The body (resembling the shape of a peanut) is approximately 2–10 mm (0.08–0.39 inch) in length, and the legs may be up to 50 mm (1.97 inches) long. Pholcus and Smeringopus have cylindrical abdomens and eyes arranged in two lateral groups of three and two smaller median contiguous eyes. Arrangements of eight and six eyes both occur in this family.
He fitted them with wires glued to their abdomens by sealing wax, replacing their legs. Starewicz animated these puppets with stop-motion to recreate their fighting behavior as accurately as possible. The result was not only the first recorded use of puppetry in film, but the first use of dead insects as stop-motion puppets. Starewicz would make widespread use of stop-motion throughout his career as a filmmaker and animator.
Caterpillars of this family are large and are most often hairy, especially on their sides. Most have skin flaps on their prolegs and a pair of dorsal glands on their abdomens. They feed on leaves of many different trees and shrubs, and often use these same plants to camouflage their cocoons. Some species are called tent caterpillars due to their habit of living together in nests spun of silk.
During nest construction, females transfer olfactory cues onto their nests to facilitate nest recognition. Specifically, they will transfer these hormones by running their abdomens along the nest or excreting liquid from the tip of the abdomen. The olfactory cues are especially concentrated around the nest entrance. When these olfactory cues were experimentally removed, female M. rotundata were unable to identify their own nests, revealing the importance of these chemicals.
Male adult B. nobilis flies have been described in less detail than females. Their abdomens are brown, but existing descriptions focus lies on their reproductive organ attached to the abdomen: the adeagus. Adeagi of B. nobilis males are arched, small and stout, tapering into a blunt dististyle, a blade-shaped accessory on the adeagus. Males, like females, have antennae on their heads, but they also sport yellow, fan-like plumage.
T. grallator spiders may change color depending on their diet. This color change may occur because of the translucent quality of their abdomens. Experimental studies have shown that color pigments can be retained in the abdomen for two to six days, and the color generally shifts from translucent yellow to orange. Once the food is digested and excreted, the color of the abdomen returns to its original translucent pale yellow.
Eutreta diana is a species in the family Tephritidae, known as fruit flies in North America and picture wing flies in Europe. Females lay eggs in vegetative buds of several species and subspecies of sagebrush in western North America. Larvae induce woody galls near their oviposition site and feed on the plant internally until they mature. Adults have "pale green eyes, white-dotted black wings, and bright red abdomens" (Goeden 1990).
In male lice, the front two legs are slightly larger than the other four. This specialized pair of legs is used for holding the female during copulation. Males are slightly smaller than females and are characterized by a pointed end of the abdomen and a well-developed genital apparatus visible inside the abdomen. Females are characterized by two gonopods in the shape of a W at the end of their abdomens.
They have black cephalothoraxes and abdomens with golden urticating hairs. The coxae, trochanters and femurs are also black, but the patellae, tibiae, metatarsi, and tarsi are reddish light brown. K. brunnipes males differ from others in the Theraphosinae subfamily by having a long and downwards pointing embolus with prolateral accessory keels, and by the ability of the first metatarsus to fold between the two branches of the tibial spur.
The Mariana fruit bat is a mid-sized bat which weighs , and has a forearm length of 5.3 to 6.1 in (13.4 to 15.6 cm). Males of the species are slightly larger in size than the females. Their abdomens are colored from black to brown, while also having gray hairs. The mantle and the neck are a brighter brown to golden brown color and the head varies from brown to black.
Adults keep close to a site with host plants, thus the species forms small colonies. The females, however, may disperse in search of more hosts. The butterfly's flight is slow, unlike the swift, erratic flight of many other Lycaenidae. Like many Lepidoptera, male Atalas have hair-pencils (coremata) on their abdomens used in courtship—the male hovers in front of the female, wafting pheromones exuded from the pencils in her direction.
Bees also developed structures known as scopal hairs and pollen baskets to collect and carry pollen. The location and type differ among and between groups of bees. Most species have scopal hairs on their hind legs or on the underside of their abdomens. Some species in the family Apidae have pollen baskets on their hind legs, while very few lack these and instead collect pollen in their crops.
Female long-horned orb-weavers have tough, shell-like abdomens armed with three pairs of spines. The spectacular middle (median) spines project upward and outward, curving in toward each other along their length. They are up to three times as long (20-26 mm) as the abdomen is wide (8-9 mm). The front (anterior) and rear (posterior) spines are short, relatively inconspicuous, and roughly equal in length.
A Red king crab in the collection of the Children's Museum of Indianapolis. The example of king crabs (family Lithodidae) evolving from hermit crabs has been particularly well studied, and evidence in their biology supports this theory. For example, most hermit crabs are asymmetrical, so that they fit well into spiral snail shells; the abdomens of king crabs, even though they do not use snail shells for shelter, are also asymmetrical.
Two mosquito fossils have been found that show very little morphological change in modern mosquitoes against their counterpart from 46 million years ago. These fossils are also the oldest ever found to have blood preserved within their abdomens. The mosquito Anopheles gambiae is currently undergoing speciation into the M(opti) and S(avanah) molecular forms. Consequently, some pesticides that work on the M form no longer work on the S form.
3542: 1-18 Two layers are formed, an inner layer of fine particles and an outer layer of coarser particles. The formation of these two layers may be the reason for the presence of long and short trichomes on the nymphs. Nymphs may use the serrated setae present on their abdomens to assist in loosening substrate for use in camouflage. The camouflage may assist the nymph in avoiding detection by both predators and prey.
Female four-spined jewel spiders are distinctively shaped and coloured. Their abdomens are flat, oblong, and curved slightly forward, 5-6 mm wide, excluding spines. The corners of the abdomen are armed with short spines, the rear pair slightly longer than the pair in front. Unlike most members of its genus, G. quadrispinosa lacks a third pair of spines on the hind margin of its abdomen, so it is four spined or quadrispinose.
As the ant develops, the nematode also develops and moves to the gaster in the ant's abdomen. This is where the adult nematodes mate and the eggs begin to develop within the female nematode. These developing embryos are the cause of the red colour in infected ants' abdomens. Older ants are sent out to forage while the eggs in infected ants develop and cause the abdomen to become red and look similar to a berry.
Water-repellent legs keep them alive on both fresh and salt water, enabling them to survive waves up to 0.5 metres in height. In wind many species raised their legs or abdomens to use as sails, propelling themselves across the water's surface. Many species of spiders also drop silk to anchor themselves in place while afloat. Said spiders did not show these behaviours on land, suggesting that they are adaptations to water.
Strangely, a few Yuks/Kruds - such as Acylius/Maximillian, Krabo/Draffsack and probably Queen Bakrakra/Katheter - are not affected by them. Dragonfly Squadron : The Joyce's main line of defense, these mechanical dragonflies fire blasts of pollen similar to those of the Kolour Guitar from their abdomens. Flower Konnons : The Joyce's new weapons that only appeared in 'No Presents for Khristmas' and shoot like the Kolour Guitar. Kolour Dynamites : Colourful explosions used by Fulgor/Flynn.
The spiders that are courting move down a more winding path and also utilize their abdomens to move as well as use their legs. Although both the courting and walking spiders move in a similar way, the courting spiders tend to spend more time moving than the walking spiders. The courting spiders’ forelegs are also almost always constantly in motion. But, when there is loss of haemolymph fluids, that could also lead to reduced mobility.
One after another, he slices open the abdomens of hundreds of children, and pulls out their entrails. He becomes disgusted with what he is doing, but fears being murdered in the same manner if discovered as a "non-believer" by the other priests, so does not stop. Eventually the other priests, aware of his misgivings, grab the knife from his hand—at which point he awakens from the dream. Dysart interviews Alan's parents.
P. balaenopterae is one of the largest species of copepods within the family Pennellidae, reaching up to in length. The adult females are characterised by a loss of external segmentation and absorption of swimming legs. Pennella species are recognised by the branched outgrowths on the posterior part of their abdomens. The mandibles form a sucking tube for the mouth through which the species feed and adults also have a pair of segmented sensory antennae.
Tabanid species range from medium-sized to very large, robust insects. Most have a body length between , with the largest having a wingspan of . Deer flies in the genus Chrysops are up to long, have yellow to black bodies and striped abdomens, and membranous wings with dark patches. Horse-flies (genus Tabanus) are larger, up to in length and are mostly dark brown or black, with dark eyes, often with a metallic sheen.
Pupae transition to winged state after receiving external signals in the form of temperature change. When the adult Luna moths emerge from their pupae, their abdomens are swollen and their wings are small, soft and wet. The first few hours of adult life will be spent pumping hemolymph (invertebrates' equivalent to blood) from the abdomen into the wings. The moths must wait for the wings to dry and harden before being able to fly.
Colonies vary in size from a few hundred to tens of thousands of individuals. Big colonies usually have multiple queens. The odorous house ant is tough: Injured workers have been observed to continue living and working with little hindrance, some queens with crushed abdomens still lay eggs, and there are documented instances of T. sessile queens surviving without food or water for over two months. They also appear highly tolerant to heat and cold.
Mice, which are known spider predators, were accidentally introduced to Pitt some time before 1951, and may have driven D. schauinslandi extinct there. It is possible that this species could re-establish itself on Pitt Island, if there was suitable predator-free habitat (Pitt Island has mice but not rats); spiderlings lift their abdomens when exposed to a breeze in the lab, which is a behaviour associated with aerial travel by ballooning.
Illustration of adult The female lays batches of between twenty and ninety eggs. These are barrel- shaped and have a number of small projections at the edge of the operculum. The nymphs go through five instars in their growth process and have bluish- black heads and thoraxes and red abdomens. The first instars stay close to the egg mass and the later instars also tend to group together, sometimes feeding on a common prey item.
In 1322, however, Jacobina Félicie was put on trial for unlawful practice. She was placed on trial against the Medical Faculty of Paris solely for the reason that she practiced medicine without a medical license. In her defense, Jacobina believed that it was improper for men to palpate the breasts and abdomens of women. During the trial, there were eight witnesses, all being her patients besides one, that testified to her medical skills.
Though part of the threadtail family, the abdomen of neoneurans, in contrast to that of protoneurans, is no more slender than that of pond damselflies. Males are mostly brightly coloured with red, orange, yellow and blue predominating, but females are less showy. The females do not bend their relatively short abdomens when laying eggs as do protoneurans. Pairs of these damselfly can be seen in tandem over quiet waters at the edges of lakes.
North Carolina State University found that bed bugs in contrast to most other insects tolerate incest and are able to genetically withstand the effects of inbreeding quite well. Male bed bugs sometimes attempt to mate with other males and pierce their abdomens."This Bedbug's Life", The New York Times, 7 August 2010. This behaviour occurs because sexual attraction in bed bugs is based primarily on size, and males mount any freshly fed partner regardless of sex.
C. degeeri C. corticicola Crematogaster is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed.African Insect Life - S. H. Skaife (Longmans, Green — Cape Town) Most species are arboreal. These ants are sometimes known as acrobat ants.
C. ricketti females are long, with a disk diameter of . Their burrows are deep, and only the bottom portion of the burrow is silk lined. These are trapdoor spiders, whose species are distinguished from each other by the pattern of the abdominal disk, the number of hairs on its seam, and the shape of the spermathecae. They have abdomens that are abruptly truncated, ending in a hardened disc that is strengthened by a system of ribs and grooves.
Peacock spider males perform courtship dances that display their boldly patterned mandibles, legs, and abdomens. Females are cryptic brown. Charles Darwin published a book on sexual selection in 1871 called The Descent of Man, and Selection in Relation to Sex, which garnered interest upon its release but by the 1880s the ideas had been deemed too controversial and were largely neglected. Alfred Russel Wallace disagreed with Darwin, particularly after Darwin's death, that sexual selection was a real phenomenon.
Mature female crabs generally molt between May and August, and mating occurs immediately after the female has molted and before the new exoskeleton hardens. Males are attracted to potential mates by pheromones present in the urine of females. Upon locating an available female, the male initiates a protective premating embrace that lasts for several days. In this embrace, the female is tucked underneath the male, oriented such that their abdomens touch and their heads face each other.
Both sexes have tufts of orange to dark orange above the eyes, which are fringed with pale orange hairs. Males' abdomens are yellow-orange to orange- brown with blackish mottling, and on the upper sides are black and light orange hairs, and nine white tufts. Those of females are pale yellow and have black markings with scattered white and orange-brown hairs on the upper side. P. schultzi has relatively longer legs than other Portia, and a "lolloping" gait.
However, at the execution, the indignant samurai cut open their abdomens and allowed their intestines to flow, to shock the French who were observing the execution. After 11 performed their own execution, which matched the number of French killed, the French captain requested a pardon, sparing nine of the samurai to banishment instead. Quoting the Moniteur, the London Morning Post described the executions: This incident was dramatised in a short story, "Sakai Jiken", by Mori Ōgai.
The nominate variety is found throughout the species' range while var. pyramidatus is found only in Europe, where the two varieties are seldom found together. The female has a body length (excluding legs) of up to 14 mm while the male is rather smaller at 9 mm. Adult female marbled orbweavers are 9 to 20 millimeters in length with very large abdomens that are mostly orange with brown to purple markings and spots of pale yellow.
A juvenile female, showing typical white banding The adult female redback has a body around long, with slender legs, the first pair of which are longer than the rest. The round abdomen is a deep black (occasionally brownish), with a red (sometimes orange) longitudinal stripe on the upper surface and an hourglass-shaped scarlet streak on the underside. Females with incomplete markings or all-black abdomens occasionally occur. The cephalothorax is much smaller than the abdomen, and is black.
They will eat just about anything that is the right size. Start feeding the nymphs 1 or 2 days after hatching. 1st instar nymphs get up to 15mm long when their abdomens are expanded so they can tackle and eat large prey. 1st instar nymphs can eat Drosophila melanogaster fruit flies and Drosophila hydei fruit flies and house flies but they could eat things much larger such as small roaches and crickets as well as small moths, et cetera.
The shrimp Palaemon serratus of the infraorder Caridea Shrimp are decapod crustaceans with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata. More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, shrimp may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long narrow muscular tails (abdomens), long whiskers (antennae), and slender legs.Shrimp Encyclopædia Britannica.
The Ampulicidae, or cockroach wasps, are a small (about 170 species), primarily tropical family of sphecoid wasps, all of which use various cockroaches as prey for their larvae. They tend to have elongated jaws, pronounced neck-like constrictions behind the head, strongly petiolate abdomens, and deep grooves on the thorax. Many are quite ant-like in appearance, though some are brilliant metallic blue or green. Most species sting the roach more than once and in a specific way.
For instance, some consider M. amanthonte a subspecies of Morpho melanus, but this is not supported by morphology. Some older studies have identified 75 Morpho species, and newer studies recognize about 30 species. Despite the many species of the Morpho butterfly displayed in collections, they usually have mismatched or missing abdomens which make it difficult for research. Using combined studies of parsimony and Bayesian analyses, Morpho melanus is associated with the M. helenor, M. sulkowskyi and M. amonthonte clades.
Asian giant hornets, Vespa mandarinia, form similar raiding parties to hunt their prey, which usually consists of honeybees. The giant hornets group together and as a team can decimate an entire honeybee colony, especially those of non- native European honeybees. Alone, the hornets are subject to attack by the smaller bees, who swarm the hornet and vibrate their abdomens to generate heat, collectively cooking the hornet until it dies. By hunting in groups, the hornets avoid this problem.
A. hentzi is a rather docile and nonaggressive species.Oklahoma Brown Tarantula RET. Nov.20 2017 When disturbed, like most other tarantulas, A. hentzi maneuvers itself to a stance on its hind legs and raises its front legs in a threatening manner. Additionally, A. hentzi and most other tarantulas found in the Americas have small, coarse, brown or black urticating hairs on their abdomens that they kick in the direction of whatever they may feel threatens them.
The eyelash viper reaches sexual maturity at around two years of age, and the ovoviviparous species reproduces throughout the year in warm environments. Females carry eggs for around six months before they hatch internally, where the young complete their development. Pregnant females have enlarged lower abdomens, and may stop eating in later stages of pregnancy. In a typical brood they give birth to 2–20 live young, which are in length and appear physically similar to adults.
Ants of the genus Camponotus have an intimate relationship with several Korthalsia species, occupying chambers in the fibrous and swollen ocreas at the leaf bases. Here, the ants "farm" scale insects which feed on the palm’s phloem cells, and produce a sweet dew the ants feed on. The ants also beat their abdomens against the dry leaf bases to create a precautionary alarm rattle before attacking en masse. The relationship seems to be mutual, protecting the palms from herbivores.
Adults have yellow coloration under their legs, which may extend to their abdomens, but this characteristic is faint or absent in young frogs. A triangular, buff- colored patch occurs on the snout, and, unlike other frogs in the genus, there is no eye stripe. The throat and chest are often boldly mottled; and the species has indistinct dorsolateral skin folds and granular skin. Males of this species develop nuptial pads on their thumb bases during the breeding season.
Larvae of some Perreyia species travel in groups on the ground and eat dead or dying vegetation. They also travel as groups to find group pupation sites. These groups are a tight-knit mass of larvae crawling over each other looking like a giant slug. In the genus Perga, groups come to periodic halts and individuals within the groups begin to raise and lower their abdomens to communicate to the rest of the group to begin moving again.
Lückemeyer A (2009) The role of chemical communication in the reproductive biology of bumblebees and cuckoo bumblebees. Dissertation, University of Ulm. However, this serves well in the defense of cuckoo bees, as there are no weak points between the abdominal segments of the cuckoo bee for other bees to pierce through using their stingers. Moreover, cuckoo bumblees are slightly less hairy, have shorter tongues, have more pointed abdomens, and contain much sturdier bodies than normal bees.
The largest males are the most aggressive and thus the largest males and females mate, and so on in order of size. When P. clarus males find females, the males court by waving their legs and making their abdomens vibrate against the substrate (leaves, the ground, etc.). Males will court immature and adult virgin females, and also previously mated females. As the male dances, he approaches the female and touches the female cautiously once or twice.
Typical external symptoms include exophthalmia and the presence of hemorrhages in the periorbital and intraocular area, the base of fins, the perianal region, the opercula and the buccal region. In further studies, swollen abdomens and anal prolapsus have been observed. Due to infection, fish have produced lesions in the vascular endothelium that cause blood extravasation, leading to hemorrhages and petechiae at the surface of internal organs. The main organs affected are the spleen, liver, brain, stomach, kidney and heart.
Males, however, have largely yellow abdomens. Adult wasps can be distinguished from the young because they are darkly colored and can fly, whereas young wasps have paler stripes and are flightless. Workers and queens do not exhibit morphological differences, but they can be distinguished physically by the abundance of their fat layers and behaviorally through their relative foraging efforts. Queens have more abundant fat layers and are also significantly less likely to participate in foraging for the nest.
In addition to a differential in the abundance of fat layers in their abdomens, the color of the fat layers is distinct for workers versus queens; the workers exhibited yellow fat layers while the queens exhibited milky fat layers. The nests of P. biglumis are circular or elliptic in shape and are hung vertically via one pedicel. They are largely produced by the foundress during the phases of egg and larvae production. The peripheral cells are generally uninhabited.
Roundworms absorb the nutrients from the animal, which can interfere with digestion and can also damage the lining of the intestine. Animals may not show any outward symptoms of roundworms at all, or in other, usually more severe cases, animals may have diarrhea, vomiting, loss of appetite, experience thinning, dull coats, and in puppies or kittens, can develop distended abdomens, or "pot- belly" appearance. Infection symptoms are similar to infection by other Toxacara species (T. canis, T. cati).
Female adult B. nobilis flies have curved claws. While upper portions of their body, like the head and antennae, are a darker brown or gray color, the majority of females' abdomens are lightly colored with a range from white to yellow and covered in fine black setae. They have one pair of long yellow gland rods running along their body. Adult females have two asymmetrical spermathecae chambers that collect and store sperm, reachable through a short passage.
When the female's shell is still soft the male will invert her to position themselves with their abdomens in contact together. The male then transfers his spermatophores to her gonopores. Once mating has occurred, the eggs will spawn around fifty-seven days later and will have an fecundity between 135,000 and 680,000. Nauplia will hatch from the Speckled swimming crab eggs around eighteen days and will grow into the first stage of crab thirteen days later.
Teletubbies is a British children's television series created by Ragdoll Productions' Anne Wood and Andrew Davenport for BBC. The programme focuses on four multi-coloured creatures known as "Teletubbies", named after the television screens implanted in their abdomens. Recognised throughout popular culture for the uniquely shaped antenna protruding from the head of each character, the Teletubbies communicate through gibberish and were designed to bear resemblance to toddlers. The series rapidly became a commercial success in Britain and abroad.
Army ant Eciton mexicanum workers with N. kronaueri attached between the ants’ petiole and postpetiole. N. kronaueri is noted for its unusual mechanism of phoretic transport - it uses its mouthparts to attach itself to the waist (between the petiole and postpetiole) of medium sized ant workers of the species Eciton mexicanum. Once attached, the beetles appear to mimic the ants' abdomens. To human eyes, this makes it appear that the ant has two abdominal segments, one above the other.
Elephant seals have a very large volume of blood, allowing them to hold a large amount of oxygen for use when diving. They have large sinuses in their abdomens to hold blood and can also store oxygen in their muscles with increased myoglobin concentrations in muscle. In addition, they have a larger proportion of oxygen-carrying red blood cells. These adaptations allow elephant seals to dive to such depths and remain underwater for up to two hours.
Coleusia is a genus of Indo-Pacific pebble crabs of the family Leucosiidae. The six species currently recognised were formerly classed as members of the genus Leucosia but were separated into Coleusia in 2006 based on the fusing of segments 3-5 on the abdomens of the males and the three times axial coiling of the shaft of the first pleopod which bears a tufted lobe on its distal portion and has an elongated apical process.
Palaemnema domina is on the wing from July to September. In the heat of the day adults congregate in dense vegetation and tangled roots of fallen sycamores and cottonwoods within a few feet of the ground and in close proximity to streams. They perch with abdomens dangling and can easily be caught by hand at this time. In the morning and evening and on cool cloudy or rainy days they are active, often moving round in tandem.
Both sexes display by spreading their pectoral and caudal fins, and moving around or by the side of the other sex. Males will sometimes also spread their dorsal fins, repeatedly open and close their mouths, and position themselves on top of the females and rub their abdomens with their bodies. If a female accepts a male for spawning, they form a pair. Occasionally, another male might intrude upon the pair as they are mating and attempt to sneak fertilizations with the female.
As a response to sexual coercion and the costs that females face, one of their counter-adaptations is the evolution of anatomical protection. Females of some species, such as the water striders, developed morphological shields to protect their genitalia from males that want to forcefully copulate. Some Gerridae females have also evolved abdominal spines and altered the shapes of their abdomens to make them less accessible to males. Waterfowl males of the family Aves: Anatidae have evolved a phallus to aid in coercion.
The male display and courtship dance are complex, involving visual and vibratory signals. Several species in this genus were earlier classified in the genus Saitis, containing the Mediterranean Saitis barbipes, which is superficially similar to Maratus (colorful males with an enlarged third pair of legs). Saitis in Australia have enlarged and fringed third legs which they use for display but do not raise their abdomens like Maratus. All species of Maratus are found in Australia, with the exception of Maratus furvus from China.
Suborder Opisthothelae contains the spiders that have no plates on their abdomens. It can be somewhat difficult on casual inspection to determine whether the chelicerae of members are of the sort that would classify them as mygalomorphs or araneomorphs. The spiders that are called "tarantulas" in English are so large and hairy that inspection of their chelicerae is hardly necessary to categorize one of them as a mygalomorph. Other, smaller, members of this suborder, however, look little different from the araneomorphs.
Female black-and-white spiny spiders are 6-9 millimeters wide and possess hard, shiny abdomens armed with six black conical spines. The upper surface of the abdomen is white to yellowish with variable black or dark brown markings and sigilla. The central part of the abdomen's dorsal surface is usually marked with a dark cross-like shape. From individual to individual and across the species' range, the length of the spines and the details of the coloration vary considerably.
The underwings have a strong yellow band and in flight, the moth buzzes, appearing like a bee. The forewings are violet grey when fresh and have a "barklike pattern of swirling black lines" according to David Beadle and Seabrooke Leckie. At rest, they raise their abdomens and are well camouflaged on tree bark, looking like a broken branch (Wagner 2005). Early instars are a pale greenish white, with at first a horn, but later a brown knob near the hind end.
Only wasps leaving the nest notice a disturbance and defend or fight off an intruder. The ones returning to the nest do not detect any disturbance and try to enter the nest. The workers that detect danger show a certain gesture – they rise onto the tips of their tarsi, put forward their heads, turn down their abdomens and constantly vibrate their wings in high frequencies and short beats. This behavior signals other workers to fly to the entrance of the nest and defend.
The abdomen of A. atropos is robust and is covered in brown, feathery down. Yellow striping that highly resembles the colour patterns of a hornet extends part way across each abdominal segment. The intensity and distribution of colour can vary widely in individual specimens, with some individuals occasionally found expressing an indistinguishable "skull-like" pattern on the thorax. Sexual dimorphism Like in most Lepidoptera, female moths of this species tend to be larger than males, appearing bulkier and sporting larger, more robust abdomens.
Androlaelaps casalis formerly known as Haemolaelaps casalis is a species of predatory mite that feeds on other mites and small invertebrates. It cannot bite or sting birds and humans because its mandibles are not designed for sucking but for predation on other mites. Because Androlaelaps casalis mites feed off parasitic mites like Dermanyssus gallinae, individuals with red colored abdomens can be found. This is not due to any blood-sucking by A. casalis but is because it has ingested blood-engorged parasitic mites.
Nicrophorus germanicus Burying beetles have large club-like antennae equipped with chemoreceptors capable of detecting a dead animal from a long distance. After finding a carcass (most usually that of a small bird or a mouse), beetles fight amongst themselves (males fighting males, females fighting females) until the winning pair (usually the largest) remains. If a lone beetle finds a carcass, it can continue alone and await a partner. Single males attract mates by releasing a pheromone from the tip of their abdomens.
Abdominal extracts are differentiated between males and workers, but both come from the Dufour's gland, which is a large, wide, pear-shaped sac. The main chemical component of workers' abdominal extract is geranylgeranyl acetate while the extract from males' abdomens is (Z)-9-nonacosene. Experiments have shown that (S)-(+)-2-heptanol and (S)-(+)-2heptanol/(S)-(+)-2-nonanol (1:1) attract N. testaceicornis workers. However, males do not respond to these chemicals, implying that these compounds do not function as alarm or recruitment pheromones.
The crown is boarded by a black stripe extending from in front of the eyes until the gray auriculars. The tail and wings are blackish with the primaries margined slightly with a grayish external. There is a slight fulvous or tawny tint to the remiges most external parts. One important note is that the Cuzco brushfinch shows considerable variation with the intensity of gray in the underparts - some almost uniformly dark gray below and others that are pale gray with grayish-white abdomens.
Unlike other singing ensiferans, ground weta do not have tibial tympanae. Sexually active males hit their abdomens on substrates, such as leaf or soil surfaces, to produce pre- copulation vibratory sounds as signals for mate attraction; this is known as drumming. The number of abdomen hits on the substrate, the duration of the drumming, and the intervals between drumming all differ between species, these vibrations are believed to be species specific. Pheromones produced from anal secretions may be involved in long-distance communication.
C. textor nests can be found across a number of tree species in Brazil, and they're dominant species wherever they're found. These ants will aggressively defend their nests whenever disturbed, while workers will produce a fairly loud hissing sound through tapping inside their nest with their abdomens. They undergo four larval instars during their development, and will pupate inside a cocoon. The last larval instar, mature larvae produce the silk used in spinning their nests, being held from behind by other workers.
Females have black scales that protrude forwards and backwards on their middle and hind legs. They also have small hairs that cover the sides of the legs and tan abdomens. In comparison to males, females have larger and inflatable pleural sacs, larger wings, thorax length, and hind tibial length, which are the principal sexually dimorphic body parts. The ventral region of the female retina is larger than the dorsal region, which helps them locate encroaching males that are pursuing mating.
There are approximately 2000 species of true water beetles native to lands throughout the world. Many water beetles carry an air bubble, called the elytra cavity, underneath their abdomens, which provides an air supply, and prevents water from getting into the spiracles. Others have the surface of their exoskeleton modified to form a plastron, or "physical gill", which permits direct gas exchange with the water. Some families of water beetles have fringed hind legs adapted for swimming, but most do not.
Aeshna speciosa fossil These are relatively large dragonflies. Their thoraces and abdomens are brown in color, with blue or yellow stripes or spots on the thorax, and yellow, blue or green spots on the abdomen. Natalia von Ellenrieder's 2003 paper demonstrated that the Holarctic and Neotropical species placed in this genus did not share a common ancestor, and proposed the latter be placed in the genus Rhionaeschna. The name Aeshna was coined by the Danish entomologist Fabricius in the 18th century.
It was observed that H. sonorensis females died in a period of 24 to 48 hours after mating with H. cochimiensis males. When examining the females, it was evident that their abdomens were blackened and swollen due to an enormous number of immunoreactions. There is a direct relationship between the increase of mating and the decrease in female's lifespan. Female bed bug mortality rate due to traumatic insemination could be related more to STDs rather than just the open wound.
Their abdomens bear appendages that have been modified into spinnerets that extrude silk from up to six types of glands. Spider webs vary widely in size, shape and the amount of sticky thread used. It now appears that the spiral orb web may be one of the earliest forms, and spiders that produce tangled cobwebs are more abundant and diverse than orb-web spiders. Spider-like arachnids with silk-producing spigots appeared in the Devonian period about , but these animals apparently lacked spinnerets.
Most spiders are insufficiently dangerous or unpleasant-tasting for warning coloration to offer much benefit. However, a few species with powerful venom, large jaws or irritant bristles have patches of warning colors, and some actively display these colors when threatened. Many of the family Theraphosidae, which includes tarantulas and baboon spiders, have urticating hairs on their abdomens and use their legs to flick them at attackers. These bristles are fine setae (bristles) with fragile bases and a row of barbs on the tip.
However, pupae do not feed during this stage; typically they pass their time hanging from the surface of the water by their respiratory trumpets. If alarmed, say by a passing shadow, they nimbly swim downwards by flipping their abdomens in much the same way as the larvae do. If undisturbed, they soon float up again. After a few days or longer, depending on the temperature and other circumstances, the dorsal surface of its cephalothorax splits, and the adult mosquito emerges.
Like most New World tarantulas, they kick urticating hairs from their abdomens and their back legs if disturbed, rather than bite. They are only slightly venomous to humans and are considered extremely docile, though, as with all tarantulas, their large fangs can cause very painful puncture wounds, which can lead to secondary bacterial infection if not properly treated and allergies may intensify with any bite.Schultz, Stanley A. and Schultz, Marguerite J. (2009) The Tarantula Keeper's Guide: Comprehensive Information on Care, Housing, and Feeding (Revised Edition). Barrons.
It has 1 or 2 canine teeth on the upper and lower plates. Initial phase globehead parrotfish are grey-brown, their abdomens bearing three white bands. The range is from the Society and Line Islands in the Pacific west to the Ryukyu Islands in the north, the Great Barrier Reef in the south, and across the Indian Ocean to east Africa. It is found more commonly on outer reefs but can also inhabit lagoons, generally to a depth of around and occasionally down to .
Cooey, then age 19, and Dickens, age 17, took the women to a field behind the Rolling Acres Mall where they raped, stabbed, and tortured them for three and one-half hours, eventually choking and bludgeoning them to death and abandoning the bodies. They also carved X's into the victims' abdomens. Cooey and Dickens each blamed the other for the actual murders, Horonetz having left the car before the violence began. Cooey bragged about the murders to close friends and was eventually turned in to authorities.
Myrmecocystus is a North American genus of ants in the subfamily Formicinae. It is one of five genera that includes honeypot ants.Morgan, R. Biology, husbandry and display of the diurnal honey ant Myrmecocystus mendax Wheeler (Hymenoptera: Formicidae) Worker ants keep and tend plerergates, which are other ants that store large quantities of nutritious fluid in their abdomens to feed the colony during famine times.. Some species engage in highly territorial tournaments, which can result in intraspecific slavery. During the raids, they carry off larvae, workers, and plerergates.
The nymphs of E. vulgata burrow into the sediment at the bottom of ponds. Most burrowing mayfly nymphs use the gills on their abdomens to create a current of water through their burrows, thereby ensuring sufficient oxygen is available to absorb through the tracheae in their skin. The motile, filamentous gills of E. vulgata seem to act as secondary respiratory surfaces and their presence is necessary to the nymph in the low-oxygen environment in which it lives. By contrast, nymphs of Baetis and Cloeon spp.
It is best practice to first work out if your wasp is a worker, queen or drone before separating it into vulgaris vs germanica. German wasps also have black dots on their abdomens, while the common wasp's analogous markings are fused with the black rings above them, forming a different pattern. However, the identification of a wasp as V. vulgaris may be difficult because the normally unbroken black mark on its clypeus can sometimes appear broken, making it look extremely similar to V. germanica.
The unique lethality of their poison is a trait often exploited by certain Native American peoples of Colombia for hunting. The members of this species are characterized by: black dorsums, sometimes covered by orange suffusions; green, yellow, orange, or brownish gold dorsolateral stripes; and black abdomens with blue or green dots. The name Phyllobates aurotaenia is currently applied to two forms: a smaller, large-stripe form and a larger, small-stripe form. These forms are separated by a ravine yet retain the ability to interbreed.
Owning a territory tends to lead to more copulations although the territory itself does not hold any resources or nests. The defense of these territories represents a lek polygyny mating system that is not based on resources. But rather, females perhaps incentivize males to compete for territories by restricting mating to these territories; this way, females know that the territorial males they choose to mate with are strong, healthy males. To attract females to the territories, males can rub their abdomens across the territories to apply pheromones.
In M. beecheii, all females, even those designated to be workers, have the ability to develop as queens. As a result of this potential to self-determine, immature females may try to develop as queens to gain greater reproductive opportunities. When a colony's queen dies, or before the formation of new colonies by swarming, new queens are produced, only one of which is selected to serve in that function per colony. Workers kill the extra queens by biting off their heads, abdomens, and limbs.
Eomaia, like other early mammals and living marsupials, had a narrow pelvic outlet suggesting small undeveloped neonates requiring extensive nurturing. Epipubic bones extend forwards from the pelvis; these are not found in any placental, but are found in all other mammals, including non-placental eutherians, marsupials, monotremes and other Mesozoic mammals as well as in the cynodont therapsids that are closest to mammals. Their function is to stiffen the body during locomotion. This stiffening would be harmful in pregnant placentals, whose abdomens need to expand.
Ambergris is formed from a secretion of the bile duct in the intestines of the sperm whale, and can be found floating on the sea or washed up on coastlines. It is sometimes found in the abdomens of dead sperm whales. Because the beaks of giant squids have been discovered within lumps of ambergris, scientists have theorized that the substance is produced by the whale's gastrointestinal tract to ease the passage of hard, sharp objects that it may have eaten. Ambergris is passed like fecal matter.
Moths are known to engage in acoustic forms of communication, most often as courtship, attracting mates using sound or vibration. Like most other insects, moths pick up these sounds using tympanic membranes in their abdomens. An example is that of the polka-dot wasp moth (Syntomeida epilais), which produces sounds with a frequency above that normally detectable by humans (about 20 kHz). These sounds also function as tactile communication, or communication through touch, as they stridulate, or vibrate a substrate like leaves and stems.
The pair, more colorful female in the front In the wild, male P. pulcher grow to a maximum length of approximately and a maximum weight of . Females are smaller and deeper bodied, growing to a maximum length of and a maximum weight of . Both sexes have a dark longitudinal stripe that runs from the caudal fin to the mouth and pink to red abdomens, the intensity of which changes during courtship and breeding. The dorsal and caudal fins also may bear gold-ringed eye spots or ocelli.
Mature individuals have brown carapaces with short golden hairs (setae) with a slight purple sheen. Females have abdomens with long greyish brown hairs on the front of the upper (dorsal) surface and the sides; males have these longer hairs evenly distributed. Both sexes have legs and palps with short brown hairs with a pink sheen and long brown hairs with darker bases and a whitish apex. The femora, tibiae and metatarsi of the legs have vivid yellow rings on the ends furthest from the body.
Honey bee with deformed wings Deformed wing virus (DWV) is suspected of causing the wing and abdominal deformities often found on adult honeybees in colonies infested with Varroa mites. These symptoms include damaged appendages, particularly stubby, useless wings, shortened, rounded abdomens, miscoloring and paralysis of the legs and wings. Symptomatic bees have severely reduced life-span (less than 48 hours usually) and are typically expelled from the hive. The symptoms are strongly correlated with elevated DWV titres, with reduced titres in asymptomatic bees from the same colonies.
Some species of Gasteracantha have very long, horn-like spines protruding from their abdomens. One feature of the webs of some orb-weavers is the stabilimentum, a crisscross band of silk through the center of the web. It is found in several genera, but Argiope - the yellow and banded garden spiders of North America - is a prime example. As orb-weavers age, they tend to have less production of their silk, many adult orb-weavers can then depend on their coloration to attract more of their prey.
Similar to males, they have iridescent green or gold speckling, though the speckles are concentrated on the opercles or cleithrum (bone that extends from pectoral fin up to the cranium above the gills). Females' eyes are also dark, and their upper and lower jaws range in color from olive-black to pale yellow. Their abdomens are pale yellowish-green, and their bellies are tinted pink. They also have olive-black lateral stripes and dorsal saddles; the color between the dorsal saddles is amber to pale yellow.
One prisoner, Don Carlos Walker Martinez was tied to a tree and tortured by being repeatedly cut with a sword and when the Army could not extract any information they broke both of his legs. Remaining silent, the troops poured a flammable liquid on him and set him on fire; he died an hour later. Other members of the guerrilla band had their abdomens cut open and their organs strung on the trees, their eyes and tongues cut out, and their ears and noses cut off.
The egg laying process begins when a female does low passes above bracken fronds and drop down when they find a suitable spot. Females will then crawl on the bracken littered ground and use their abdomens to probe for likely egg laying spots. Eggs are normally laid once a female crawls over a plant that can serve as a food resource. Eggs may also be laid without any area observation, and without any food plants nearby, as females have been observed to lay eggs within seconds of landing.
It has an inbuilt biological clock and, even when kept in total darkness, turns its light on and off in a circadian rhythm. Fireflies use light to attract mates. Two systems are involved according to species; in one, females emit light from their abdomens to attract males; in the other, flying males emit signals to which the sometimes sedentary females respond. Click beetles emit an orange light from the abdomen when flying and a green light from the thorax when they are disturbed or moving about on the ground.
240x240px Stegodyphus mothers liquefy their inner organs and maternal tissue into food deposits. The African social velvet spider Stegodyphus mimosarum and the African social spider Stegodyphus dumicola are two social spider species that eat their mothers and other adult females, which is unique since social spiders do not tend to exhibit cannibalistic life history traits. In these specific spiders, deceased females are often found shriveled with shrunken abdomens. Offspring suck nutrients primarily from the dorsal part of the adult female's abdomen, and she may still be alive during this process.
They have a delicate appearance and are from twelve to twenty millimetres long with large, membranous, pale green wings which they fold tent-wise above their abdomens. They are weak fliers and have a fluttery form of flight. They are often seen during the evenings and at night when they are attracted by lights. The high green sensitivity of the superposition eyes allows the green lacewings to recognize fresh green leaves that they use to find honey dew produced by aphids, a site for egglaying and a resting place.
In 1946, Kordel was convicted of misbranding dietary supplements and fined $4, 000. For example, he falsely advertised a herbal tablet "Gotu Kola," as offering "erect posture, sharp eyes, velvety skin, limbs of splendid proportions, deep chest, firm bodies, gracefully curved hips, flat abdomens and even pleasing laughter." Kordel came into dispute with the Federal Trade Commission in 1957 and Food and Drug Administration in 1961. Whilst president of Detroit Vital Foods, products from the company, "Michigan Brand Korleen Tablets" and "Frutex Fruit Salad" were discovered to be misbranded with false health claims.
The Australian garden orb weaver spider (Eriophora transmarina) is a very common species of spider with many variants in size, shape, and colour across the coastal regions of Australia. They have very large abdomens when well-fed and exhibit a tremendous colour-range from off-white through tan, brown to almost black. They have a roughly leaf-shaped pattern on the top of their abdomen with a complex outline that is darker than the surrounding area. There may also be several whitish spots or one or more stripes.
Spiders need considerable mobility of their abdomens in their spinning activities, and the Solifugae have no such adaptation. The prosoma comprises the head, the mouthparts, and the somites that bear the legs and the pedipalps. Though it is not split into two clear tagmata, the prosoma does have a large, relatively well-defined anterior carapace, bearing the animal's eyes and two chelicerae that, in most species, are conspicuously large, while a smaller posterior section bears the pedipalps and legs. The chelicerae serve as jaws and in many species also are used for stridulation.
Females have darker abdomens, but with always some blue on the proximal half of each segment; this characteristic resembles brighter azure damselfly females, which can be distinguished by three forward-pointing black spires (ornate bluet females only have the central one). Males in turn closely resemble the southern damselfly males, from which they can be distinguished by serrated hind edges of eye-sports on the top of the head and details in abdomen markings. The period of activity is short: adults fly in the summer, from May to July or mid-August.
Females mature through seven–eight instars in about 75–120 days. Males live for up to six or seven months, while females may live between two and three years. Laboratory tests have shown that redbacks may survive for an average of 100 days, and sometimes over 300 days without any food, those starved at 10 °C faring better than those kept without food at 25 °C. Spiders are known to reduce their metabolic rates in response to starvation, and can distend their abdomens to store large amounts of food.
Redbacks can survive temperatures from below freezing point to 40 °C, though they do need relatively warm summers, with temperatures of 15 to 25 °C for two to three months, to survive and breed. Redback spiderlings cohabit on the maternal web for several days to a week, during which time sibling cannibalism is often observed. They then leave by being carried on the wind. They follow light and climb to the top of nearby logs or rocks before extending their abdomens high in the air and producing a droplet of silk.
At their own nests, guards are not aggressive, but at the entrance of host nests, they form a circle in order to defend it from the hosts and from other insects. Lestrimelitta limao guards surround the outside of hosts nest, aligned side-by-side, before and during a raid. These guard ring robbers occasionally raise their abdomens, exposing their whitish intersegmental region and fan their wings. They release citral from their mandibular glands, an act that must be well timed relative to the progression and initiation of the raid.
Infected cicadas display some normal behavior such as sexual responsiveness, and even copulation between infected and healthy cicadas has been observed. As cicada males form large chorus centers during mating, the infection rate of males with the resting spore stage is typically higher than infected females at this stage. Conidia that fill the abdomens of infected males at this stage also alter the pitch of their mating call, resulting in them sounding smaller than they actually are to females, which may also contribute to the prevalence of higher infection rates in males than in females.
Colorized electron micrograph of soybean cyst nematode (Heterodera sp.) and egg A newly discovered parasitic tetradonematid nematode, Myrmeconema neotropicum, apparently induces fruit mimicry in the tropical ant Cephalotes atratus. Infected ants develop bright red gasters (abdomens), tend to be more sluggish, and walk with their gasters in a conspicuous elevated position. These changes likely cause frugivorous birds to confuse the infected ants for berries, and eat them. Parasite eggs passed in the bird's feces are subsequently collected by foraging C. atratus and are fed to their larvae, thus completing the lifecycle of M. neotropicum.
The coconut crab is the only species of the genus Birgus, and is related to the terrestrial hermit crabs of the genus Coenobita. It shows a number of adaptations to life on land. Like other hermit crabs, juvenile coconut crabs use empty gastropod shells for protection, but the adults develop a tough exoskeleton on their abdomens and stop carrying a shell. Coconut crabs have organs known as branchiostegal lungs, which are used instead of the vestigial gills for breathing, and after the juvenile stage they will drown if immersed in water for too long.
Some larvae, such as those of most beetles in the family Chrysomelidae, are described as eruciform, although they are short, have swollen abdomens, and have no true "prolegs" such as caterpillars have. Typically they walk freely on leaves and similar surfaces, using the "true" six legs on the three thoracic segments just behind the head. The abdomen is carried behind as a more or less swollen, hump-backed rear end. In contrast, larvae of the Cerambycidae (Longhorn beetles) are generally straight and could fairly be described as "apodous eruciform".
Big Bang performing at their Big Show concert in 2011 Big Bang has received praise for their stage presence and choreographies during live performances. Early in their career, the quintet was choreographed by Seungri and frequent collaborator Shaun Evaristo. While they once relied heavily on street dancing for their moves, they have made a transition towards other styles of choreography. One of the moves from their debut single "La La La", involving the group lifting their shirts to expose their abdomens, quickly gained popularity online and became one of the top searches on the internet.
This may be due to difference in the rewards gained by tool use: Gombe chimpanzees collect 760 ants/min compared to 180 ants/min for the Tai chimpanzees. Some chimpanzees use tools to hunt large bees (Xylocopa sp.) which make nests in dead branches on the ground or in trees. To get to the grubs and the honey, the chimpanzee first tests for the presence of adults by probing the nest entrance with a stick. If present, adult bees block the entrance with their abdomens, ready to sting.
The perception of false pregnancy has evolved over time. In the late 17th century, French obstetrician François Mauriceau believed that the enlarged abdomens of falsely pregnant patients were caused by bad air. Physicians slowly began to acknowledge other potential causes of pseudocyesis, including its origin in the mind and in the body. In 1877, a physician named Joshua Whittington Underhill observed that physical symptoms can convince a woman of pregnancy, or a “disordered brain” can convince her that ordinary abdominal pains or bowel movements are instead fetal movements.
Adult Leptophlebia marginata emerge from the aquatic nymph's final moult during daytime in early summer. The final instar nymph crawls to the surface of the water, or climbs onto an emergent plant stem, a stick or a rock, its skin splits and it emerges as a winged adult. The males fly in swarms during the day. Fertilized females have about 1200 eggs and fly over the water, dipping the tips of their abdomens in the water to lay small batches of eggs, or landing briefly on the surface to deposit their eggs.
Anomalocaris has been misidentified several times, in part due to its makeup of a mixture of mineralized and unmineralized body parts; the mouth and frontal appendage was considerably harder and more easily fossilized than the delicate body. Anomalocaris fossils were first collected in 1886 or 1888 by Richard G. McConnell of the Geological Survey of Canada. The specimens were described and named in 1892 by GSC paleontologist Joseph Frederick Whiteaves. The specimens are now known to represent isolated frontal appendages, but Whiteaves interpreted them as the abdomens of phyllocarid crustaceans.
Females are slightly larger than males, reaching a mean size of in length, whereas the males reach about 1.7 in. They are solid brown with whitish under parts, and large, white-rimmed eyes, giving them a phantom-like appearance. Breeding males and some females may have yellow throats and abdomens, and it is the only Eleutherodactylus species which exhibits sexual dimorphism in color and size. The species is characterized by large truncated discs under the frogs’ feet, and a peculiar, melodious, low voice completely different from any other coquí in Puerto Rico.
As Carol is awaiting trial in the grounds of a maximum security sanitorium, she sees one of the hippies break in and chase her through the grounds. Carol flees into the building and in trying to hide she enters a room containing a hideous experiment: four live dogs, clamped in an upright position, whimper helplessly, their abdomens sliced open and pinned with surgical clamps exposing their glistening innards and still beating hearts. Carol faints in horror. When she comes around, there is no trace of the threatening man.
The next response may be to leave the scene entirely, but especially if no line of retreat is available, their final response may also be to whirl suddenly and bite. Some tarantulas are well known to give "dry bites", i.e., they may defensively bite some animal that intrudes on their space and threatens them, but they do not pump venom into the wound. Most New World tarantulas are equipped with urticating hairs on their abdomens, and almost always throw these barbed bristles as the first line of defense.
Therizinosaurs possessed large abdomens for processing plant food, and small heads with beaks and leaf-shaped teeth. Further study of maniraptoran theropods and their relationships showed that therizinosaurs were not the only early members of this group to abandon carnivory. Several other lineages of early maniraptors show adaptations for an omnivorous diet, including seed- eating (some troodontids) and insect-eating (many avialans and alvarezsaurs). Oviraptorosaurs, ornithomimosaurs and advanced troodontids were likely omnivorous as well, and some early theropods (such as Masiakasaurus knopfleri and the spinosaurids) appear to have specialized in catching fish.
Like many members of the Thomisidae family, M. celer have the characteristic long front two pairs of legs and short back two pairs. Adults show sexual dimorphism not only in size but in color, and mature males are often darker than females and have distinctive red bands on their legs. Males also tend to have whiter abdomens with four or more pairs of brown spots that form a V-shape, starting from the mid-abdomen and terminating at end of the abdomen. The male body is also covered in noticeable dark hairs (setae).
Human women who mate with alien men die shortly after sex as their abdomens burst during the unnaturally rapid pregnancy that always follows. Most times in horror movies the typical survivor is a young girl who is still a virgin. In the film Scream, which satirizes horror movies, this rule is somewhat broken as the character Randy Meeks points out that one of the rules of horrors is to not have sex. In an intersecting scene, the film's main protagonist Sidney Prescott loses her virginity to Billy Loomis.
Tapeworm cysticercoids, possibly of the genus Hymenolepis, have been found in the abdomens of Chionea stoneana. While most likely not a parasite of snow flies, a species of nematode, similar to Rhabditis, can sometimes be found in a ringed capsule, which is called a (dauer), around the neck of adult snow flies. Immature nematodes develop inside the dauer before ultimately dispersing from it. It has been speculated that the female nematode lays this ring around the fly's neck when it emerges from the pupa and cannot yet move properly.
The physical description of male B. nobilis is less detailed than that of female adults and focuses on reproductive structures. Male B. nobilis adults have short, stout adeagi, that seem to complement the short chamber from which females' spermathecae are accessible. Their adeagi are external, and located on their abdomens, and only males of B. nobilis have yellow plumage on their heads. The presence of this plumage may hint at the existence of male competition for female mates, as throughout animal species, bright plumage on males is often involved in mating rituals.
Qongqothwane is a traditional song of the Xhosa people of South Africa. It is sung at weddings to bring good fortune. In the western world it is mainly known as The Click Song, a nickname given to the song by European colonials who could not pronounce its Xhosa title, which has many click consonants in it. The Xhosa title literally means "knock-knock beetle", which is a popular name for various species of darkling beetles that make a distinctive knocking sound by tapping their abdomens on the ground.
For the average home butterfly garden, this scenario will only add more OE to the local population. After the caterpillar becomes a butterfly, the toxins shift to different parts of the body. Since many birds attack the wings of the butterfly, having three times the cardiac glycosides in the wings leaves predators with a very foul taste and may prevent them from ever ingesting the body of the butterfly. In order to combat predators that remove the wings only to ingest the abdomen, monarchs keep the most potent cardiac glycosides in their abdomens.
Itsines found work at a women's gym in Adelaide. Itsines came to believe that most women seek three specific outcomes from training: smaller inner thighs, flatter abdomens, and more toned arms, while also being concerned about becoming too bulky. She also started training her sister's friends who wanted to improve their fitness so they could play Netball on their high school team, focusing on building core strength and powerful legs. She lectured them on nutrition, and asked them to take before-and-after photos of themselves to track their progress.
Dolomedes spiders are covered all over in short, velvety hairs which are unwettable (hydrophobic). This allows them to use surface tension to stand or run on the water, like pond skaters. They can also climb beneath the water, and then air becomes trapped in the body hairs and forms a thin film over the whole surface of the body and legs, giving them the appearance of fine polished silver. Like other spiders, Dolomedes breathe with book lungs beneath their abdomens, and these open into the air film, allowing the spiders to breathe while submerged.
Fish that become infected experience hemorrhaging of their internal organs, skin, and muscle. Some fish show no external symptoms, but others show signs of infection that include bulging eyes, bloated abdomens, bruised-looking reddish tints to the eyes, skin, gills and fins. Some infected fish have open sores that may look like the lesions from other diseases or from lamprey attacks.01/25 - VHS disease has entered Great Lakes There may also be a nervous form of the disease where fish are constantly flashing and showing abnormal behaviour.
Carniolan honey bees are about the same size as the Italian honey bee, but they are physically distinguished by their generally dusky brown-grey color that is relieved by stripes of a subdued lighter brown color. Their chitin is dark, but it is possible to find lighter colored or brown colored rings and dots on their bodies. They are also known as the "grey bee". Carnica bee on Hylotelephium 'Herbstfreude' with pollen basket Carnica bee on Hylotelephium 'Herbstfreude' Carniolan bees are nearly as big and long as the Western European black bees, though their abdomens are much slimmer.
This type of polyandry has been demonstrated by analyzing the genetic composition of Gulf pipefish, Sygnathus scovelli and straightnose pipefish, Nerophis ophidion, which shows that males only mate once during their pregnancy, whereas females mate multiple times. This extreme form of polyandry indicates that this species has a much stronger intensity of sexual selection on females than on males, in which females tend to be larger and more adorned than males. Evidence for stronger sexual selection in females in Gulf pipefish, Syngnathus scovelli, include having secondary sexual characteristics, such as longer abdomens and stripes that are not found in males.
Females' chelicerae are dark orange- brown and decorated with sparse white hairs, which form bands near the carapaces. The abdomens of females are mottled brown and black, and bear hairs of gold, white and black, and there are tufts consisting of brown hairs tipped with white. The carapaces of males are orange-brown, slightly lighter around the eyes, and have brown-black hairs lying on the surface but with a white wedge-shape stripe from the highest point down to the back, and white bands just above the legs. Males' chelicerae are also orange-brown with brown-black markings.
If she was receptive the male then see-sawed his front legs over her several times and then mounted and twisted her abdomen before inserting one palp into her epigynum, repeating with a second palp on the other side. Males would often repeat mating several times until the female started to move. Male-male agonistic display initially began like courtship, but within seconds the males would unsheathe their fangs and move toward each other with abdomens cocked and front legs spread. If the males were of similar size they would usually lock chelicerae and touch spread front legs, trying to bite.
Males in certain species of spiders often employ drastic methods to be paternally successful. Monogyny in spiders culminates in extreme traits, such as dramatic male self-sacrifice and emasculation of the male by the female during copulation. Since males only mate with one female in a monogynous setting, each individual male must do whatever it takes to increase his particular paternity success, even if it means sacrificing himself. Male redback spiders twist their abdomens onto the fangs of their mates during copulation and, if cannibalized (65% of matings), increase their paternity relative to males that are not cannibalized.
Members of the Aphididae are soft-bodied, pear-shaped insects called aphids, as are other members of the superfamily Aphidoidea. Most of them have a pair of little tubes, called cornicles, projecting dorsally from the posterior of their abdomens. The cornicles have been variously interpreted in the past, either as organs of excretion, or for the production of honeydew, but in fact their only confirmed function to date is that they produce fatty alarm pheromones when the insects are attacked by predators. When wings are present they occur only on particular morphs called "alates", and wingless morphs are said to be "apterous".
In a study of six nests of Polistes carnifex, in three cells there was an additional egg instead of the usual one, but these eggs appeared to be of P. carnifex. The author of this study found no evidence of parasitism, however, the wasps are indeed parasitized by strepsipteran insects in the genus Xenos. These obligate parasites infect the developing wasp larvae in the nest and are present within the abdomens of female wasps when they hatch out. Here they remain until they thrust through the cuticle and pupate (males) or release infective first-instar larvae onto flowers (females).
The adult N. lecontei has membranous wings and a broad waist and is between long, with the males being somewhat smaller than the females. Males have feathery antennae while females have serrated ones with nineteen segments. Males are entirely black and are more slender than the robust females, which have reddish-brown heads and thorax, and mainly black abdomens, sometimes with white on the sides. The larvae resemble the caterpillars of lepidopterans; young larvae are whitish with brown heads while older larvae are yellowish-green with up to eight longitudinal rows of black spots, and brown heads.
Ventral view of B. terrestris B. terrestris are pollen-storing bees that generally feed and forage on nectar and pollen. The queen is between 20 and 22 mm long, males range from 14 to 16 mm, and workers from 11 to 17 mm. Workers have white-ended abdomens, and look just like workers of the white-tailed bumblebee, B. lucorum, a close relative, apart from the yellowish bands of B. terrestris being darker in direct comparison. The queens of B. terrestris have the namesake buff-white abdomen tip ("tail"); this area is white as in the workers in B. lucorum.
Young Grammostola rosea showing patch of urticating hairs, reflecting a camera flash Urticating hairs or urticating bristles are one of the primary defense mechanisms used by numerous plants, almost all New World tarantulas, and various lepidopteran caterpillars. Urtica is Latin for "nettle" (stinging nettles are in the genus Urtica), and bristles that urticate are characteristic of this type of plant, and many other plants in several families. This term also refers to certain types of barbed bristles that cover the dorsal and posterior surface of a tarantula's or caterpillar's abdomen. Many tarantula species eject bristles from their abdomens, directing them toward potential attackers.
Dr. Phil featured women on his talk show who believed they had been pregnant for years with a cryptic pregnancy. Despite negative urine and blood tests, and medical imaging of their abdomens showing no pregnancy, the women persisted in their belief they were pregnant, including one who had had a tubal ligation in her early 20's. Dr. Thais Aliabadi was the expert guest on the show and explained that many women claim to have a cryptic pregnancy to explain physical symptoms they associate with pregnancy, such as weight gain in the abdomen, mood swings, sore breasts and food cravings.
Confronted by this, predators like scorpions, centipedes, hunting wasps and even birds, often give up and go away. However, this defense has been breached by certain parasitic wasps that can maneuver their paper-thin abdomens and long, slender egg-laying tubes (ovipositors) down along the grooves on the spider's abdomen, allowing their eggs to be laid on the softer cuticle at the front of the abdomen. The wasp larva that emerges is difficult for the spider to dislodge from that area and it can safely start devouring its victim alive. The thick cuticle also prevent against water loss through evaporation.
The blood is digested over time, serving as a source of protein for the production of eggs, which gradually fill the abdomen. Anopheles mosquitoes can be distinguished from other mosquitoes by the palps, which are as long as the proboscis, and by the presence of discrete blocks of black and white scales on the wings. Adults can also be identified by their typical resting position: males and females rest with their abdomens sticking up in the air rather than parallel to the surface on which they are resting. Adult mosquitoes usually mate within a few days after emerging from the pupal stage.
Female Gasteracantha interrupta spiders have hardened, shell-like abdomens that are black and white in color and armed with six spines. Friedrich Dahl described this species in 1914 based on five specimens from Sulawesi and Lombok. Dahl distinguished this species from another black-and-white species, the wide-ranging Gasteracantha kuhli, based on a plain white central area on the dorsal side of the abdomen and details of the sigilla. In particular, Dahl noted that the outermost sigilla in the anterior row are very close to the anterior spines, instead of partway between the anterior and median spines.
This claim is supported by the fact that N. deltocephalinicola's closest bacterial relative is Zinderia insecticola, which plays the same role for spittlebugs as N. deltocephalinicola does in leafhoppers. Leafhoppers return the favor by providing shelter in the form of a specialized organ in their abdominal cavity called a bacteriome, which they have on both sides of their abdomens. Many types of bacteria can reside in these organs, though the bacteria are completely separated from each other and reside in different sections of the bacteriome. N. deltocephalinicola is an obligate endosymbiont—it cannot thrive without being in a leafhopper.
Austracantha minax is most commonly known as "jewel spiders" due to their body colouration. This may sometimes be specified further as "Australian jewel spiders" due to the common name being shared with the unrelated North American jewel spider Araneus gemmoides, as well as the widespread jewel box spider Gasteracantha cancriformis. In some parts of Australia they are also widely known as "Christmas spiders" because they are most numerous during the summer months (December and January). Other common names for the species include "six-spined spiders" and "spiny spiders" in reference to the spine-like projections on their abdomens.
To make balance easier, they can move their heavy abdomens with a ball joint. Standard Tachikoma equipment includes a 7.62×51mm light machine gun mounted in the right arm, a secondary weapon hardpoint in the "snout" (a 50 mm grenade launcher, capable of launching both explosive and gas grenades which can be replaced by a six-barrelled 12.7×99mm Gatling gun), a universal cybernetic connector on an extensible, prehensile cable in the left arm, liquid wires that can be used for grappling, rappelling or for restraining purposes and a built-in thermoptic camouflage system.Stand Alone Complex Visual Book, Page 29.
Zora is a genus of spiders in the family Miturgidae, subfamily Zorinae, consisting of small to medium entelegyne, ecribellate spiders. They can be identified as they have two claws with claw tufts, distinct longitudinal bands on the cephalothorax, 4-2-2 arrangement of the eight eyes and long overlapping spines on the first two tibiae and metatarsi. Their abdomens show distinct colour patterns which may be useful in identification to species. There are 17 species in the genus which have a Holarctic distribution, mostly in Europe and the Middle East but with two species in North America.
The outdoor activity is mainly restricted to the hotter summer months, when the ants are active during the heat of the day. Foragers usually begin their activity at soil surface temperatures of about 50 °C and continue to forage when soil temperatures are above 70 °C. They forage solitarily for food such as dead insects, seeds, and sugary plant exudates and are well known for their ability to store liquids in the abdomens of specialized workers, the so-called repletes or "honey pots", hence their common name "red honey ant" (the genus name Melophorus means "honey carrier").
Weaver ants of this species are important parts of the ecosystem in tree canopies in humid tropical regions. The nests of this species are constructed by the workers, with leaves being woven together and secured by silk produced by the larvae. First a row of ants line up along the edge of a green leaf and, grasping a nearby leaf, pull the two leaves together, edge to edge. Other workers on the far side of the leaves, each carrying a larva in its mouth, apply the tips of the abdomens of the larvae to each leaf edge in turn.
Rather than telling the patient to "relax", which can trigger strong emotions for patients who are survivors of assault, patients can be told to breathe slowly and deeply into their abdomens, which is a more instructive way of describing how to relax the pelvic muscles. Careful preparation is helpful for an efficient and comfortable exam. Prior to asking the patient to position themselves on the exam table, the examiner should collect all the instruments needed for the exam and any planned procedures, including the speculum, light source, lubricant, gloves, drapes, and specimen collection media. Warming the speculum with warm tap water can also increase comfort.
Crucially, however, Berthold reprised an experiment that he knew John Hunter had tried with unclear results before 1771 with hens. He transplanted testes back into the abdomens of two of the castrated birds but in a different location; the remasculated birds progressed to develop secondary sexual characteristics, indicating that the testes functioned effectively normally. Upon autopsy, he found that the transplanted testes had grown a new vasculature but no other bodily connection: this finally demonstrated that whatever was controlling the secondary characteristics was transported from the testes via the bloodstream. The prevailing theory, that sexual characteristics were mediated via the nervous system, was thus disproved.
They make their nests in old Protea flowers,Ispot dead, hollow branches, and under tree bark, also making nests constructed of well-chewed vegetable matter with the consistency of papier-mâché. The outer walls of these nests are blackened by the salivary secretions, and are thin, with the interior divided into irregular, connected cells, like a coarse sponge. These more or less spherical nests, ranging in diameter from 10–30 cm, are built in a fork or among the branches, some of the branches passing through the nest. Workers are glossy black and 3–5 mm long while the larger queen is about 8 mm long, both having heart-shaped abdomens.
The legs of both sexes are unusually long and slender, and those of male's are orange-brown with darker markings while those of females are light yellow with blackish markings. In both sexes the final two segment of each leg has no other decorations, but the other segments in both sexes have brownish hairs and many robust spines, and those of males also scattered white tufts. The palps of both sexes have pale yellow hairs and white fringes. All species of the genus Portia have elastic abdomens, so that those of both sexes can become almost spherical when well fed, and females' can stretch as much when producing eggs.
Parasitic castrators partly or completely destroy their host's ability to reproduce, diverting the energy that would have gone into reproduction into host and parasite growth, sometimes causing gigantism in the host. The host's other systems remain intact, allowing it to survive and to sustain the parasite. Parasitic crustaceans such as those in the specialised barnacle genus Sacculina specifically cause damage to the gonads of their many species of host crabs. In the case of Sacculina, the testes of over two-thirds of their crab hosts degenerate sufficiently for these male crabs to develop female secondary sex characteristics such as broader abdomens, smaller claws and egg-grasping appendages.
Because of its layered structure, the tent is thermally heterogeneous, and the caterpillars can adjust their temperature by moving from layer to layer. They may also aggregate on the outside of the shaded side of the tent and hang from the tips of their abdomens to enhance convective heat loss and cooling. As has been shown for some other caterpillars, eastern tent caterpillars are capable of generating a small amount of metabolic heat while they digest their meals. When recently fed caterpillars pack tightly together, the temperature in the interior of the mass may be several degrees above ambient temperature even in the absence of a radiant heat source.
Bands of feral horses, commonly known as Chincoteague ponies or as Assateague horses, freely roam on Assateague Island. Although local legend claims that the horses are descendants of animals that survived a shipwreck on the coast, it is more likely that the horses are descendants of domestic horses confined on the island by local residents in lieu of fencing them in on the mainland, where fences were taxed. The salty low-nutrient diet of saltmarsh grasses has resulted in the horses' short stature and bloated abdomens. Horses at Assateague Island National Seashore in August 2015 Two herds are kept separate by a fence at the Maryland-Virginia border.
Irrumatio is a form of oral sex where a man thrusts his penis into someone else's mouth, in contrast to fellatio where the penis is being actively orally excited by a fellator. The difference lies mainly in which party takes the active part. By extension, irrumatio can also refer to the sexual technique of thrusting the penis between the thighs of a partner (intercrural sex), or between the abdomens of two men. In the ancient Roman sexual vocabulary, irrumatio is strictly a form of oral rape (os impurum), in which a man forces his penis into someone else's mouth, almost always that of another man.
Chrysidines are distinguished from the members of other subfamilies in that most have flattened or concave lower abdomens and can curl into a defensive ball when attacked by a potential host, a process known as conglobation. Protected by hard chitin in this position, they are expelled from the nest without injury and can search for a less hostile host. Fleas can jump vertically up to 18 cm and horizontally up to 33 cm; however, although this form of locomotion is initiated by the flea, it has little control of the jump—they always jump in the same direction, with very little variation in the trajectory between individual jumps.
The behavior and process of nest building consists of foragers delivering the paper material to the construction place; the foundress moving over the area and sometimes exhibiting wagging and/or trapping movements with its abdomen; the foundress grasping the entire amount of materials or some part of it; and the construction of the petiole, cell base, or cell wall. The foundresses wag their abdomens while keeping the batch of pulp in their mandibles. They continue this wagging movement until they find a suitable place to apply the pulp. The foundress may sometimes take the nest material (partly or completely) from the foragers who brought it to the nest.
Male blue ringtail (Austrolestes annulosus), a damselfly (Zygoptera: Lestidae) Dragonfly (top) and damselfly (bottom) wing shape and venation These insects characteristically have large rounded heads covered mostly by well-developed, compound eyes, legs that facilitate catching prey (other insects) in flight, two pairs of long, transparent wings that move independently, and elongated abdomens. They have three ocelli and short antennae. The mouthparts are on the underside of the head and include simple chewing mandibles in the adult. Flight in the Odonata is direct, with flight muscles attaching directly to the wings; rather than indirect, with flight muscles attaching to the thorax, as is found in the Neoptera.
Formica rufa, also known as the red wood ant, southern wood ant, or horse ant, is a boreal member of the Formica rufa group of ants, and is the type species for that group. It is native to Europe and Anatolia, but is also found in North America, in both coniferous and broad-leaf broken woodland and parkland. Workers are colored red and brownish-black, with a dorsal dark patch on the head and promensonotum, and are polymorphic, measuring 4.5–9 mm in length. They have large mandibles, and like many other ant species, they are able to spray formic acid from their abdomens as a defence.
The Steatoda bipunctata is similar in shape to the Black Widow spider of the genus Latrodectus and can thus be mistaken for it, although its bite is significantly less dangerous to humans. For this reason, species of the genus Steatoda are commonly called 'False Widows'. The abdomens of both sexes are bulbous and brownish in coloration, typically with a broken pale line down the center and another pale line across the anterior portion of the abdomen. The apodemes (places of muscle attachment) on the dorsal side of the abdomen look like pairs of dark dimples and presumably give the spider its Latin name bi- (two) and -punctata (spots).
When the male larva reaches the third-instar developmental stage, it forms a delicate white cocoon and transforms into a pupa in early June. In late June or early July, females, which are neotenous and retain their larval form, re-emerge from the ground and slowly climb to the top of the host plant, where they wait until winged adult males, with characteristic plumes at the end of their abdomens, leave the cocoons and join them a few days later. Male imagines (adult insects) do not feed and die shortly after mating, while their female counterparts return underground to lay eggs. After oviposition, the female insects shrink and die.
At that time the picadors' horses were often gored by bulls, and the unpleasant spectacle was aggravated when, in the same arena, they sewed the horses' intestines back into their abdomens so that the picadors could continue to make use of them. She collaborated with Hildegart Rodriguez and Irene Falcón at the Marxist feminist publishing house Nosotras. She prefaced Federica Montseny's book Escrits politic and also Las reivindicaciones femeninas by in 1927. She took care to publish the final editions of the works of Rosario de Acuña, a famous writer and companion of her brother Carlos de Lamo Jiménez, of whom she became a good friend.
Abdomens () are an Ultras group, established in 1985, who support the Macedonian sports clubs from Bitola that compete under the Pelister banner, mainly FK Pelister in football and RK Pelister in handball. The group was founded in 1985 when a caravan of 15 buses traveled to support RK Pelister who was playing against Partizan Bjelovar in a handball relegation play-off match. At that time they used the name BMČM - Bitolčani, Motorcyclists, Čkembari, Macedonians (македонски: БМЧМ - Битолчани, Мотокари, Чкембари, Македонци) later shortened to just Čkembari. Soon after, the first green and white banners were created that read: "Hell Boys" (македонски: Пеколни момци) and "Green Conquerors" (македонски: Зелени освојувачи) which started organized support for Pelister at every match.
Neel Shah is an American physician, Harvard University assistant professor, and founder of the nonprofit organizations Costs of Care and March for Moms. Shah proposed an ethical framework for medicine that includes financial harm to patients under the "do no harm" principle of medical ethics. He participated in a project aiming to collect essays about instances in which inattention to costs has harmed patients — emulating the patient-safety movement's use of anecdotes about sponges left in abdomens or amputations of the wrong limb. Shah was featured in a "Doctor and Patient" New York Times column by Pauline Chen for creating the Teaching Value Project, aimed at educating doctors about how their decisions impact what patients pay for care.

The book was negatively reviewed in medical journals for not providing reliable evidence for its claims. A review in the Journal of Cancer Research suggested that the "publication of such a book does a great deal of harm because it misleads those who have no real knowledge and encourages charlatanry, of which there is already too much." A review in the Nature journal commented that "In our opinion the book will do much more harm than good, as it can only have a deleterious action and make people concern themselves with morbid symptoms in their abdomens." A review in the Journal of the American Medical Association concluded that the book is a "pernicious and harmful piece of literature".
Smaller amounts of contaminated water with lower concentrations caesium was found in a tunnel near reactor no.1. How the water could accumulate at these places was under examination.The Mainichi Daily news (13 January 2012) 300 tons of tainted water found near No. 3 unit at Fukushima plant In a study that began two months after the earthquake and tsunami, mutant butterflies were found and are considered a possible reaction to the Fukushima nuclear disaster. Some of the butterflies had abnormalities in their legs, antennae, and abdomens, and dents in their eyes. In the morning of 18 July 2013 at 8:20 a.m. (2320 GMT) small amounts of steam escaped from the reactor building.
Coconut crabs mate frequently and quickly on dry land in the period from May to September, especially between early June and late August. Males have spermatophores and deposit a mass of spermatophores on the abdomens of the females; the abdomen opens at the base of the third pereiopods, and fertilisation is thought to occur on the external surface of the abdomen as the eggs pass through the spermatophore mass. In: Brown & Fielder (1991) The extrusion of eggs occurs on land in crevices or burrows near the shore. Shortly thereafter, the female lays her eggs and glues them to the underside of her abdomen, carrying the fertilised eggs underneath her body for a few months.
More brain transplant experiments in Hyalophora cecropia and Antheraea pernyi showed that both entrained and free-running eclosion rhythms can be rescued in debrained moths that have had brains transplanted into their abdomens. These restored eclosion rhythms in the debrained moths matched in phase angle with the eclosion rhythms observed in the donor moths prior to brain transplantation. These results confirmed Truman's previous findings that the circadian clock is located within the brain and that the factor mediating eclosion behavior is hormonal. Similar experiments focusing on the role of the circadian clock in regulating flight rhythms confirmed that extraretinal photoreceptors in the brain are responsible for entraining a brain-based circadian clock.
Each female will do this up to three times in her life, sometimes more than one at a time. Some females get lost returning to their brood and start caring for another individual clutch as they are not able to distinguish between their own young and another’s. The young will go on to dig their own nest for molting taking anywhere from 4 to 50 days to reach the next instar, repeating to a total of 6 instars before adulthood. Once adults, the individuals will live for only 2–3 months, and begin courting immediately. This is done by a feeling of antennae, and mutual grabbing of each other’s abdomens with their forceps until copulation occurs.
Ctenocephalides felis felis The cat flea belongs to the insect order Siphonaptera which in its adult stage is an obligatory hematophage. Adults of both sexes range from 1–2 mm long and are usually a reddish-brown colour, although the abdomens of gravid females often swell with eggs causing them to appear banded in cream and dark brown. Like all fleas, the cat flea is compressed laterally allowing it to slip between the sometimes dense hairs of its host just above the top layer of the skin, resulting in an extremely thin insect that may be difficult to observe even if the host's coat is pure white. The cat flea affects both the cat and the dog worldwide.
Cuckoo Wasp on pine needle, North Carolina Piedmont Members of the largest subfamily, Chrysidinae, are the most familiar; they are generally kleptoparasites, laying their eggs in host nests, where their larvae consume the host egg or larva while it is still young, then the food provided by the host for its own juvenile. Chrysidines are distinguished from the members of other subfamilies in that most have flattened or concave lower abdomens and can curl into a defensive ball when attacked by a potential host, in the manner of a pill bug. Members of the other subfamilies are parasitoids, of either sawflies or walking sticks, cannot fold up into a ball. Chrysidids are always solitary.
Females have a bright orange colouring that attracts the male and also perform a series of fluttering wing movements that make the insect appear to "dance" and make the openings on their abdomens to swell in order to attract a male. It is also interesting to note that there is experimental evidence that implies the female may also release pheromones that attract the male; this is an instance of chemical display behaviour that plays a large role in animal communication. This auditory courtship behavior is also seen in fruit flies like A. suspensa when they perform calling and pre-copulatory songs before mating. Both of these sounds are created by rapid flapping of the males wings.
This sense helps them protect themselves from harm in the wild but in a household situation it helps them sense when their owner may be near and might be going to pick them up. Hamsters have scent glands on their flanks (and abdomens in Chinese and dwarf hamsters) which they rub against the substrate, leaving a scent trail. Hamsters also use their sense of smell to distinguish between the sexes, and to locate food. Mother hamsters can also use their sense of smell to find her own babies and find out which ones aren't hers, the scent glands can also be used to mark their territories such as their babies or their mate.
Bees in the outer layer thrust their abdomens 90° in an upward direction and shake them in a synchronous way. This may be accompanied by stroking of the wings. The signal is transmitted to nearby workers that also adopt the posture, thus creating a visible — and audible — "ripple" effect across the face of the comb, in an almost identical manner to an audience wave at a crowded stadium. These wave-like patterns repel wasps that get too close to the nests of these bees and serve to confuse the wasp. In turn, the wasp cannot fixate on capturing one bee or getting food from the bees’ nest, so the wasp will seek to find easier prey and leave this nest alone.
Some difference in color occurs between the animals found on different islands, ranging from orange-red to purplish blue; in most regions, blue is the predominant color, but in some places, including the Seychelles, most individuals are red. Although B. latro is a derived type of hermit crab, only the juveniles use salvaged snail shells to protect their soft abdomens, and adolescents sometimes use broken coconut shells for that purpose. Unlike other hermit crabs, the adult coconut crabs do not carry shells, but instead harden their abdominal terga by depositing chitin and chalk. Not being constrained by the physical confines of living in a shell allows this species to grow much larger than other hermit crabs in the family Coenobitidae.
V. pellucens is about 13–17 mm in length, with a wing length about 10–15.5 mm.CommansterStuart Ball, S. G. Ball, Roger Morris Britain's Hoverflies: An Introduction to the Hoverflies of Britain These hoverflies have a broad, mainly black body, but the front part of their abdomens have a broad, yellow band, giving them the appearance of a bee or wasp. Their two wings are transparent, as with most flies, but the leading edge is amber, with a brown patch on each wing. The mimicry of bees or wasps in shape and colouration is shown by other hoverflies, which is thought to protect against falling prey to birds and other insectivores that avoid eating true wasps because of their stings.
In 1978, Simon Conway Morris recognized that the mouthparts of Laggania were Peytoia-like, but he interpreted this as evidence that it was a composite fossil made up of a Peytoia jellyfish and a sponge. In 1979, Derek Briggs recognized that the fossils of Anomalocaris were appendages, not abdomens, but interpreted them as walking legs. It was not until 1985 that the true nature of the fossils of Anomalocaris, Laggania, and Peytoia was recognized, and they were all assigned to a single genus, Anomalocaris. Subsequently it was recognized that Anomalocaris was a distinct form from the other two, resulting in a split into two genera, the latter of which was variously named Laggania and Peytoia until it was determined that Peytoia had priority.
Aggression is commonly seen between conspecifics of all halictid bees; especially between usurper females, drawn out fights can occur that last for nearly a half-hour and result in damage to or loss of limbs and body parts. Guard bees of the L. malachurum species, which are workers that defend the nest, also demonstrate antagonistic behavior toward non-nestmate conspecifics, by orienting their stingers toward the intruders or blocking the entrance to the nest with their abdomens. They are able to discriminate between non-nestmates and nestmates, which they allow to pass with ease. Foragers, though, are either unable to discriminate between nestmate and non-nestmate conspecifics or are uninterested in pursuing aggression against non-nestmate conspecifics, so exhibit high levels of tolerance toward all conspecifics.
M. celer individuals engage in courtship behavior to indicate receptiveness and willingness to copulate to one another. When recognizing a potential female mate, males vibrate their abdomens and slowly approach the female, gesturing with the front two pairs of legs and the pedipalps. Then, the male touches the female with the same front two pairs of legs, and if the female is receptive, she raises her legs and suspends herself in silk threads to indicate her receptivity to the male. After the female has accepted the male in this manner, the male climbs over the back (dorsal side) of the female and positions his head and thorax, collectively the prosoma, near the female's epigyne so that his pedipalps are close to it.
The investigative committee interviewed the hospital officials and concluded that injuries like this may happen due to the efforts of doctors, who are trying to position the unborn fetus for a delivery. On March 15 and 21, Medical examinations were conducted on 32 of the women, confirmed presence of abrasions on their chests and abdomens, and three of the unmarried women had torn hymens. The team concluded that "such a delayed medical examination proves nothing" and that such abrasions are commonly found among villagers in Kashmir. The hymen can be torn due to natural factors, injury or pre marital sex In stark contrast of the purported allegations of abuses, these investigations concluded the allegations themselves are "grossly exaggerated or invented".
Two different feeding groups were established in M. bellicosus based on examining the gut contents of workers in foraging sites, the fungus comb and queen cell. These two groups differed in abdomen coloration, with the majority of workers having a dark brown abdomen that was correlated with feeding on the fungus comb, and a smaller amount having a reddish-brown abdomen caused by feeding on plant litter. There is a division of food intake between the major and minor workers, based on the fact that most of the termites with reddish-brown abdomens, caused by consuming plant litter, were major workers. Because the fungus comb is built with the feces of consumed plant litter, major workers are dominant in fungus comb construction and are also the dominant worker caste for food processing.
The Epeolus larva then consumes the egg of the host bee and then feeds on the pollen the Colletes bee provisioned the cell with for her offspring. Epeolus bees may be rather obvious and easily observed in the vicinity of the nesting aggregations of their hosts and often use the same flowers to feed on. Colletes bees line their nesting cells with a cellophane like covering which they exude from the Dufour's gland to protect the cell from moisture and fungal infection, female Epeolus bees have spines on the end of their abdomens which they use to pierce u-shaped holes in this covering so that she can oviposit between its layers, she also secretes a small amount of glue so that the egg adheres to the cell.
Size comparison between N. mckinleyi and N. graffami The genus Nothronychus can be distinguished from other therizinosaur taxa based on the distinctly subcircular obturator process; an elongated obturator foramen towards the bottom; the contact area between pubis and ischium is restricted to the upper half of the obturator projection; deep cut between towards the bottom facet of the obturator process and frontal ischial shaft. Both species, N. mckinleyi and N. graffami, were similar in size with equal sized humeri (upper arm) ( and respectively), covering in length and about in weight. Nothronychus were ponderous animals with large "pot-bellied" abdomens, long necks, and stocky hindlimbs with four-toed feet. The arms were relatively large with dexterous hands equipped with up to long curved and sharply-pointed claws on their fingers.
Gregarious aggregation of bogong moths during aestivation During the spring migration, bogong moths gregariously aggregate with densities reaching 17,000 moths per square metre (10.8 square feet) within caves, crevices, and other areas hidden from the sunlight. The lack of light and relatively constant temperature and humidity makes these spots favourable during aestivation. The first moths that arrive occupy the deepest and darkest locations, using their fore tarsi to grip onto the rock faces, and aggregations form around these initial areas, with moths arriving later settling for less ideal areas with more sunlight, higher temperatures, and decreased humidity. To diminish the amount of light that reaches their light- sensitive eyes, later moths push themselves underneath the wings and abdomens of moths that arrived earlier and place their hind legs on top of the moths beneath them.
The preservation by some Starčevo-Criş communities of painted pottery, in addition to the Vinča elements, engendered in the area of the eastern arch of the Western Carpathians the Cluj-Cheile–Turzii-Lumea Nouă-Iclod cultural complex. This complex represents the substratum for the emergence of the Petreşti culture. Long term research at Iclod has demonstrated that this station possessed a complex fortification system built during the Iclod, Phase I, still in use for some time in the Iclod II phase, eventually abandoned when the settlement expanded. It is in the same spot that research has been carried in two inhumation necropoles, where the dead were laid on their backs hands across their chests or abdomens or along their bodies; the bodies were oriented east- west, their heads facing east.
There can be difficulty in identifying M. celer from a male alone; males of M. celer appear quite similar to males of Mecaphesa dubia and Mecaphesa rothi, and due to natural variation in physical traits that can occur within a single species, distinguishing between these three species can be quite uncertain. Female M. celer, meanwhile, are more distinct from other species. They tend to be yellow in color and have large, round abdomens much larger than their heads, unlike the male, whose abdomen and head are roughly equal in size. Females can actually vary in their coloration, with one variant being a bright, solid yellow with barely any brown spotting, another variant being yellow with reddish-brown streaking on the abdomen, and a third variant being completely white with dull brown streaking on the abdomen.
Spock advocated that infants should not be placed on their back when sleeping, commenting in his 1958 edition that "if [an infant] vomits, he's more likely to choke on the vomitus." This advice was extremely influential on health-care providers, with nearly unanimous support through to the 1990s. Later empirical studies, however, found that there is a significantly increased risk of sudden infant death syndrome (SIDS) associated with infants sleeping on their abdomens. Advocates of evidence-based medicine have used this as an example of the importance of basing health-care recommendations on statistical evidence, with one researcher estimating that as many as 50,000 infant deaths in Europe, Australia, and the US could have been prevented had this advice been altered by 1970, when such evidence became available.
Both male and female gulf fritillaries possess certain defensive glands located on their abdomens that serve as a defense mechanism against predators, especially avian predators such as birds. When the butterflies sense danger in the area or are suddenly disturbed, these glands emit a distinct and obvious odor which is composed of several different types of chemicals, such as 6-methyl-5-hepten-2-one and hexadecyl acetate. The summation of these chemical compounds released from the glands leads to birds preferentially avoiding the gulf fritillaries in favor of other prey. In some cases, gulf fritillaries can sometimes be subjected to competition and fighting from other butterfly species, such as Heliconius charithonia vazquezae and Dryas iulia moderata when those species have breeding populations in similar areas and within the same geographic range.
In the popular imagination of the mid-19th century, "poor white trash" were a "curious" breed of degenerate, gaunt, haggard people who suffered from numerous physical and social defects. They were dirty, callow, ragged, cadaverous, leathery, and emaciated, and had feeble children with distended abdomens who were wrinkled and withered and looked aged beyond their physical years, so that even 10-year-olds' "countenances are stupid and heavy and they often become dropsical and loathsome to sight," according to a New Hampshire schoolteacher. The skin of a poor white Southerner had a "ghastly yellowish-white" tinge to it, like "yellow parchment", and was waxy looking, or they were so white they almost appeared to be albinos. They were listless and slothful, did not properly care for their children, and were addicted to alcohol.
Although it has hairy legs, this tarantula is an Old World species and does not have urticating hairs on its abdomen. (Urticating hairs are hairs found in most new world species (those from North and South America) that can be shed in defence, they are barbed and may cause severe itching.) It also has a leg span which may reach . This tarantula, in common with the rest of the family, has downward- facing, parallel fangs, used like pickaxes rather than pincers. Adult males have smaller abdomens than females. Male pedipalps are club shaped, but it may take up to 4 years for differences between male and female to show, since the average male lifespan is about 4 years and the leg span of the male is roughly 5”.
Females fly onto the site, and courtships take place in a bewildering variety. The female may fly to one of the perched males, or to a perch of her own choosing; she may be pursued on the way by one or more males, or males may fly to her after she perches. Or she may perform a mutual courtship dance with a flying male. Or a male and female, both perched, may approach each other by progressive changes of perch. Coupling is acrobatic and “front to back”: the pair hang with the male in front and the female behind, facing the same way, and by a corkscrew action of the abdomens finish with the female hanging vertically by her front feet, and the male dangling upside down and held to her only by the grip of the genitalia.
In the process of this revision, Whittington and his students Simon Conway Morris and Derek Briggs would discover the true nature of Anomalocaris and its relatives, but not without contributing to the history of misinterpretations first. In 1978, Conway Morris recognized that the mouthparts of Laggania were identical to Peytoia, but concluded that Laggania was a composite fossil made up of Peytoia and the sponge Corralio undulata. In 1979, Briggs recognized that the fossils of Anomalocaris were appendages, not abdomens, and proposed that they were the walking legs of a giant arthropod, and that the feeding appendage Walcott had assigned to Sidneyia was the feeding appendage of Anomalocaris. Later, while clearing what he thought was an unrelated specimen, Harry B. Whittington removed a layer of covering stone to discover the unequivocally connected frontal appendage thought to be a shrimp tail and mouth thought to be a jellyfish.
A worker bee's waggle dance involves running through a small figure-eight pattern: a waggle run (aka waggle phase) followed by a turn to the right to circle back to the starting point (aka return phase), another waggle run, followed by a turn and circle to the left, and so on in a regular alternation between right and left turns after waggle runs. Waggle-dancing bees produce and release two alkanes, tricosane and pentacosane, and two alkenes, (Z)-9-tricosene and (Z)-9-pentacosene, onto their abdomens and into the air. The direction and duration of waggle runs are closely correlated with the direction and distance of the resource being advertised by the dancing bee. In an experiment with capture and relocation of bees exposed to a waggle dance the bees followed the path that would have taken them to an experimental feeder had they not been displaced.
Tankinis are suggested as an option for women who had gone through mastectomy, i.e. removal of one or both breasts by surgery,Carolyn M. Kaelin & Francesca Coltrera, Living Through Breast Cancer, page 133, McGraw-Hill Professional, 2005, modest bust sizes,Lloyd Boston, Before You Put That On: 365 Daily Style Tips for Her, page 161, Atria Books, 2005, and long- torsos.June Ambrose, Richard Buskin & Aimee Levy, Effortless Style, page 51, Simon Spotlight Entertainment, 2006, For women who don't have washboard abs, Betts commented, "If you don't feel comfortable wearing a bikini, the tankini's an option that's sort of in between." In Think & Date Like a Man, fashion writer April Masini suggests wearing a tankini for women with smaller breasts and less-than-toned abdomens as the most flattering choice of beachwear, with the right amount of coverage along with the feeling of a two- piece suit.
When hovering around the landmark, P. mellyi typically extends and contracts its gaster (posterior abdominal region) to display the three white stripes on its tergites. Seven main patrolling behaviors for when the males are in flight have been identified: #Detour flight: short flights (for 5–30 seconds) around the hover landmark #Solitary display: white dorsal stripes displayed (for 5-40s) in the absence of male competitors #Display inducement: another wasp displays its white stripes while flying behind the male #Elicited display: white stripes displayed in front of more than one pursuer #Zigzag display: distended abdomen hovering horizontally for a few seconds #Attack: leg of wasp touches the back of the patrolling male, and the abdomens of the wasps sometime come into contact when the pursuer turns around and flies backwards #Received attack: hover male is attacked and hit by the legs or body of the pursuer Patrolling flights usually take place at certain, well-defined hours of the day. In the West Java region, it has been recorded that P. mellyi leave their nests around 11:00am and return around 12:45pm.
Some jumping spiders of the genus Portia hunt other spiders in ways that seem intelligent, outflanking their victims or luring them from their webs. Laboratory studies show that Portias instinctive tactics are only starting points for a trial-and-error approach from which these spiders learn very quickly how to overcome new prey species. However, they seem to be relatively slow "thinkers", which is not surprising, as their brains are vastly smaller than those of mammalian predators. ant- mimicking jumping spider Ant-mimicking spiders face several challenges: they generally develop slimmer abdomens and false "waists" in the cephalothorax to mimic the three distinct regions (tagmata) of an ant's body; they wave the first pair of legs in front of their heads to mimic antennae, which spiders lack, and to conceal the fact that they have eight legs rather than six; they develop large color patches round one pair of eyes to disguise the fact that they generally have eight simple eyes, while ants have two compound eyes; they cover their bodies with reflective bristles to resemble the shiny bodies of ants.
