The female of this wasp lays an egg inside the first instar larva of the sunflower stem weevil, and when that larva enters diapause in the fall, in a chamber near the base of the plant, the wasp larva also goes into hibernation. Both larvae resume activity in the spring, and about twenty days later, the wasp larva exits the weevil larva, feeds on its carcase and pupates. The adult wasp emerges about ten days later, both insects having a single generation each year.
At 48 hours, the trochophore larva becomes a metatrochophore larva. Both trochophore and metatrochophore swim with a ring of cilia in the water and are positively phototactic.

When not eating, the larva will remain on the underside of the leaf and make a mat of silk for attachment. Gypsy moth caterpillar in frontal view To grow, the larva must molt. Larva are characterized by the term instar, which refers to the number of times a larva has molted; a first-instar larva has not yet molted, a second instar has molted once, a third instar twice, etc. Males typically are five instars and females are six instars.
The larva completes five instars before pupating, developing over a period of around 10 to 12 weeks. The first instar larva has a black body with many hairs, and a dull black head. As the larva feeds on its host plant S. lanceolatum, it sequesters in its body sarmentosin from the plant, causing the larva to become distasteful to predators. Conspicuous yellow markings appear on the body after the second instar, warning off predators, as the larva stores higher levels of sarmentosin.
The adult soldier beetles will eat the aphids, caterpillars, grasshopper eggs and mites. The larva of the soldier beetle hatches in the spring. The larva soldier beetles prey upon insect eggs, larva, snails, and slugs. The soldier beetle lays its eggs in the late summer.

It lays an egg in the nest cell of the cicada killer, and when the cicada killer larva pupates, the parasitoid larva consumes the pupa.
However, if the larva is ever removed the spider returns to normal control and behaviors. The longer that a larva is able to remain on a spider, the longer it will take that spider to recover if the larva is taken off. This action also supports the hypothesis that the change in behavior is most likely the result of an accumulation of hormones stimulated or released by the larva. Before the spider is fully able to reach adulthood, the larva enters the pupal stage.

Generally, the 1st-instar larva crawled into the heart leaf or the leaf sheath nearby, and the 2nd-instar larva began to spin silk at the leaf tip, and then began to turn into a small insect bud after the 3rd-instar. The food intake at 4th and 5th instar, which accounting for more than 90% of the total food intake of the larva.
Larva of Papilio xuthus, butterfly A larva (plural larva ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larva phase of their life cycle. The larva's appearance is generally very different from the adult form (e.g. caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form.
The milky secretions of this gland are expelled out of the gland duct at the head end of the larva. The larva sucks up the milky secretion and passes it directly to the midgut where it is slowly digested and assimilated. For air supply, the larva depends on air entering the vulva of the female. The air must pass into the female's posterior spiracles or polypneustic lobes to reach the larva.
First-instar larva are initially translucent white, becoming opaque white. The second instar integument is black and the third instar has jet-black setae. The verrucae of the fourth instar are more pronounced than in previous instar. When mature, female larva are about twice as large as male larva.

Ocular larva migrans (OLM), also known as ocular toxocariasis, is the ocular form of the larva migrans syndrome that occurs when Toxocara canis (dog roundworm) larvae invade the eye. They may be associated with visceral larva migrans. Unilateral visual disturbances, strabismus, and eye pain are the most common presenting symptoms.
The resulting zygote develops into a ciliated larva that escapes from the mother to seek out new hosts. Once it finds a host, the larva loses its cilia and develops into a syncytial plasmodium larva. This, in turn, breaks up into numerous individual cells that become the next generation of adults.
After hatching the larva of the parasitoid attacks the bee larva when it has spun its tough cocoon. When mature the C. hirsuta larva spins its own cocoon inside the bee larva's cocoon. C. hirsuta seems to have an obligate, minimum, two-year life cycle which parallels that of O. inermis.

Third instar larva of olive fruit fly The egg is around 0.7 to 1.2 mm long, elongated, and slightly flattened in its stomach, with a small, white microfleece nodule, which is important for the respiration of the embryo. The larva is Caecilian and has a conical-cylindrical, narrow front. It develops through three stages (larva, first, second and third stage). The mature larva is 6–7 mm long, white-yellowish in colour, elongated, and subconical.
A special variant is ocular larva migrans where usually T. canis larvae travel to the eye. Only a few roundworm eggs are necessary to cause larva migrans in the human child or adult. However, visceral larva migrans seems to affect children aged 1–4 more often while ocular larva migrans more frequently affects children aged 7–8. Between 4.6% and 23% of U.S. children have been infected with the dog roundworm egg.
M. paradoxus is primarily a parasitoid of the common wasp Vespula vulgaris. Adult females lay eggs in decaying wood in autumn, which hatch in spring or summer. The first instar triungulin clings to a V. vulgaris worker to be transported to the nest. Once at the nest, the larva parasitises a wasp larva - once the larva has closed the cell, the M. paradoxus larva consumes the host and pupates in its place.
The larvae feed on various plants, including Salix, Alnus and Betula species.Pacific Northwest Moths The species first overwinters as a fifth-instar larva and again as an eighth instar larva.
This larval stage lasts less than four days, before the young moult into the post-larval stage. The post-larva swims using its pleopods. The post- larva later moults into the adult form. Larvae are rarely seen in the wild, confirming that the development to the bottom-dwelling post-larva is rapid.
The species is named for the curious resemblance of the larva to a young larva of one of the Sphingidae, the protruding tubercle above the head having exactly the appearance of an anal horn, while the attenuation of the body posteriorly represents the form of a Sphingid larva in the reverse position.
Anopheles larva from southern Germany, about 8 mm long Feeding position of an Anopheles larva (A), compared to that of a nonanopheline mosquito (B) The mosquito larva has a well-developed head with mouth brushes used for feeding, a large thorax and a nine-segment abdomen. It has no legs. In contrast to other mosquitoes, the Anopheles larva lacks a respiratory siphon, so it positions itself so that its body is parallel to the surface of the water. In contrast, the feeding larva of a nonanopheline mosquito species attaches itself to the water surface with its posterior siphon, with its body pointing downwards.
As with most mantidflies, this species is parasitic to spiders as larva: the eggs of wolf spiders are their preferred host and larva will get themselves wrapped up with the eggs in the sac by the spider, since they cannot break into the sacs themselves. If the spider hasn't yet laid eggs, the larva will subsist on the spider's blood until then. Once inside the sac the larva will feast on the eggs until it pupates.
In the first stage, the pale grey body of the larva has longitudinal brown lines, a number of black-knobbed hair like structures, a brown head with no horns, and a rear with no fork. In the following stages, the rear develops a fork, the longitudinal lines become green, and the larva itself becomes green. The mature larva is green and about 28 mm long. The feeding habits for the larva extend from winter through early spring.
O. furnacalis larva with damage done to corn ear shown The Asian corn borer goes through six instar stages while in the larval phase. The first-instar larva is pinkish with dark spots and a dark head. The late instar larva is yellow brown with dark spots and reaches up to 2.9 centimeters in length.
Temperatures above 32 °C increase growth and development. Rainfall can drown larva before they are established, low populations are correlated to heavy rainfall during the larval stage. Wind is also critical to the dispersal of the larva, wind speeds of several miles per hour are enough to break the silk threads and disperse the larva.
After the last instar larva finds a location to begin diapause, it will spin a cocoon for itself. In laboratory experiments, the larva will wander several centimeters above the food layer before finding a satisfactory location to pupate. Once the last instar larva begins to diapause, it will spin itself a thin silk cocoon.
The anterior parts of the body of the larva are more heavily sclerotized and pigmented. The thoracic legs are quite long, and the larva bears great resemblance to the larvae of Trichoptera.

A tornaria larva A tornaria is the planktonic larva of some species of Hemichordata such as the acorn worms. It is very similar in appearance to the bipinnaria larvae of starfishes, with convoluted bands of cilia running around the body. It is an oval shaped, transparent larva. The diameter of the body is about 3 mm.
These spend several weeks in the water column, feeding on plankton. Over a series of moults, the larva passes through six naupliar instars before changing into a cypris larva, with a two-valved carapace. These larvae can survive weeks embedded in sea ice. The cypris larva does not feed but seeks out a suitable substrate for its adult life.
Larva Pupa The larvae feed on Atriplex halimus. They mine the leaves of their host plant. A single larva mines a number of the central leaves. Older larvae live freely amongst spun leaves.

The eggs hatch after four weeks and each preparasitic larva searches for a suitable host; it will die if it does not find one within seventy-two hours. It bores a hole through the cuticle of the host mosquito larva with a stylet, and develops in its body cavity. When ready to leave the mosquito larva, it bores a larger hole through which it emerges. The mosquito larva does not survive because its body fluids leak out through the hole.
One of the most effective controls is used during the larva stage. Beetle larva can be controlled using milky spore disease (Bacillus popilliae), which occurs naturally in some larva. Milky spore treatment was first developed by the USDA in the 1930s to combat the Japanese beetle but milky spore controls the June bug and Oriental beetle as well. Milky spore treatment was the first microbial product ever registered in the US. Milky spore begins working after treatment wherever larva are feeding.
In all other species, the egg develops into a free-swimming larva, typically after around three days of development. The first stage of larval development is known as an auricularia, and is only around in length. This larva swims by means of a long band of cilia wrapped around its body, and somewhat resembles the bipinnaria larva of starfish. As the larva grows it transforms into the doliolaria, with a barrel- shaped body and three to five separate rings of cilia.
The larva passes through a further five naupliar stages by ecdysis, with increasing numbers of setae (bristles) appearing on the appendages at each stage. Around 41 hours after hatching, the larva moults into the first protozoea stage, by which time the body is long. The body is now differentiated into a cephalothorax and an abdomen, bears several thoracic appendages, and the larva now begins to ingest food. After a further two protozoea stages, the larva hatches into the first mysis stage.
The G. fuscipes larva in passes through three instars as it grows up to when the fully grown larva is dropped by a female fly. The larva has a mouth at the anterior end and two spiracles at the posterior end. Rather unusually, the larva spends most of its time and does all its feeding within the mother's body. Apart from food stored in the egg, the food supply for the three larval instar stages comes from the mother's milk gland.
The larva has a blind gut and the body consists of a head and its three pairs of cephalic appendages only: the chelifores, palps and s. The abdomen and the thorax with its thoracic appendages develop later. One theory is that this reflects how a common ancestor of all arthropods evolved; starting its life as a small animal with a pair of appendages used for feeding and two pairs used for locomotion, while new segments and segmental appendages were gradually added as it was growing. At least four types of larvae have been described: the typical protonymphon larva, the encysted larva, the atypical protonymphon larva, and the attaching larva.
In most species, this larva has 12 elongated arms lined with bands of cilia that capture food particles and transport them to the mouth. In a few species, the blastula contains supplies of nutrient yolk and lacks arms, since it has no need to feed. Several months are needed for the larva to complete its development, the change into the adult form beginning with the formation of test plates in a juvenile rudiment which develops on the left side of the larva, its axis being perpendicular to that of the larva. Soon, the larva sinks to the bottom and metamorphoses into a juvenile urchin in as little as one hour.
The larva is also very variable, being green to reddish brown with alternating darker and lighter stripes. It feeds on various species of St John's wort (Hypericum species). It overwinters as a small larva.
Cutaneous larva migrans is a condition where nematodes such as Ancylostoma braziliense migrate to the skin. A list of causative agents of larva migrans syndromes is not agreed upon and varies with the author.
Eventually the larva completely devours the ant's brain, which often falls off (hence the species nickname: "decapitating fly"). The larva then pupates in the empty head capsule, emerging as an adult fly after two weeks.
The larva has been recorded on Hiptage benghalensis and Combretum latifolium.

They made no effort to pounce on the spiders, but when one climbed on the back of the larva, it arched its tail and head, trapping the spider between the tail spine and the mandibles. The larva then devoured the spider, at the same time relaxing its tail. In another study, several spiders were released in the presence of a single larva and they were all later found congregated on its back. The researchers thought it possible that the larva released an allomone which attracted the spiders.
The Metroid larva is chronologically the last Metroid of its race following the events of Metroid II: Return of Samus and Metroid: Samus Returns. Samus describes how a Metroid larva hatched from an egg and immediately imprinted upon her, believing her to be its mother. She brought the larva to Ceres Space Colony, where scientists learned that they could harness its power. Just after she left the colony, she received a distress call and returned to find the scientists dead and the larva stolen.
The lighter infection in OLM is believed to stimulate a lower immune response and allow for migration of a larva into the eye. Larvae are thought to enter the eye through the optic nerve, central retinal artery, short posterior ciliary arteries, soft tissues, or cerebrospinal fluid. Ocular granulomas that form around a larva typically are peripheral in the retina or optic disc. Visceral larva migrans seems to affect children aged 1–4 more often while ocular larva migrans more frequently affects children aged 7–8.
The larvae of Lomechusa pubicollis live inside colonies of the European red wood ant Formica polyctena, or the red wood ant Formica rufa. Each larva produces a glandular secretion which persuades worker ants to groom it. The beetle larva rears up in a manner that imitates the begging behaviour of an ant larva, touching the worker ant on its mouthparts, which stimulates it to regurgitate a drop of liquid food. The beetle larva also feeds on ant larvae as well as smaller larvae of its own species.
The larva vacates the mine by an opening in the lower epidermis and lives freely in a leaf margin that has been folded downwards. Within this fold, the larva starts feeding in the apical section, working downwards. The frass is deposited in the oldest part of the fold. During feeding pauses, the larva rests still untouched central part of the fold.
The female fly will produce a single larva at a time, retaining the larva internally until it is ready to pupate. The larva feeds on the secretions of a milk gland in the uterus of the female. After three larval instars, a white pre-pupa which immediately forms a hard dark puparium. The pupa is usually deposited where the deer slept overnight.
The female fly will produce a single larva at a time, retaining the larva internally until it is ready to pupate. The larva feeds on the secretions of a milk gland in the uterus of the female. After three larval instars, a white pre-pupa which immediately forms a hard dark puparium. The pupa is usually deposited where the deer slept overnight.
The larva constructs a silk-lined gallery, which serves as a shelter when the larva is not feeding. The frass is partly inside the mine, but most of it is rejected through a hole at the beginning of the mine. The black pellets of frass on the underside of a leaf indicate the presence of a larva. New mines are made very often.
The fully grown larva is 0.75 to 1 inch (1.9-2.5 cm) in length. Larva vary in color from light brown to pinkish gray and have conspicuous small, round, brown spots on each segment along the body. As they grow they reach between 2 and 20 mm. The larva feed on the corn whorl and burrow into the stalk and ear.
The first-instar larva usually feeds on the pistil, then on the stamens. It remains in the bud in which the egg was laid throughout the first instar. The second-instar larva also usually remains in the initial bud but it may bore into an adjacent bud. Subsequently, as the larva develops, it bores into other florets, eating the inner parts of them.
The egg is about across, and hatches into a larva that superficially resembles a trilobite. Indeed, it is often referred to as the 'trilobite larva'. Through a series of successive moults, the larva develops additional gills, increases the length of its caudal spine, and gradually assumes the adult form. Modern xiphosurans reach sexual maturity after about three years of growth.
Larva Adults measure approximately 4 cm (1.5 inches), are black with six relatively large, white, dorsal spots (four over the elytra and two on the thorax). Other patterns are possible although the pattern is always symmetrical. The larva has a flattened form, a large head capsule, and prominent mandibles.Gardner, J. C. M. (1939) The Larva Of Anthia Sexguttata(Fab.) (Coleopt. Carabidae).

There Brian collected a remarkable psychodid larva occurring in the torrential streams.
A larva develops in the egg and hatches through the operculum; the swimming larva is ciliated and called an oncomiracidium. The larva finds its host by swimming to it, first attaches to the skin and migrates to the gills, and eventually transforms itself into a young monogenean which is attached to the gill filament by its haptor. During transformation from larva to adult, the monogenean loses its cilia and produces a new tegument, a phenomenon which is considered a general characteristic of the parasitic Platyhelminthes or Neodermata.Ehlers, U. (1985).
Mushroom-feeding Drosophila are also frequently parasitized by parasitoid wasps such as Leptopilina sp.. These wasps infest the fly larva by inserting their ovipositor into the larva and depositing an egg internally. The wasp larvae hatch within the host, and remain relatively benign until fly pupation. This is because the wasp larva requires the fly larva to develop to the point of pupation so the wasp itself can metamorphose within the puparium in place of the fly. This process ultimately kills the fly, which is devoured by the developing wasp.
They are protandrous hermaphrodites, except for Oikopleura dioica which is gonochoric, and a larva resembles the tadpole larva of ascidians. Once the trunk is fully developed, the larva undergoes "tail shift", in which the tail moves from a rearward position to a ventral orientation and twists through 90° relative to the trunk. The larva consists of a small, fixed number of cells, and grows by enlargement of these rather than cell division. Development is very rapid and only takes seven hours for a zygote to develop into a house-building juvenile starting to feed.
Female larva much pale green. Larva known to feed on Cassia auriculata, Acacia, Albizia, Camellia sinensis, Chrysanthemum indicum, Dalbergia latifolia, Eucalyptus, Litchi chinensis, Mangifera indica, Paulownia tomentosa, Phyllanthus emblica, Prunus domestica, Prunus salicina, Psidium guajava, and Vernicia fordii'.
Going underground during the pupa and adult stages allows them to survive the winter. Larva and adults will often have overlapping niches, with the larva developing on the ears of the corn and eventually feeding on the kernels.
There is a distinctive dark blotch behind upper part of gill opening, which can easily identify the species from other Thryssa species. Caudal fin is yellowish. It feeds on planktons, fish larva, and small crustaceans like shrimp larva.
Population density of larva plays a major role in their behavior. At low density, larva remain inactive during the day, but in high populations become hyperactive. Interbreeding produces deleterious genetic effects, and dispersal serves to reduces this effect.
The butterflies emerge between August (later at higher altitude sites) and November, with a two-week peak of activity in September. After mating, the female oviposits eggs on or near the area of Bursaria spinosa subsp. lasiophylla. After hatching, the larva is attended by the ant A. itinerans which is thought to offer the larva predator protection and receive nutritional secretions from the larva.
Some of the most important zoonoses are parasitic. Zoonotic intestinal parasites transmitted through contact with feces include Toxocara canis (the canine roundworm), which causes toxocariasis, visceral larva migrans, and ocular larva migrans, and hookworms, which can cause cutaneous larva migrans. Zoonotic skin parasites include scabies, caused by the mite Sarcoptes scabiei. The most common zoonotic fungal disease is ringworm, caused in this case by Microsporum canis.
June bug larva stage The grubs will grow to about and are white with a brownish-black head and brown spiracles along the sides of the body. The larvae will molt twice before winter. The fully grown larva color is glassy yellowish white shading toward green or blue at the head and tail. The larva has stiff ambulatory bristles on its abdomen which assist movement.
The developed larva within the egg does not emerge until the prolonged autumn showers wet the eggs. Once the larva wants to emerge from the egg, it partially cuts open a part of the shell and pushes its way out. In most cases the larva eats the shell to immediately nourish its weak body. It then finds its way to young grass areas to further nourish itself.
Instead, a segmented shell gland forms on one side of the larva, and a foot forms on the opposite side. When the larva is ready to become an adult, the body elongates, and the shell gland secretes the plates of the shell. Unlike the fully grown adult, the larva has a pair of simple eyes, although these may remain for some time in the immature adult.
Sheep keds live for typically four to six months, and may produce from 10 to 20 larvae. The female fly produces a single larva at a time, retaining the larva internally until it is ready to pupate. The larva feeds on the secretions of a "milk" gland in the uterus of the female. After three larval instars, the white prepupa immediately forms a hard, dark puparium.
Adult and larvae stage of Pericoptus truncatus An exotic Scoliidae wasp, the yellow flower wasp, Radumeris tasmaniensis has been found in Northland, North Island, New Zealand. This has been a cause for concern as R. tasmaniensis parasitises on the large sand scarab's larvae. The female stings and paralyses the scarab larva and lays eggs on it. The wasp larva then slowly consumes the paralysed beetle larva.
The male has a wingspan of 10–30 mm. The larva is green with yellow lines. larva Adults emerge from overwintering pupae in February and March. The females climb up tree trunks and the males fly weakly to them.

A journal article by George Wheeler observed the larvae of the species. Lengths for very young larva is 3.7 mm, young larva 5.4-10.2 mm, immature larvae around 8.7-10.3 mm and mature larvae grow to lengths of 8.3-15.4 mm.
This idea, proposed by Otto Bütschli, suggests that metazoa are derived from a planula; that is, the larva of certain cnidaria. Under this hypothesis, the larva became sexually mature through paedomorphosis, so could reproduce without passing through a sessile phase.
Medetomidine can be used as an antifouling substance in marine paint. It is mainly effective against barnacles, but has also shown effect on other hard fouling like tube worms. When the barnacle cyprid larva encounters a surface containing medetomidine the molecule interacts with the octopamine receptor in the larva. This causes the settling larva to increase its kicking to more than 100 kicks per minute, which makes becoming sessile nearly impossible.
The egg hatches into a white, legless larva. The larva will feed on the soft fibres and terminal buds, tunneling through the internal tissue of the tree for about a month. The larvae can occasionally grow to a length of six to seven centimeters. At pupation, the larva will leave the tree and form a cocoon built of dry palm fibers in leaf litter at the base of the tree.
The female lays eggs inside the leaf tissues of a susceptible plant, creating small puncture holes. The developing larva feeds on the leaf tissue, creating a tunnel between the upper and lower surfaces as it advances. This starts small but gets wider as the larva increases in size. After three instars, the larva cuts a slit, usually in the upper leaf surface, and falls to the ground where it pupates.
When feeding on Ligularia tussilaginea, the larva usually eats the leaf from the upper surface and the lower epidermis is left untouched. Rarely, the larva eats the leaf from the under surface. The pupa is usually attached to the upper surface of a leaf. When feeding on Ligularia fisheri, the larva eats the leaf from the upper or under surface and eats large patches, here the epidermis is not left.
Nauplius larva of Elminius modestus Nauplius larva of a barnacle with fronto- lateral horns A fertilised egg hatches into a nauplius: a one-eyed larva comprising a head and a telson, without a thorax or abdomen. This undergoes six moults, passing through five instars, before transforming into the cyprid stage. Nauplii are typically initially brooded by the parent, and released after the first moult as larvae that swim freely using setae.
The larvae are aquatic, but there must be enough solid food for the larva to complete development. This is why they are found in water with high levels of organic matter. The siphon on the back of the larvae remains at the surface of the water while the larva moves throughout the water. This allows for the larva to search for food without having to go to the surface to breathe.

In all the remaining orders of the Endopterygota the larva is eruciform or vermiform.
Neosabellaria cementarium has trochophore larvae which form part of the plankton. Each larva has a ciliated band with two bundles of long, barbed setae (bristles), one on each side of its body. These are fanned out when the larva is feeding and seem to have a defensive function, perhaps preventing a predator from recognizing the larva as a prey item or irritating the mouth tissues of comb jellies or other predators. Another band of short cilia at the posterior end of the larva enable it to swim, and when it is doing this, the setae are held alongside the body.
The larva is grey with a purplish- brown back. It has been recorded feeding on bedstraw, Corydalis, globeflower, hemlock and primrose and probably feeds on other low-growing plants. The species overwinters as a larva. #The flight season refers to the British Isles.

These branches each contain a brood cell, and once each cell has pollen and nectar for the larva to feed on - a small doorway to the brood cell is closed. The larva grows rapidly, but the bees do not emerge until spring.
There is probably one generation per year. The larvae feed on Coronilla juncea. The larva makes a very conspicuous gallery mine in the green bark, in which the living larva can easily been seen. The mine often starts contorting, frequently encircling the stem.
The larva mines in the lower leaves. After the case has been tightened to the leaf, the larva leaves the case and makes a long corridor mine. Larvae can be found from September to May. After hibernation, the larvae do not feed.
Artemia spp. can reproduce both sexually and asexually. The life cycle of F. liguloides begins by Artemia ingesting the cestode larva, called oncosphere. It then penetrates the intestinal wall into the hemocoel where it becomes a cysticercoid, or larva with a scolex.

Induced spawning by hormone-operation, egg-development and larva of blind gobioid fish, Odontamblyopus rubicundus.
Cool springs have a higher dissolved oxygen concentration than warmer springs. Glossosomatid larvae do not normally have gills, meaning that they respire through their cuticle. A higher dissolved oxygen concentration on the outside of the larvae allow more oxygen to be utilized by the larva. Fast flowing streams, on the other hand, allow more water to pass over the cuticle of the larva, again resulting in the larva utilizing more dissolved oxygen.
The moth lays the egg on the young capsule. The hatched larva gnaws into the fruit, which closes the minute hole during its growth. The larva attaches itself to the capsule with many silken threads by hooks on its anal and four hind abdominal prolegs. When the fruit is warmed, for instance by being held in the palm of the hand, the larva twitches, pulling on the threads and causing the characteristic hop.
The fly larva mines the leaves and stems of the fern's frond at the apex. The tip of the frond rolls upwards into a loose, obvious knot or mop-head structure involving many pinnae; inside, a white larva mines along the rachis, eating the trichomes, causing it to coil. Usually, only one larva is present in the leaf tip, sometimes two. An elongated white egg shell is visible at the centre of the mass.
The affinities of Balanoglossus with echinoderms were first suggested by Metschinkoff (1865). There are no similarities between adults of echinoderms and Balanoglossus except in the presence of intraepidermal nervous system. However, the striking resemblance between the larval forms of the two groups misled Muller to regard tornaria larva as a larva of starfish. The similarities between tornaria larva and bipinnaria and other larval forms of echinoderms are as follows: 1) They are pelagic and transparent.
Sometimes the larvae are killed by the pathogenic fungus Zoophthora phytonomi, especially in warm and humid weather. They may also be parasitized by ichneumon wasps, Bathylplectes anurus and B. curculionis. The female of these wasps is only about long, and lays an egg inside an early stage of the larva of the weevil. The developing wasp larva is a parasitoid, living inside the weevil larva and devouring it, eventually pupating soon after its host.
The newly emerged larva is up to about 0.7 millimeters in length, not counting the two long, thin caudal setae, which are twice the length of the body. The new larva is cream-colored with a light brown, well- developed head. By the second and third instars, there are four caudal setae. The fourth instar larva is around 5 millimeters long including the caudal setae, which are about as long as the body.
When morphine levels are high in the fly's food source there are more secretions from the larva. Methamphetamine, on the other hand, does affect the C. stygia larval development. Larva that had been raised on meth-infused meat developed faster and ended up larger in size, and weight. The increase in body size poses a problem for determining relative ages of larva since most use body size as an indication of age.
Lion's mane jellyfish have four different stages in their year-long lifespan: a larval stage, a polyp stage, an ephyrae stage, and the medusa stage. The female jellyfish carries its fertilized eggs in its tentacle, where the eggs grow into larva. When the larva are old enough, the female deposits them on a hard surface, where the larva soon grow into polyps. The polyps begin to reproduce asexually, creating stacks of small creatures called ephyrae.
When the larva moves out of the abdomen, it remains connected to the hemolymph for nutrients as an ectoparasitoid. How large the larva gets ultimately depends on the size and nutrient availability of the spider. The spider may continue to forage and take part in activities that ultimately increase the fitness of the larva. However, Z. percontatoria has to be careful because it have to protect itself and the spider from their predators.
The larva of the fish louse has two main stages. In its newly hatched stage it has been termed a "metanauplius", like the nauplius of many other crustaceans, but with a swimming apparatus that is more developed. It may even be too well developed for the larva to be called a nauplius at all. The newly hatched larva can parasitize a host, attaching to it with its hooked antennae because it lacks suction cups.
Chilodonella uncinata has a cosmopolitan distribution. It is suspected to act as a facultative endoparasite of the larvae of the Culex, Aedes, and Anopheles mosquito larva. It lives in fresh water ponds, lakes, creeks, and bayous where it feeds on bacteria and other microbes. Microscopic examination of cytological samples showed that mosquito larva containing subcutaneous encysted C. uncinata had a 25-100% mortality in the mosquito larva, but no viability examinations were conducted.
The female fly lays an egg in the bud of Salix repens. The solitary, orange larva feeds within the bud which grows into a 13 mm long, horn-like, reddish tube which tapers to the tip. Development of the larva probably takes two years.
The larva is oval shaped with a flattened underside. Some species have honeydew glands that attract ants. Ants like to eat and collect the honeydew made by the caterpillar. In turn, the ants will swarm over anything that might try to harm the larva.

The larva is described as purplish with a pale green vascular line and a row of reddish-brown dorsal dashes. However, the purple colour of the larva is not conclusive, as the colour is often produced in larvae which feed on leaves with autumnal colouration.
It initially bores in the petiole, causing a gall-like swelling. After the last moult, the larva enters the leaf and creates a blotch. The larva mainly feeds and night, and retreats into the petiole at daytime. Pupation takes place outside of the mine.
B. major adult Larvae live parasitically in the nests of various solitary bees and wasps. When the fly larva locates a host larva, it will consume it slowly, greatly increasing in size as it tightly holds onto the host, eventually becoming a pupa and overwintering.
Alysiinae are koinobiont endoparasitoids of cyclorrhaphus Diptera. Females oviposit into host eggs or larvae. The host is allowed to develop until it forms a puparium, at which point it is killed by the wasp larva. The Alysiinae larva then pupates within the host puparium.

In each of these existences the larva or mask is the prefigurement of the succeeding existence.
After a filariform "infective" larva penetrates the intact skin – most commonly through the feet – the larva enters the blood circulation. It is then carried to the lungs, breaks into alveoli, ascends the bronchi and trachea, and is coughed up and swallowed back into the small intestine, where it matures. The larva later matures into an adult in the small intestine (jejunum mainly), where they attach to the villi and female worms can lay 25,000 eggs per day. The eggs are released into the feces and reside on soil; when deposited on warm, moist soil, a larva rapidly develops in the egg and hatches after 1 to 2 days.

Picture of the embryo of a Larch Casebearer protruding from its case Larva are 5–6 mm long, hatch in July, and pupate about 11 months later. The first and second instar larva hatch and bore directly from the egg into the needle, and mine inside the needle until August or September, during which the hollowed out needle is converted into the distinctive case. Once the case is created, the larva progress to the third instar during which the case is fastened to a new needle with silk. The larva continue to mine the needles discarding old cases as new needles are hollowed out and converted.
The larva of Cicindela dorsalis, the eastern beach tiger beetle, is notable for its ability to leap into the air, loop its body into a rotating wheel and roll along the sand at a high speed using wind to propel itself. If the wind is strong enough, the larva can cover up to in this manner. This remarkable ability may have evolved to help the larva escape predators such as the thynnid wasp Methocha. Members of the largest subfamily of cuckoo wasps, Chrysidinae, are generally kleptoparasites, laying their eggs in host nests, where their larvae consume the host egg or larva while it is still young.
The larva are considered pests because they damage the plant tissue under the soil. The larvae are cannibalistic. AdultThe larva can range in color from light gray or gray brown to black. The ventral side is usually lighter, and this species does not have a dorsal band.

This moth flies at night in June and July in the British Isles. It is attracted to light. The larva feeds on the leaves and soft bark of a wide range of trees and other plants (see list below). The species overwinters as a small larva.
These functions serve not only to protect the larva from other bacteria, but they also digest complex molecules which allow the larva to easily absorb nutrients without expending a lot of energy. The bacteria, in turn, receive a supply of food which results in a mutualistic relationship.
In the early stages the larva is black over the thorax narrow above the prolegs, and broadening again at the tail end. The larva is smooth. The sides above the prolegs are yellow ochre. A narrow border around the head and the anal segment yellow ochre.
There are three main syndromes: visceral larva migrans (VLM), which encompasses diseases associated with major organs; covert toxocariasis, which is a milder version of VLM; and ocular larva migrans (OLM), in which pathological effects on the host are restricted to the eye and the optic nerve.
Coleophora millefolii is a moth of the family Coleophoridae. It is found in most of Europe, except Great Britain, Ireland and the Iberian Peninsula. Sprig of Achillea millefolium with larva-case attached Larva The wingspan is . Adults are on wing from the end of June to August.
The larval period coincides with the feeding period, which typically lasts between 20 and 21 days. Following the feeding period, the larva then enters a wandering period during which the larva will move out of the food. The larvae period will last between 2 and 6 days.
The larva feeds on a variety of plants such as bedstraw, oak and willow, as well as various grasses. The species overwinters as a larva, remaining active and feeding throughout. #The flight season refers to the British Isles. This may vary in other parts of the range.
The larva feeds on the host and molts to a nymph. The nymph is similar to the larva but has four pairs of legs. Then the nymph feeds and molts. This molt is either to the first of several more nymph stages, or to an adult.
One study of the species Stelis ater found they differed a bit from other thieving bees by being hospicidal (host-killing) at all larval stages, and neither it nor its host larva move much, so it is simply a matter of chance when its growth brings it into contact with the host rather than with just the provisions. This is in contrast to other kleptoparasitic bees which usually have their more mobile first instar larva kill the host larva.
The larva hatches inside of the host and grows and develops until it takes up the majority of the host's abdomen. The host then dies and the larva envelopes itself in a puparium and pupates inside of the corpse. After an extended period of pupation, the adult emerges from the corpse of the host bee. When a bee becomes parasitized by a P. tibialis larva, certain behaviors such as induced grave digging and changes in flower preference often occur.
The life cycles of Schistosoma japonicum and Schistosoma mansoni are very similar. In brief, eggs of the parasite are released in the feces and if they come in contact with water they hatch into free-swimming larva, called miracidia. The larva then has to infect a snail of the genus Oncomelania such as species of Oncomelania hupensis within one or two days. Inside the snail, the larva undergo asexual reproduction through a series of stages called sporocysts.
This will aid the fitness of the larva when it enters the pupal stage by creating a camouflage, and protecting it from predators and the outside conditions of the environment. When the web is done, the larva kills the spider host and consumes its body. The larva is then ready to enter the cocoon where a metamorphosis takes place. The pupa will emerge as an adult wasp, usually female as they are able to reproduce starting the cycle again.
The female may produce up to 285 eggs which are laid within a food source. The larva are yellowish-white with a brown head and can reach a length of up to 3mm, larva are active and move about through a food source as they feed. Larva molt two to four times before pupating in a cocoon-like structure made by joining together small grain kernels and pieces of kernels. The total life cycle takes approximately 27–50 days.
They are predators of terrestrial snails. Upon reaching maximum size (about 20 mm) the larva seeks out a snail shell in which to pupate. By clinging to a snail's shell via the suction cup on the terminal segment of the abdomen, the larva then bites the snail, injecting paralyzing venom that liquefies the snail's flesh with digestive enzymes. The flesh of the snail is then soft enough for the larva to burrow through the snail and enter the shell.
One egg is deposited in each cockroach egg capsule, and the wasp larva consumes all the eggs within it. The larva proceeds through five instars during development, stages which are distinguished by the changes in the unique mandibles. The first instar has mandibles with small, sharp teeth which it must use to open the tough cockroach eggs. During the next two instars, the larva has longer mandibles which are "shaped like a gauntlet glove" with three teeth.

Most of the day, males perch on grass blades or stems to await females. Females lay their greenish white eggs on or near the host plant. The larva lives in a nest by tying leaves together with silk. The variable brown larva is indistinguishable from closely related larvae.
The fully grown larva is about 9–10 mm long and found inside a movable case. After mating, females lay eggs within its case. Each female can produce about 110 to 200 eggs. Soon after hatching, a larva starts to make a case using leaves of the host plant.
Neofaculta ericetella is a moth of the family Gelechiidae. It is found in Europe and Asia Minor. A sprig of Erica with a larva protruding from a flower Larva The wingspan is 13–18 mm. The moths are on wing from April to July depending on the location.
A maturing larva induces a painful swelling. In approximately 12 to 15 days, the larva reaches a length of about 23 mm, exits the skin of the host, and falls to the ground to pupate. The adult fly emerges in 23 to 26 days, and the life cycle continues.
The eggs are cylindrical with rounded ends, white, opaque and shiny, and about long. The larva is a white, legless grub, with a brown head and brown tip to the abdomen. As it grows, lateral rows of pale brown tubercles become apparent. The fully grown larva is long.
Larva severely devastate the shoot tips. The point it emerges is completely eaten first through and few internodes below the growing point are packed with frass, results so called "dead heart". Feeding on shoot bases by more developed larva is indistinct. Leaves may yellow and wilt from shoot base.
There is a complex interaction between JH, the hormone ecdysone and vitellogenin. In the development stage, as long as there is enough JH, the ecdysone promotes larva-to-larva molts. With lower amounts of JH, ecdysone promotes pupation. Complete absence of JH results in formation of the adult.
Females lay their eggs singly on the underside of host plant leaves a few inches above the bog surface. The whitish egg can withstand flooding. The larva is bluish-green with a darker green middorsal stripe. The bog copper larva is the only copper that feeds on cranberries.
No type material was preserved. Because the larva is described as having ten square-dark-brown or blackish spots, this suggests that the species belongs to Ectoedemia. The black spots are lost by the time the final stage larva is reached. Therefore, the described mines also possibly also incomplete.
P. tibialis remains enclosed in its Hymenopteran host for the entire larval stage of development. During the first and second instar stages, the larva primarily consumes the hemolymph of the host for nutrients. During the third instar stage, the larva begins to consume the intestinal tissue of the host.
In this case they overwinter. After hibernation, the larva makes a new case in the same manner. It hibernates for the second time and constructs yet another case. The case of the full-grown larva is a spatulate leaf case of , composed of two elongates pieces of epidermis.
Each molt of the larva results in loss of infection, but it is generally quickly re-acquired from the environment by ingestion of more amastigotes. When the fourth instar larva pupates the amastigote infection is maintained in the gut through metamorphosis giving rise to an infected adult mosquito.
The larva is brown or greyish ochreous, sometimes tannish peach; the lines pale with darker edges. It feeds on various grasses including Alopecurus, Dactylis, Deschampsia, Leymus and Phragmites and has also been recorded on the sedge, Carex and the rush, Luzula. This species overwinters as a small larva.

Membranipora membranacea begins its life cycle as a plankton-feeding larva, triangular in shape. After several weeks, the larva attach to a substrate and undergo metamorphosis.Harvell, C.D., H. Caswell and P. Simpson (1990). Density effects in a colonial monoculture: experimental studies with a marine bryozoan (Membranipora membranacea L.).
Depressaria emeritella is a moth of the family Depressariidae. It is found in most of Europe. It is also found in the Near East and the eastern part of the Palearctic realm. Part of a Chrysanthemum vulgare leaf folded by larva Larva The wingspan is 22–26 mm.
The larva at first stitches together any overlapping leaves of its food plant. Later, it folds over a leaf, and finally pupates in such a folded leaf. The mature larva has a reddish head and green body, with a reddish cervical shield and a green dorsal and subdorsal line.
There it dismounts and seeks a cell occupied by a host larva. The planidium then enters the body of the host. It changes its skin and shape, then remains more or less dormant until the host larva pupates. It then emerges from the bee pupa and begins to feed.
As the larva feeds and grows within this gall, it probably undergoes five larval instar stages (the growth stages between moults). The final instar stage is reached by late October. The larva ceases feeding. It now passes into the prepupal stage, in which form it overwinters inside the gall.
It cuts the leaf from the edge towards the midrib. The part cut off is rolled up from the edge to form a cone on the underside of the leaf, then the larva continues to feed inside the cone. The larva passes two instars within this cone, or may changes the leaf to make another cone. When fully grown, the larva forms a whitish, spindle-shaped cocoon inside the cone, which has a small, round, semitransparent window on the side near the base.
The mature female wasp seeks out adult female ladybirds, although they will sometimes oviposit into a male adult or larval instar. One egg is planted in the host's soft underbelly. The wasp larva hatches after 5–7 days into a first instar larva with large mandibles and proceeds to remove any other eggs or larvae before beginning to feed on the ladybird's fat bodies and gonads. The wasp larva inside the ladybird goes through four larval instars in 18–27 days.
Female Charidotella sexpunctata lay clusters of eggs on stems and on the undersides of host leaves. A spiny, yellowish or reddish brown larva emerges from its egg in 5 through 10 days. A larva accumulates its shed skins and frass on a structure called an anal fork, which it positions over its body as a fecal shield, evidently hiding the larva from predators. This is usually effective against smaller insect predators such as ants, but not larger ones, such as hemipterans.
Emily Ashby from the organization Common Sense Media rated Larva three stars. She praised the show for showing the perspective of Red and Yellow, stating "because the characters are the size of worms, everything around them is larger than life, and that perspective is always fun to see in action." Ashby, Emily "Larva TV Review" Issac Butler of Slate described Larva as "the most terrifying show on Netflix" and mocked its excessive toilet humor in a tongue-in-cheek article.
Antlion larvae are capable of capturing and killing a variety of insects and other arthropods, and can even subdue small spiders. The projections in the jaws of the larva are hollow and through this, the larva sucks the fluids out of its victim. After the contents are consumed, the dry carcass is flicked out of the pit. The larva readies the pit once again by throwing out collapsed material from the center, steepening the pit walls to the angle of repose.
The name "Larva" is taken from Roman mythology, which like "Lemures" refers to a restless spirit of the dead. Many of the Western Shinma appearing in the second manga series also follow a naming convention drawn from various European demons and spirits. Larva's name and signature mask may also have been inspired from the white, ghostly Venetian Carnival mask "Larva," also called "Volto." In Volume 1 of the TV series, Larva was called Lava in the English dub and subtitles.
The larva bores into the stem of the alligator weed and consumes it from the inside out, generally destroying between four and eight stems before pupating. It pupates in a cocoon inside the hollowed-out stem for ten days. Alligator weed which has been attacked by the larva has areas of dead leaves distal to the point at which the larva has destroyed the stem, blocking nutrient flow. A mat of the weed can be quickly eliminated in heavy infestation.
The biology of Cydistinae larva and adult females are not known, as only adult males have been described thus far. But, given that all the known larvae and neotenic larva-like females of the closely related Rhagophthalmidae and Phengodidae are bioluminescent, live in leaf litter and soil, and feed on millipedes, the larva and females of the Cydistinae likely possess similar characteristics. The Cydistinae represent the earliest diverging lineage of the Phengodidae yet known, and are also sister to the Rhagophthalmidae.
This wasp shows a considerable degree of synchronization with its host species. When parasitizing the sunflower stem weevil, the female wasp lays a single egg into a first instar larva, which feeds just under the epidermis of the stem where it is within reach of the wasp's ovipositor. By the winter, the host larva is fully developed and enters diapause in a chamber near the base of the plant. The wasp larva, still contained within its living host, also enters diapause.
The larva is whitish and reaches when fully grown and the pupa is cream-coloured and about long.

The larva is narrow and uniformly green with a yellow, white, or pink-tinged line along each side.
The larva will then feed on the hemolymph, creating a hardened saddle. During this time, the spider goes on about its normal web building and insect-catching behavior for the next one to two weeks. In another 2-3 days the second-instar larva will hatch and insert its hook-like structure into the hemolymph saddle and completely emerges from its egg. When the larva is ready to pupate, it releases a chemical induction that causes the host to spin a special web to make a cocoon for the larva, the design of which is completely different from any it has ever made, and then to sit motionless in the middle of this web.
Sea urchins all release their eggs or sperm directly into the water column at the same time to ensure fertilization. It is not understood what causes S. droebachiensis to release their sperm or eggs, but it may have to do with temperature, because they usually reproduce in early spring. Once fertilized, the gamete grows via mitosis and eventually becomes a larva capable of simple swimming called an echinoplutes. The metamorphosis from larva to a radially symmetrical adult is hugely complex, and only some of the more basic details are included here. The larva swims to the appropriate substratum where it attaches, usually with the “left and right” sides of the larva, becoming the “mouth and anus” sides.
The eggs are laid in the axils on slender shoots (<10 mm diameter) of sallows, and the first year larva excavates a tunnel which shows no external signs of the larva. In the spring of the following year the larva can be as long as 17–18 mm and tunnels deeper into the tissue of the stem, excavating a vertical tunnel 50–75 mm long and 3 mm in diameter. By the second autumn the frass is pressed into cavities between the bark and wood, and the pear-shaped gall is noticeable. The larva feed on sallows and their hybrids; Salix aurita, S. caprea, S. repens, S. cinerea, S. alba, S. fragilis, S. daphnoides and S. rosmarinifolia.
As these devices are a common component of first-aid kits, this is an effective and easily accessible remedy. A larva has also been successfully removed by first applying several coats of nail polish to the area of the larva's entrance, weakening it by partial asphyxiation. Covering the location with adhesive tape would also result in partial asphyxiation and weakening of the larva, but is not recommended because the larva's breathing tube is fragile and would be broken during the removal of the tape, leaving most of the larva behind. Oral use of ivermectin, an antiparasitic avermectin medicine, has proved to be an effective and noninvasive treatment that leads to the spontaneous emigration of the larva.
This way the larva does not need to scan its environment by rotating. This is an adaption for living on the bottom of the sea the lifestyle of the nectochaete larva while scanning rotation is more suited for living in the open water column, the lifestyle of the trochophore larva. Phototaxis in the Platynereis dumerilii nectochaete larva has a broad spectral range which is at least covered by three opsins that are expressed by the cup eyes: Two rhabdomeric opsins and a Go-opsin. However, not every behavior that looks like phototaxis is phototaxis: Platynereis dumerilii nechtochate and metatrochophore larvae swim up first when they are stimulated with UV-light from above.
Later, the larva lives freely, creating feeding holes in the leaf near the margin, causing fleck mines. Pupation takes place in a white or yellowish-white, spindle- shaped cocoon. Larvae can be found from April to May and in July. The species probably overwinters as an egg or young larva.
Neotelphusa sequax (crepuscular rock-rose moth) is a moth of the family Gelechiidae. It is found in most of Europe and has also been recorded from North America. A shoot of Helianthemum vulgare spun together by larva Larva The wingspan is 11–14 mm. Adults are on wing in July.
Ptocheuusa inopella is a moth of the family Gelechiidae. It is found from France to Russia and from Denmark and Sweden to Austria and Hungary. It has also been recorded from Greece. A flower of Inula dysenterica with some florets disturbed by larva Larva The wingspan is 8–9 mm.
This is supported by a further discovery that the CHCs of the butterfly larva more closely resemble the CHC of the adult male ant rather than the CHC of the ant larva. The CHCs aid the caterpillars in avoiding ant aggression by allowing them to mimic colony-specific information production.
Syncopacma albipalpella is a moth of the family Gelechiidae. It is found from Germany to Spain and Italy and from Great Britain to Austria. A sprig of Genista anglica with leaves spun together and discoloured by larva Larva The wingspan is 9–11 mm.microlepidoptera.nl Adults are on wing in July.
Larva greenish, with dorsal and sublateral yellow stripes or brown with white stripes. Paired brush organs, which are used as pheromone producing hormones are found at ventral junction of femur and tibia of the hindleg. The larva is a pest which is known to attack Mimosa rubicaulis and Acacia concinna.
This organ gives the larva its common name. The most commonly encountered rat- tailed maggot is the larva of the drone fly, Eristalis tenax. It lives in stagnant, oxygen-deprived water, with a high organic content. It is fairly tolerant of pollution and can live in sewage lagoons and cesspools.
Each larva can easily eat a whole plant, and the butterfly performs an "egg-load assessment" to determine the potential competition for its larva. Leaves that have grown callosities, which strongly resemble the orange eggs of the butterfly, are less likely visited by egg- laying females, protecting the plant from herbivory.
Exaeretia culcitella is a moth of the family Depressariidae. It is found in Ireland, Germany, the Czech Republic, Austria, Slovakia, Hungary, Italy, the Republic of Macedonia and Russia. A leaf of Chrysanthemum corymbosum attacked by larva Larva Adults are on wing from June to July. The larvae feed on Chrysanthemum corymbosum.
This moth flies at night and is attracted to light, sugar and nectar-rich flowers. In the British Isles the moth is active in June and July. The larva feeds on various grasses, including reedgrasses, tussock grasses, fescues, canarygrasses, and ryes. This species overwinters as a larva, feeding during mild weather.
The third instar larva feeds on the epidermis and some mesophyll on the upper surface of the leaf. When full-grown the larva descends to the ground by silk or moves to some convenient place, and spins an elongate cocoon on the twig, the trunk or lower surface of the leaf.
The body of the larva is soft while the head capsule is hard. When it outgrows the head capsule it moults, shedding its skin. This happens four times throughout its life. At the end of the larva stage, it becomes a pupa, hanging down from the roof of the cave.
Ypsolopha ustella, the variable ypsolopha moth, is a moth of the family Ypsolophidae.mothphotographersgroup It is found in most of Europe and is also present in North America. Two leaves of hornbeam fastened together by larva Larva The wingspan is 15–20 mm.UKmoths It is a variable species with numerous colour forms.
X. sulcatipes eggs are laid in closed cells that are prepared within 1–3 days. Preparation includes pollen gathering and bee-breading. When the eggs hatch, the small larva feed on the bee-bread while remaining in the same position. A few days afterwards, the larva begin to move and molt.
The larva is blue green, turning bright green as it approaches pupation age. It has a large head capsule, yellow mandibles, and yellow longitudinal stripes down its body. It feeds on the leaves of oaks and other deciduous trees (see list below). The larva is sometimes called the green oak caterpillar.
Coleophora paripennella is a moth of the family Coleophoridae. It is found in most of Europe, except the Iberian Peninsula and Balkan Peninsula. Mined leaf of Centaurea nigra with attached larva-case Larva Larval case The wingspan is 10–13 mm. Adults are metallic bronze with white-tipped dark antennae.
A ciliated oncomiracidium emerges from the egg in 3–5 days, depending on water temperature. In warmer temperatures the embryo develops more rapidly. The larva emerges, leaving the embryonic membrane inside the egg. The larva is drawn into the gill cavity of a host fish, where it attaches by its hooks.
Larva Mortus is a 2008 video game developed by independent video game developer Rake In Grass. It is a top-down shooter. The source code of the Torque 2D based game was made available by the developer under non-commercial usage terms in 2009.Source code of Larva Mortus on rakeingrass.
The ground colour of the larva varies in shades of grey and has a pattern of black lines. It has an orange osmeterium. The larva has a large number of tubercles arranged in two lateral and two sub-dorsal rows. The third and fourth segments have an additional pair of tubercles.
If a larva fails to reach its full size, it will be prematurely expelled from the uterus. The aborted larva dies. Abortions could be due to the mother fly not obtaining enough food or also when carelessly handled or exposed to insecticide. Eggs are subjected to abortion for the same reasons.
Larva completes five instars to become a pupa. Pupa dark brown, much round with no distinguishing lumps or lobes.
The moth flies in two or three generations from April to September . The larva mainly feeds on lady's bedstraw.

It has been hypothesised that P. technica larva inhabit and consume dead leaves of large monocots or dead wood.
In this stage the mine occupies the lower layer of spongy parenchyma. The larva of the third instar feeds on the whole parenchymal tissues remaining inside the blotch-mine, then makes it into a tentiform type. After the third moult, the larva leaves the mine through a round hole and migrates to another leaf, which it cuts from the edge towards the midrib. This cut edge is rolled to form a cone on the underside of the leaf, then the larva continues to feed inside the cone.
Moth larva about to moult; the new stemmata are visible behind the old head capsule An example of a sawfly larva. It has just a single pair of stemmata, and they are set higher on its head than the position of stemmata on the heads of Lepidopteran larvae. Acherontia species shown here, is typical of the order Lepidoptera. The head of the larva bears more than one pair of stemmata, all of which are set low down and are far more widely placed than the mouthparts.
Larval shape The larva of L. trifolii are unique from those of many other flies in their shape, as the body of L. trifolii larva does not taper at the head end. The larva are uniform in thickness at both their anterior and posterior ends but additionally have a pair of spiracles at the posterior end. They do not have legs and are initially clear in color, but gradually become yellow as they mature. The larval instars are differentiable by the lengths of the body and mouthparts.
The spider does not exhibit any behaviors that are outside of its normal scope, however the usual timing of the behaviors is altered. This is because the larva is using the spider's behaviors to increase its fitness and chance of survival. By increasing the levels of hormones that promote certain actions, the larva alters the normal behavior of the spider to its advantage. The larva also has a mutualistic relationship with polydnaviruses that suppresses the immune system preventing it from making any counter-action.
After hatching, larvae of the parent bug remain in a tight aggregation, feeding on their empty egg shells. When any larva tries to abandon the aggregation, the female tilts her body, stretches her antennae to reach the larva and pushes the larva back to the aggregation. During the second and third instar they move, for food, towards catkins then back to the leaf with the female in close attendance. The female keeps a lookout for the larvae constantly and manages them with touches of her antennae.
As the larvae mature, they become increasingly aggressive. Although they have host plants surrounding them, H. zea larvae attack and eat other insects. When presented with a second-instar larva of Urbanus proteus, the corn earworm larva grasps the insect, rolls onto its side to form a semicircle, and begins feeding on the insect's posterior end. If the U. proteus begins to bite out of defense, H. zea rotates the larva 180° and uses its mandibles to puncture the head capsule, killing the insect.
The adult Profenusa thomsoni is black and about in length and fly-like in appearance. The whitish larva has short legs, dark markings on the first segment of the thorax, and two black spots on each of the second and third segments. It develops inside a leaf blade, the egg usually being laid close to the midrib and the larva hollowing out a "blotch"-shaped cavity. There are six instars, the last stage taking place on the ground as the larva searches out a place to pupate.

A piece of Peucedanum officinale leaf attacked by larva Larva The wingspan is 15–18 mm.Hants Moths Adults are on wing from July to August.
The disease presents with an eosinophilic granulomatous mass, most commonly in the posterior pole of the retina. The granulomatous mass develops around the entrapped larva, in an attempt to contain the spread of the larva. ELISA testing of intraocular fluids has been demonstrated to be of great value in diagnosing ocular toxocariasis.

The sea buckthorn moth (Gelechia hippophaella) is a moth of the family Gelechiidae. It is found from Fennoscandia to the Pyrenees, Italy and Romania and from Great Britain to Ukraine. A shoot of Hippophae rhamnoides eaten by larva Larva The wingspan is 17–21 mm. Adults are on wing from July to September.
Each larva ties together the margins of one of the terminal leaves of the host plant, to make a shelter. The larva lives and feeds as a skeletonizer inside this shelter. It is thought the larvae complete development and pupate in the shelter, and then emerge in late May or early June.
The first larval stage is called a prism. After this stage the embryo will develop two arms transforming itself into an echinopluteus larva. This is followed by the development of arms, until it reaches 8 arms all together. After this the larva develops an echinus or juvenile rudiment, which will become the juvenile.
The development of Megaselia scalaris fly is holometabolous, consisting of four distinct stages. These stages include: egg, larva, pupa, and adult. There are three distinct larval instars of M. scalaris. The third instar of development usually lasts longer than the first two because there are dramatic changes from a larva into a fly.
Larva brownish grey, dotted with red and yellow; dorsal line pale, with darker edges, but obscure; spiracular line broadly pale. They feed at first in the catkins, which are usually the first to fall. The later instars feeds on the leaves of herbaceous plants. Before pupating the larva aestivates for a few weeks.
Males are highly territorial and are known to use the same perch throughout their adult lifespans. Females lay their pale green eggs singly on the underside of host plant leaves. The larva lives in a leaf shelter by rolling or tying leaves together with silk. The larva is brown with a greenish hue.
Adults are on wing from May to July. There is one generation per year. Habitat in England Larva Larva grey brown, mottled with dark; dorsal line yellowish, black edged; a series of oblique brown subdorsal stripes; lateral lines narrowly brown. The larvae feed on various grasses, including Festuca ovina, Poa and Gramineae species.
A larva's glow attracts prey into its threads. The roof of a cave covered with larva can look remarkably like a blue starry sky at night. A hungry larva glows brighter than one that has just eaten.(citation needed) Prey include midges, mayflies, caddisflies, mosquitos, moths, and even small snails or millipedes.
The larval food plant is oak. The insect overwinters as a larva. The body of the caterpillar larva is red brown, but it camouflages itself by attaching a screen of oak leaf fragments to its specially hooked bristles. After overwintering, the attached camouflage changes and consists of bud scales from the oak tree.
The abdomen or body is composed of nine segments. In the larva it ranges from segments 5 to 13. The eleventh segment of the larva holds a pair of anal claspers, which protrude in some taxa and represent the genitalia. Many families of moths have special organs to help detect bat echolocation.
Green muscardine is caused by Nomuraea rileyi as well as Metarhizium species. Keepers of silkworms recognize symptoms such as dark brownish lesions with lighter centers on the sides and back of the larva. At death the larva turns white and within a few days it is covered in a bright green fungal coating.
Later it feeds from a tough web, retreating when disturbed. The catkins are partly or completely destroyed by the larva. If it runs out of catkins the larva bore into the base of a bud, hollowing it out and ejecting the frass which can be seen in a small pile on the bud.
The fly larva feeds on the mole cricket and eventually kills it, then the fly larva emerges from the carcass and makes its way into the soil where it pupates. The adult fly emerges from the pupa about eleven days later. It feeds on the honeydew secreted by insects such as aphids.
The adults fly at night from June to August, occasionally later, and are attracted to light. The larva is brown, tapering towards the front, and feeds on a variety of plants including bedstraw, chickweed, dandelion and knotgrass. The species overwinters as a small larva. #The flight season refers to the British Isles.
Adela violella is a moth of the Adelidae family. It is found in most of Europe, except Ireland, Great Britain, Fennoscandia, the Baltic region, Croatia, Greece and Portugal. A sprig of Hypericum perforatum harbouring larva Larva Larval case The wingspan is about 11 mm.microlepidoptera.nl Adults are on wing from June to July.
They are often found in wet, moist habitats and larva mostly feed on mosses and lichen. The larva was recorded as a minor pest of brinjal. They were observed as hosts of Glyptapanteles species of parasitoid wasps. It is highly adaptable to domestic conditions, caterpillars are found along walls in rainy seasons.
After hatching, the parasite larva kills the host larva, unless the female parasite has already done so, and then consumes the provisions. Parasitic species are of equal size or smaller than their victims. In 1921, the journal American Museum Novitates published a preliminary report on parasitic megachilid bees of the western United States.

Larva ochreous grey, paler, more greenish, at sides; lines greenish edged with black: the subspiracular line whitish and double; head with black speckling. The larva is green or brown with two white stripes down each side. It feeds on a range of plants (see list below). The species overwinters as an egg.
The larvae feed on Eriophorum angustifolium. They mine the leaves of their host plant. Initially, the larva bores into the stem of the host plant and mines the lower part of the leaf. After overwintering the larva creates a short pale reddish gallery in the lowest part of the leaf it overwintered in.

Some researchers have used kiln stilts as a settlement substrate for coral larva including those of the species Dendrogyra cylindrus.
The more the larva increases in size, the less is the secretion added by the adults, so a fourth-instar larva remains curled in the cell pushing its back against the cell walls. This is another important difference from the other social wasps where the larvae keep their body distended along the longitudinal axis of the cell and present only their heads at the cellular openings. When the adults of the hover wasps nourish their larvae, they touch with their antennae the sides of the larva which opens itself as a kind of sphincter to receive the cud of food. In the other social wasps, instead, the food is supplied by the adults directly into the mouth of the larva.
"Jump" is often an exaggeration, but the beans nonetheless do move around quite a bit. The larva may live for months inside the fruit with periods of inactivity. It eats away the seed inside the capsule, making a hollow for itself. If the fruit is cut, the larva will repair the hole with silk.
A rhabdomeric photoreceptor cell forms with a pigment cell a simple eye. A pair of these eyes mediate phototaxis in the early Platynereis dumerilii trochophore larva. In the later nectochaete larva, phototaxis is mediated by the more complex adult eyes. The adult eyes express at least three opsins: Two rhabdomeric opsins and a Go-opsin.

It flies at night from May to July and is attracted to light and sugar. The larva is purplish brown with yellow stripes and feeds internally in various grasses including Agropyron, Dactylis, Elytrigia and Poa. This species overwinters as a larva. Habitats include, forests, meadows, moors, rocky areas, park-like landscapes, steppe and settlements.
At temperatures below , even short exposures kill larva and adults. Intraspecific factors also affect life stages: cannibalism of instars in the process of moulting has been seen, though only in situations where food is scarce. Diet quality also can affect larva development; nutrient deprived larvae are more susceptible to infection by the yeast Candida albicans.
Anacampsis scintillella is a moth of the family Gelechiidae. It is found in most of Europe, except Ireland, Great Britain, the Netherlands, Norway, Finland, most of the Baltic region and Poland. A sprig of Helianthemum vulgare eaten by larva Larva The wingspan is 12–13 mm. Adults are on wing from June to August.

On Sardinia and Corsica, also on Elba. — Egg almost globular, ivory-white, minutely ribbed, the larva appearing in 14 days. The larva is ivory-yellow, with a thin, black, dorsal double line; above the spirales a black side-line, which is interrupted on each segment. Head pale brown, with black mandibles; on grass (Kollmorgen).
The green eggs are laid singly or in stacks under host plant leaves and stems. The spiny larva varies in color from pale green to yellow to white and to even black. The solitary larva feeds on leaves at night. Older larvae construct daytime leaf shelters by pulling a single leaf together with silk.
Caryocolum tricolorella is a moth of the family Gelechiidae. It is found from Fennoscandia to the Pyrenees, Alps and Romania and from Ireland to Russia and Ukraine. A sprig of Stellaria holostea with a young shoot attacked by larva Larva The wingspan is about 12 mm. Adults are on wing from June to August.
Cosmopterix schmidiella is a moth of the family Cosmopterigidae. It is found from most of Great Britain to Romania, and from Japan through central Russia to the Iberian Peninsula. It is believed to be extinct in Britain. A leaf of Vicia sepium with leaflets discoloured by larva Larva The wingspan is 9-9.5 mm.
As the larva develops, the blotch usually incorporates the earlier linear mine. The last instar larva vacates the mine for pupation by chewing a semicircular opening near the margin of the blotch. Cocoons are usually made in the leaf wrinkles. The larvae are pale green to yellowish-green and reach a length of 4 mm.
Her thesis was on the parasitoid wasp, Apanteles congregatus (now Cotesia congregata), and its host, the moth Manduca sexta, whose larva is known as the tobacco hornworm. Her subsequent research continued to focus on this interaction, using it as a model for how parasitoids can alter the physiology and behavior of the host larva.
The extremely early mine is usually epidermal, brightly whitish and transparent. When the larva consumes the parenchymal tissue within the blotchy part, it leaves the mine for a pupating site through a semicircular slit. The cocoon is small, boat-shaped, with some bubbles on the surface. The full-grown larva is reddish in body colour.
In most species, there is a swimming veliger larva with a coiled shell, but the shell is shed at metamorphosis when the larva transforms into the adult form. Some species have direct development, and the shell is shed before the animal emerges from the egg mass.Thompson, T. E. 1976. Biology of opisthobranch molluscs, vol.
Coleophora virgatella is a moth of the family Coleophoridae. It is found from Germany and Poland to the Pyrenees, Italy and Greece. It has also been recorded from southern Russia and central Asia. Mined leaf of Salvia pratensis with larva-case attached Larva Larval case Adults are on wing from late June to July.
Agonopterix heracliana is a moth of the family Depressariidae. It is found in most of Europe, North Africa, the Near East, and the eastern part of the Palearctic realm. Mating A leaf tip of Anthriscus sylvestris folded by larva Larva The wingspan is 17–25 mm. Adults are on wing from September to April.
The larva spins a cocoon and pupates. Eventually, the hatching larva will eat the prey and emerge from the nest. Adults can be seen in mid-summer feeding on nectar at flowers, especially Queen Anne's lace (Daucus carota), parsnips and water parsnips (Sium suave, Sium latifolium, Berula erecta). They have a low reproductive rate.
Not all of the brood is destroyed. In this case, the adults females malaxate the brood that they destroy and feed it to the remaining brood. During one of these events. somewhat astonishingly, an adult male P. metricus was observed to malaxate a larva and feed a fragment of this to a surviving larva.
The P. rapae larva is voracious. Once it hatches from the egg, it eats its own eggshell and then moves to eat the leaves of the host plant. It bores into the interior of the cabbage, feeding on the new sprouts. The mustard oil from the host plant makes the larva distasteful to birds.
The female lays anywhere from 30 to 80 eggs on the leaves and flowers of toadflax plants. In one to two weeks the larva emerges from the egg and begins feeding. This caterpillar undergoes five molts during a one-month period. The first- stage larva is about 5 millimeters long and dark gray in color.
They mine the leaves of their host plant. The mine starts as a small roundish blotch becoming irregular as it becomes larger from the eating of the larva within. Full-grown larvae are about 6 mm long and pale greenish. The larva emerges to spin a whitish cocoon on the surface of the leaf.
They mine the leaves of their host plant. The mine starts as a very slender corridor, gradually widening as the larva grows and becoming serpentine and towards the last enlarges to a blotch. The larva emerges to spin a whitish cocoon on the surface of the leaf. The pupal period lasts about 10 days.
The caterpillar hooks its anal prolegs into the silken lining of the bag. As it feeds and grows, the larva drags the bag wherever it goes until it is full grown and pupates. If alarmed, it shuts the opening by pulling in the slack in front. About February or March the larva is fully grown.
The larva go through six different instars, each varying slightly in physical appearance and pattern. The larva process lasts from 14 to 30 days, again depending on temperatures. The mature caterpillar is about 1.5–2.0 inches (38–51 mm) in length. This is the most destructive life stage as the larvae have biting mouth parts.
In insect physiology, the corpus allatum (plural: corpora allata) is an endocrine gland which generates juvenile hormone; as such, it plays a crucial role in metamorphosis. Surgical removal of the corpora allata (an allatectomy) can cause an immature larva to pupate at its next molt, resulting in a miniature adult.Vitamins and Hormones: v. 14: Advances in Research and Applications, edited by Richard Harris, 1956, from Elsevier Similarly, transplantation of corpora allata from a young larva to a fully mature larva can greatly extend the larval stage, resulting in an equivalent to gigantism.
The larva lives largely underground, and feeds on similar prey to the adult and has the same well-developed mandibles. It adopts the same display with open jaws and raised tail when threatened. The larva goes through three stages of growth (instars), the final stage ranging from 20 to 26 mm in length. Around 150 days old, the larva pupates for about 35 days and emerges as an adult with its final colouring, fully formed except for the wings which cannot be folded neatly beneath the elytra for several hours.
Currently, there is only one study of larval Ipnops. This study found the larva in shallower depths (1600m) which suggest larvae move to the surface during their development and return to the depths once they are adults The larva also had very large eyes and no presence of the membrane which covers adult Ipnops eyes. This indicates that as larva develop, they lose their sense of sight and their eyeballs transition into the photosensitive plates. However, this is purely hypothetical and more studies need to be conducted before the scientific community can be certain.
In the third and fourth instars, the larva which has been transformed into tissue-feeding type, feeds on the remaining tissues within the blotch-mine. The tissues are consumed by the fourth instar larva, thus the upper epidermis of the mining part is completely separated from the lower and turns pale or deep brown in colour. The fully matured mine is slightly contorted by larval silken threads into a tentiform one. The fifth instar larva leaves the mine and migrates to another leaf, which is usually located more distally on the branch.
The family Halictidae contains a few social parasites and cleptoparasitic bee genera, and these parasites affect the genus Augochlorella as well. Some prominent cleptoparasites include Sphecodes (like Sphecodes pimpinellae), Microsphecodes, and some Lasioglossum species. Sphecodes females will typically kill the existing Augochlorella egg or larva in the cell before they lay their own egg. In most other cleptoparasitic species, eggs are laid on the unfinished cell walls or through sealed cells where the cleptoparasite larva will kill the existing egg or larva and eat the host's stored food.
The typical protonymphon larva is most common, is free living and gradually turns into an adult. The encysted larva is a parasite that hatches from the egg and finds a host in the shape of a polyp colony where it burrows into and turns into a cyst, and will not leave the host before it has turned into a young juvenile. Little is known about the development of the atypical protonymphon larva. The adults are free living, while the larvae and the juveniles are living on or inside temporary hosts such as polychaetes and clams.

Nor does it have an otolith, a sensory organ connected with balance, which the former possesses. Molgula occulta hatches into a tailless larva from the chorion in twelve hours and develops four ampullae or dilatations immediately before metamorphosing into a juvenile. It appears that the tailed larva is the ancestral state in the Molgulidae and that loss of the tail has occurred on at least four separate occasions independently. Without tail or otolith, the larva is unable to swim or orient itself and so is unable to disperse to new locations.
The larva feeds on the tissues of the gall and molts twice before excavating a narrow exit tunnel out of the gall in mid-September. After digging its tunnel, without actually opening up the gall to the outside, the larva overwinters and, if it survives, molts into an adult and leaves the gall the following spring. A number of predators and parasites prey on the larvae of E. solidaginis. The black-capped chickadee (Parus atricapillus) and the downy woodpecker (Picoides pubescens) target large galls, breaking them open and removing the larva living inside.
Larva, Michigan, mid-August Underside of larva, showing reduced legs The larva is distinctive, with no close analogues, although it may be mistaken for the shed skin of a hairy spider or leaf debris. It has six pairs of curly projections, three long and three short from the flattened body, each densely covered in hairs. According to David L. Wagner, who experimented on himself, the hairs do not sting, contrary to popular belief. However, susceptibility can vary among humans and it may produce a reaction in some people.
Treatment typically consists of removal of the larva and then prevention of secondary bacterial infections. If the warble is accessible, a specialist can remove the larva by depositing petroleum jelly over the breathing hole of the parasite; this causes the larva to emerge for air and enable easier removal by the specialist. Larvae within or near the eye will sometimes require surgery for removal. Larvae that die within the vitreous humor of the eye do not need to be removed, they will be broken down and absorbed by natural chemical processes within the host.
He uses magic as well as a human- turned-into-Shinma whose soul is trapped inside of a gigantic samurai armor, managing to seal Larva inside of a wall. Miyu believed that Lemures wanted to target her to become leader of the Shinma, so with Himiko's help she faced him. However Larva broke Lemures's spell when Miyu was captured and injured by Lemures's puppet Shinma, then he stayed true to Miyu. Instead of banishing Lemures to "The Darkness," a very angry Miyu killed him with fire as a punishment for abducting and harming Larva.
It adopts a particular posture when encountered by a meat ant, raising the anterior half of the body and curling its posterior over its back to expose the anus. Following inspection, a meat ant will carry the larva into the nest, where it becomes a predator on the ant larvae. In the nest, the larva continues to produce an anal secretion that is attractive to the ants. Once the larva has completed development, which may take weeks or possibly months, it emerges from the ant nest, and spins its cocoon in a protected spot nearby.
A brooding female Reproduction of the winged mapleleaf is very similar to that of many other freshwater mussels. The males release their sperm into the water, then as the females siphon in water the sperm fertilizes the eggs which are located on their gills. After fertilization the eggs develop into a larva, and once the larva reaches a certain stage it is released from the gills of the mother mussel into the river current. The larva then must reach the gills of a host fish where it can then continue its growing process.
The larvae have an exclusively parasitic life, primarily in the nests of solitary bees, or sometimes of locusts. If the larvae have inadvertently selected a honey bee, they die in the hive and may cause serious damage. When the host female bee lays eggs in its cells, the first-stage larva of the violet oil beetle eats the eggs of the bee, increases in volume and becomes the second-stage larva, which continues its development eating honey and pollen. The larva, after other two stages, forms the nymph and finally the imago.
Most insects, especially aquatic insects, have shown to have fluctuation in their oxygen consumption due to the weight and size of the organism, the temperature and/or chemistry of the water or the season of the year it is. Year round presence of N. serricomis larva in streams results in generally stable respiratory responses to temperature.Physiologically, N. serricomis larva are adapted to maintain a constant oxygen consumption regardless of temperature, season or stage of larval development. This consistency allows N. serricomis larva to vary its metabolism in direct relation to its surrounding water temperature.
The larva bores through the stomach wall and migrates around in the host's body for about three months before returning to the stomach and attaching itself in the gastric mucosa. It then takes another six months to mature. The eggs are carried in the host's feces, and if they reach fresh water the cycle begins again. As humans are not a normal host for the larva, they do not mature in humans, but can cause various degrees of damage, depending on where the larva wanders in the body.
In some species the egg is possibly laid into the tunnel of the host if the host itself can not be reached, and the orussid larva itself crawls to the host. On its way to the host it may gnaw through the wood shavings left by the host. It has been disputed whether this material contributes to the nutrition of the larva. At least in Guiglia schauinslandi, the larva lives externally for its first two instars and then enters the putrid(?) liquid in the dead host, where it remains until the adult emerges.
Pick a stone out of the stream and observe the larva of the black fly as they cling to the stone and filter food from the water. Although the adult black fly is considered a pest, the presence of its larva in the stream is an indicator of good water quality. The black fly larva and the diversity of the other aquatic life found in the stream indicate good water quality, but the stream is vulnerable. Chemical tests reveal low pH and alkalinity levels due to the geology and vegetation of the area.
The life cycle of nematomorphs has 4 stages: First is the egg, which takes about 10–12 days to complete its larval development after being laid. Second is the pre-parasitic larva that hatches from the egg; the fully developed larva remains in the egg 7–10 days before hatching. Third is the parasitic larva that develops within an invertebrate host; larvae swim about freely in the water after hatching, and are ingested with water when insects drink. If the larvae does not find a host within a few days, they will die.
The larva feeds mainly in the direction of the main axis. It is especially abundant on the sunny side of trees.
The larva and pupa of C. perturbans are small and contain a siphon modified for respiration through underwater, aquatic plant life.

The larva of the first instar bores into the bud. Later intars feed on flowers and fresh leaves. Pupation takes place inside a shelter which the larva nibble out of the bark.
G. mellonella larvae parasitize wild honeybees. Eggs are laid within the hive, and the larva that hatch tunnel through the honeycombs that contain honeybee larva and their honey stores. The tunnels they create are lined with silk, which entangles and starves emerging bees, a phenomenon known as galleriasis. Tunnels also result in massive destruction of the combs.

In spite of these similarities following differences present between these two groups show that these groups are not closely related: :a) Absence of gill-slits in Phoronis. :b) Presence of lateral nerve cord in Phoronis. :c) Formation of coelom by splitting of the mesoderm in Phoronis (schizocoelic).
The medical signs in human gnathostomiasis are caused by migration of the immature worms (L3s). Migration in the subcutaneous tissues causes intermittent, migratory, painful, pruritic swellings (cutaneous larva migrans). Migration to other tissues (visceral larva migrans), can result in cough, hematuria, and ocular involvement, with the most serious manifestations eosinophilic meningitis with myeloencephalitis. High eosinophilia is present.

It prefers moist areas. These include, for example, meadows, moors, wet heath and fen, woodland areas, sometimes sandy soils, but not strongly xerothermic habitats. The larva feeds internally on the stems of various grasses (including Carex species, Luzula luzoloides, Bracilypodium sylvaticum and Poa pratensis), pupating in a cocoon among the roots. This species overwinters as a larva.
The parasitic wasp Hymenoepimecis argyraphaga grows its larvae on spiders of the species Leucauge argyra. Shortly before killing its host the larva injects it with a chemical that changes its weaving behavior, causing it to weave a strong, cocoon-like structure. The larva then kills the spider and enters the cocoon to pupate. Ladybug guarding a Dinocampus coccinellae cocoon.
The larva have a pale, yellowish green body, a slightly orange-brown head and a prothoracic shield (the plate of the first thoracic segment just behind the head). The prothoracic shield has light gray margins on the sides. There are many small, dark green spots conspicuously displayed along the body. The larva grow up to 7 mm long.
A number of various vertebrates, including humans, and some invertebrates can become infected by Toxocara canis. Humans are infected, like other paratenic hosts, by ingestion of embryonated T. canis eggs. The disease caused by migrating T. canis larvae (toxocariasis) results in visceralis larva migrans and ocularis larva migrans. Clinically infected people have helminth infection and rarely blindness.
The moth flies from May to July depending on the location. Larva dull yellowish green, mottled with orange and reddish brown; dorsum with a row of dark V-shaped markings; spiracular line reddish brown. The larva mainly feed on a wide variety of various trees, bushes and herbaceous plants: Betulaceae, Umbelliferae, Ranunculaceae, Cruciferae, Salicaceae, Dennstaedtiaceae, Crassulaceae, Urticaceae, Ericaceae, etc.
They mine the leaves of their host plant. The mine consists of a slender gallery that eventually enters a petiole, from where it enters a bud. The larva hibernates in the bud, that is eaten out in spring. Then the larva bores in a young shoot, sometimes diverting into a leaf that then is completely mined out.

The larvae feed on Arctium lappa, Carduus, Carlina, Centaurea jacea, Centaurea nigra, Centaurea scabiosa, Cirsium vulgare, Knautia, Serratula tinctoria and Sonchus.
Once the larva has consumed the egg and stored nectar and pollen from a bee's nest, they leave it. They then moult again, and emerge with their back legs formed. From this stage they pupate, and emerge from the chrysalis as adults. If a larva accidentally selects a honey bee as host, it dies in the hive.
They are elongated fish, although not as much so as the true eels. They typically feed on slow- moving or sessile animals, such as molluscs, echinoderms, and sea anemones. Like the true eels, they have a leptocephalus larva that floats in the surface waters before transforming into an adult. Unusually, the larva can often be larger than the adult.
Sprig of broom with attached larva-case Larva The larvae feed on Chamaecytisus supinus, Coronilla, Cytisus scoparius, Genista pilosa, Genista tinctoria, Laburnum anagyroides, Lembotropis nigricans and Spartium junceum. They create an untidy lobe case of 7–8 mm composed of large leaf fragments. The mouth angle is about 45°. Larvae can be found up to June.
This species engages in trophallaxis with the larvae. Regardless of the attributes and conditions of each larva, they are fed roughly the same amount of liquid food. The rate of trophallaxis may increase with larval food deprivation, but such increase depends on the size of each larva. Larvae that are fed regularly tend to be given small amounts.
As a parasitoid, the M. multispinosus larva will remain attached to the ant pupa until adult stage of development, which is usually where the ant pupa will die. The life cycle, on average, lasts for about 30 days from larva to adult. Females will form 7 days after copulation and the larvae will form 37 days later.

It is found in southern France and Spain and from Slovakia and Hungary to Bulgaria and southern Russia. leaf of Vicia cracca eaten by the larva Larva Larval case The larvae feed on Vicia cracca. They create a large, blackish pistol case, almost entirely covered by a transparent pallium.
The larva hatches from the egg at the point it is attached to the pod and burrows into the pod, where it develops and feeds on the seeds. The larva is one to two millimeters long and gelatinous white. It pupates in the seed coat. When the seed pod ripens and splits open, adult weevils emerge.
Initially the larva simply extend the tunnels of the parents. These extensions differ from the parents in that the tunnels are concave rather than flat. During this time, the larvae grow bigger in size and begin to take on some adult features. After a period of several months, the larva excavate pupal chambers within the tree.
The adult feeds on gorse by digging into the soft tissue of the stem and spines with its snout, creating characteristic round holes as evidence. The larva does more damage, however. It emerges from its egg inside the gorse seed pod and feeds on the seeds for six to eight weeks. The larva then pupates for about two months.
It has large recurved antennae. The female lays about 80 eggs, depositing each at the base of a flower head. In about ten days the larva emerges and burrows into the flower head where it feeds on the developing seeds and florets. The larva is a small, plump white grub with a dark head and visible body segments.
The female lays eggs on the flower heads at an early stage of development and stem tips. Upon emergence the larva burrows into the flower head or makes its way there by tunneling through the stem. It feeds upon the developing seeds, often consuming them entirely. If any other insects invade the flower head, the larva attacks them.
The larva emerges and feeds on the roots of the plant, while the adult eats the leaves and flowers of the plant. Both larva and adult inflict damage on the plant by feeding. In its native range this beetle feeds on leafy spurge and other closely related plants. It is not known to attack other types of plants.
They create a stem gall. One or more galls may occur per stem, but only one larva inhabits each gall. The galls occur low on the stem. When full-grown, the larva chews a tunnel outwardly through almost the entire wall of the gall, leaving only the external epidermal layer as a round, externally visible window.
After mating, the gravid female creates a burrow where they bring pollen. On top of the pollen, one egg is laid. This is consumed by the larva over 10 days, after which the larva overwinters and pupates in the next year. Many melittids (such as Macropis) possess specialized morphology that allow them to collect floral oil.
After fertilization, S. officinalis embryos develop in choanosomal tissue of the female sponge. Cleavage of cells begins after fertilization, around November, and is total and equal. By May, a stereoblastula, or a blastula without a clear central cavity, forms. From May to July, parenchymella larva, or larva which is a mass of cells enveloped in flagellated cells, develop.
By the 34rd day, the larva is crawling about using its foot and its cilia. Metamorphosis takes place on about the 40th day. Over the course of 48 hours, the internal organs undergo a 90° rotation, the valves, hinge and ligament appear and the gills lengthen. A swimming veliger larva has become a benthic juvenile scallop.

Part of scabious head with larva and larval case Larva The wingspan is .microlepidoptera.nl Adult males have antennae which are almost twice the wing length, while those of the female are just over one wing length.
Cyclosa argenteoalba builds two types of web, a traditional sticky spider web, and a resting web that consists of just a few strands. When infected with a larva of the wasp Reclinervellus nielseni, the spider switches on the behavior to build a resting web. The larva then eats the spider and uses the web to complete metamorphosis.
The metamorphosis from active larva to an adult with a different body structure permits the dual lifestyle of parasitic larva, freeliving adult in this group. These relationships are shown on the phylogenetic tree; groups containing parasitoids are shown in boldface, e.g. Coleoptera, with the number of times parasitoidism evolved in the group in parentheses, e.g. (10 clades).
The invading larva may induce the plant to form a bulbous tissue mass called a gall around it, upon which the larva then feeds. Various parasitoid wasps find these galls and lay eggs in the larvae, penetrating the bulb with their ovipositors. Woodpeckers are known to peck open the galls and eat the insects in the center.

For reasons which we will not pause here to discuss, we have always regarded the eruciform type of larva as the highest.
Within a few minutes of seizing its prey with its jaws and injecting it with venom and enzymes, it begins to suck out the digestion products. The larva is extremely sensitive to ground vibrations, the low-frequency sounds made by an insect crawling across the ground; the larva locates the source of the vibrations by the differences in timing of the arrival of waves detected by receptors, tufts of hairs on the sides of the two hindmost thoracic segments. Antlion larva extracted from sand pit In trap-building species, an average- sized larva digs a pit about 2 in (5 cm) deep and 3 in (7.5 cm) wide at the edge. This behavior has also been observed in the Vermileonidae (Diptera), whose larvae dig the same sort of pit to feed on ants.

The zoaea larva can be recognized by the flattened blade at the end of the telson, the smooth rostrum and the sessile eyes.
Glossosomatid larvae, unlike other related families within Spicipalpia, build cases during the larva's first instar and each time the larva outgrows the case. Cases are formed from large and small pebbles found within streams; these pebbles are spliced together with pieces of silk created by the larva. The case is formed loosely so as to allow water, and dissolved oxygen, to flow freely into the case for larval respiration. There are a couple of reasons why larvae produce cases: # Physical protection from predators # Camouflage # Water resistance Larva are usually found in fast flowing, cool mountain springs.
The larva attaches stone weights to the top of the operculum, assisting in the closing of the operculum. The larva must enlarge its case several times as it grows to maturity. Each time it extends the case it must remove the stone weights from the top of the operculum, push the operculum upward and incorporate it into the structure of the roof, build a new operculum, and attach a new set of stone weights. When full-grown, the larva uses silk to attach the case by the head end to the rock, and it then hangs tail downward to pupate.
A sessile mollusc, the small giant clam attaches itself to rocks or dead coral and siphons water through its body, filtering it for phytoplankton, as well as extracting oxygen with its gills. However, it does not need to filter-feed as much as other clams since it obtains most of the nutrients it requires from tiny photosynthetic algae known as zooxanthellae. Beginning life as a tiny fertilised egg, the small giant clam hatches within 12 hours, becoming a free-swimming larva. This larva then develops into another, more developed, larva which is capable of filter-feeding.
Harry Edvin "Harri" Larva (born Lagerström, 9 September 1906 – 15 November 1980) was a Finnish athlete who won the 1500 m race at the 1928 Summer Olympics. He never excelled in this event nationally and was the Finnish champion in the 800 m in 1928–1930 and 1934. Larva finished 10th in the 1500 m at the 1932 Summer Olympics. Larva was requested to change his last name in 1928 by Urho Kekkonen, then president of Finnish Athletics Union and later president of Finland, who thought that his birth name Lagerström did not sound Finnish enough.
Finally in the fourth OVA, she wears a very heavy black kimono and also wears a mask. However in the TV series, she only wears two types of clothing: the typical Japanese school uniform (there were two versions seen in the anime) and the kimono known by all fans and that is shown on box covers. ; : Larva (OVA) : Larva (anime) : A gorgeous Shinma from the western world. In the OVA, Larva comes to prevent Miyu's vampire blood from awakening and kill her, but he inadvertently triggers it and she drinks his blood when he drops his guard.
Laser ablation is used in science to destroy nerves and other tissues to study their function. For example, a species of pond snail, Helisoma trivolvis, can have their sensory neurons laser ablated off when the snail is still an embryo to prevent use of those nerves. Another example is the trochophore larva of Platynereis dumerilii, where the larval eye was ablated and the larvae was not phototactic, anymore. However phototaxis in the nectochaete larva of Platynereis dumerilii is not mediated by the larval eyes, because the larva is still phototactic, even if the larval eyes are ablated.
Similarly, a new anus forms on the right side, which becomes the upper, or aboral, surface. The coelom, or body cavity is divided into three chambers in the larva, two of which form the water vascular system, while the other remains as the adult body cavity. Once the tube feet develop from the water vascular system, the larva frees itself from the bottom. At around the same time, the skeleton begins to develop, initially in a ring around the anus; at this point the larva has developed into an adult, although it will continue to grow for some years before reaching sexual maturity.
A week after the egg has been laid, the larva hatches and begins to feed on the leaf bud tissue. This activity stimulates (in a way not yet understood) the development by the host plant of enlarged 'nutritive' cells in the area around the growing larva. These are fed on by the larva and are continually replaced by new cells. Further concentric layers of tissues develop around the core nutritive tissue and come to form the structure known as the bedeguar, complete with the outermost and characteristic fibrous outgrowths that give the gall its alternative name of Robin's pincushion.
The female fly will produce a single larvae at a time, retaining the larva internally until it is ready to pupate. The larva feeds on the secretions of a milk gland in the uterus of the female. After three larval instars, a white pre-pupa which immediately forms a hard dark puparium. The pupa is usually deposited where the deer slept overnight.
The nectochaete larva already has three segments, each with a pair of parapodia bearing chaetae, which serve for locomotion. The nectochaete larva can switch from positive to negative phototaxis. After five to seven days, the larvae start feeding and develop on their own speed, depending on food supply. After three to four weeks, when six segments have formed, the head is formed.
Agonopterix kaekeritziana is a moth of the family Depressariidae. It is found in most of Europe (except the southern part of the Balkan Peninsula and Portugal) east to the Near East and the eastern part of the Palearctic realm. A shoot of Centaurea nigra folded by larva Larva The wingspan is 19–23 mm. Adults are on wing from July to September.
The adult mammoth wasps feed on nectar from flowers. In Malta they have been associated with wild artichoke and Carpobrotus edulis. The female hunts in dead wood for the grubs of the European rhinoceros beetle which it paralyses by stinging it and then lays a single egg on the larva. The larval wasp consumes the beetle larva apart from its skin.
Apanteles galleriae parasitizes G. mellonella larva inside the beehive. 1-2 eggs are laid by the adult Apanteles galleriae on each larva, though only one succeeds in parasitizing the host and surviving. The parasite emerges and ruptures the host body, and pupates into a small cocoon. Parasitism increases gradually, starting in February, reaching its peak in May, then declining until July.
P. alcon larvae are sought underground by the Ichneumon eumerus wasp. On detecting a P. alcon larva the wasp enters the nest and sprays a pheromone that causes the ants to attack each other. In the resulting confusion the wasp locates the butterfly larva and injects it with its eggs. On pupation, the wasp eggs hatch and consume the chrysalis from the inside.
This moth flies at night and is attracted to light and sugar. Its flight season in the British Isles is June through August. Larva pinkish ochreous with a pale lateral line; the tubercles black; head yellow brown; thoracic and anal plates black brown.

In another week it moults and assumes the appearance of a scarabaeid larva – the scarabaeidoid stage. Its penultimate larval stage is the pseudo-pupa or the coarcate larva, which will overwinter and pupate until the next spring. The larval period can vary widely. A fungus feeding staphylinid Phanerota fasciata undergoes three moults in 3.2 days at room temperature while Anisotoma sp.
Parasa pygmy is a moth of the family Limacodidae. It is found in Taiwan, inhabiting mountains, at altitudes ranging from 2,000 to 3,000 meters. Larva Larva Adult male The wingspan is 24–25 mm. The forewing ground colour is chestnut with a large median green patch delimited externally by a thin white line, which in turn is lined by a brown border.
Their three distinct levels of development usually occur in varying habitats. The first stage, the leptocephalus stage, or stage one, is completed after 20–30 days. It takes place in clear, warm oceanic waters, usually within 10–20 m of the surface. The leptocephalus shrinks as it develops into a larva; the most shrunken larva, stage two, develops by day 70.
Young instar larva are very similar to that of Conopomorpha flueggella. Mature larva are 5–6.5 mm. The head capsule is brownish yellow and the median two-thirds of each segment on the thorax and abdomen is dark red while the anterior and posterior ends are white. The thoracic segments are slightly blue and there are blue spots on the abdominal segments.
It represents the type of basis of all larva forms of the Eleutherozoa, to which the sea-stars, sea-hedgehog, sea- rollers and sand stars belong. The Dipleurula is a bilaterally symmetrical, ciliated echinoderm larva. Dipleurula represents an ancestral form for these primitive deuterostomes. We can see that all well-known forms of larvae of Echinodermata are derived from the hypothetical dipleurula.
It is transmitted by sap as well as a host of insect vectors. The most prominent of these are in the Phyllotreta and Psylliodes genera of flea beetles, although Phaedon cochleariae and its larva have also been known to help spread this virus. The larva lose their ability to transmit the disease once they reach the pupal stage, suggesting a mechanical infection process.
These factors are part of a complex phenomenon termed Island syndrome. With less predation and competition for resources, selection favored overdevelopment of these species. Reduced litter sizes enable overdevelopment of their bodies into larger ones. A 1901 comparison of a frog tadpole (a vertebrate) and a tunicate larva; in 1928 Walter Garstang proposed that vertebrates derived from such a larva by neoteny.
Agonopterix angelicella is a moth of the family Depressariidae. It is found in most of Europe, except the Iberian Peninsula and south-eastern Europe. It is also found on the Russian plain and Siberia (the West Siberian Lowland and South Siberian Mountains) and in Japan. A leaf of Angelica sylvestris inhabited by larva Larva The wingspan is 16–21 mm.
Beauveria bassiana, a threat to the S. myopaeformis, seen growing on an Ithominae larva Bacillus thuringiensis, a threat to larvae The parasitoid Liotryphan crassiseta is a significant cause of mortality in S. myopaeformis.Nematodes, Steinernema sp., are a threat to larvae, and larva mortality following exposure to the fungi Beauveria bassiana and Metarhizium brunneum is common. Bacteria are another threat to larvae.
The growth and development of P. tibialis is fairly unique in that a single egg is laid inside of a Hymenopteran host. After hatching, the larva parasitizes the nutrients of the host in order to grow and develop through three instar stages. The host eventually dies and the larva then pupates inside of the corpse until its emergence as an adult fly.
The larva is black with transverse white stripes. The head, part of the thorax, the area near the end of the abdomen, and the prolegs are a reddish-orange color. The larva makes a leaf shelter in new foliage by taking the leaf edges and pulling them upward and then tying them together with silk. The pupa hibernates in wood or dense peat.
It is thought that groups of stars use environmental signals to coordinate spawning to increase the chances of fertilization. Once fertilization has occurred, the zygote develops into a planktonic larva which feeds on small algae. The larva proceeds through several developmental phases. It becomes a gastrula in 2 to 3 days, a bipinnaria in 5 days, and finally a brachiolaria.
Coleophora wockeella is a moth of the family Coleophoridae. It is found from Latvia to the Iberian Peninsula, Italy and Albania and from Great Britain to southern Russia. Mined leaf of Betonica officinalis with a larva-case attached Larva The wingspan is about 20 mm. Adults are ochreous with several whitish streaks on the forewing and distinctively thickened bases to the antennae.
Once settled, the larva creates areas of swelling in the subcutaneous skin layer of their host. These swellings, known as warbles, are located between the anus and genital organs of the host. They last the same amount of time that the larva spends in its larval stage (3.5-4 weeks). The warble consists of a pore, a cavity, and a capsule.
A light Toxocara burden is thought to induce a low immune response, allowing a larva to enter the host's eye. Although there have been cases of concurrent OLM and VLM, these are extremely exceptional. OLM often occurs in just one eye and from a single larva migrating into and encysting within the orbit. Loss of vision occurs over days or weeks.
Leptocephalus larva. Leptocephalus (meaning "slim head") is the flat and transparent larva of the eel, marine eels, and other members of the superorder Elopomorpha. This is one of the most diverse groups of teleosts, containing 801 species in 4 orders, 24 families, and 156 genera. This group is thought to have arisen in the Cretaceous period over 140 million years ago.
Coleophora milvipennis is a moth of the family Coleophoridae.

The larva reaches sexual maturity about ten days later.Animal Parasites Their Life Cycles and Ecology Summer is the season of peak infestation, and by fall the worms are scarce. Eggs released late in the season enter diapause, a period of inactivity.
Coleophora ochripennella is a species of moth from the family Coleophoridae. It is found from Germany and Poland to the Pyrenees, Italy and Greece. Sprig of Ballota nigra with a larva-case attached Larva The larvae feed on Ballota nigra, Glechoma hederacea, Lamium album, Lamium purpureum, Stachys officinalis and Stachys sylvatica. They create a hairy, slender, largely dark brown lobe case of long.
The complete larvae stage takes approximately 21 days. After fertilization there are seven stages of larva metamorphosis: cleavage, blastocyst, gastrulation, auricularia (subdivided in early, mid, late), doliolaria (mid metamorphic stage pre settlement), penttactula and the last settled sea cucumber larva, visible to the naked human eye, which develops into the final organism.Morgan, A. 2009.

Sprig of “Gnaphalium arenarium” (=Helichrysum arenarium) with two larva-cases attached Larva Larval case The wingspan is 9–12 mm.Arfaktablad om Coleophora gnaphalii Adults are on wing from July to August.
Larva Larvae come in two different color phases; a green phase, and a dark phase which differs in shades of brown, orange, and somewhat of a pinkish brown. Larvae complete all five instars within approximately one month. The first instar is the same shade of green as its egg. As the larva progresses through its instars, change in structure is noticeable.
Metamorphosis occurs completely within the host egg. They are peculiar for insects which exhibit complete metamorphosis (holometabolism) in that they produce two distinct kinds of larval instars before pupation. In some fairyflies, such as Anaphes, the first instar is a highly mobile "mymmariform" larva. The second instar, however, is a completely immobile, sac-like larva without discernible segments, spines, or setae.
The abdomen is usually constricted in the basal part. The larva is slender, tapering at the front end, and smooth except for ventral creeping welts. The larva is amphipneustic: it has two pairs of spiracles, one toward the head and one at the tail. The bulbous posterior end with its pair of spiracles distinguishes it from the larvae of other acalyptrates.
The larva emerges and burrows into the flower head where it feeds on the developing seeds. The larva damages the plant by reducing seed production (all of the seeds of diffuse knapweed and 25-100% of spotted knapweed) and the adult does damage by defoliating the plant as it feeds on the leaves prior to flowering.Wilson, L.M., Randall, C.B., 2003.
The maggot then hatches and burrows through the surface of the host. After infection, Lespesia archippivora maggots go through three larval instars, exit their hosts as a late stage larva and hide under soil substrate. While residing inside its host, the maggot moves freely. After 3 days, the fly larva adheres itself close to a spiracle (breathing tube) of the infected caterpillar.
The white larva emerges in about two weeks and feeds on the roots and root hairs. It is active through the fall and winter until the cold stimulates it to pupate. It burrows into the soil to undergo a three-week pupation. Damage to the plant occurs when the larva eats the roots and the adult feeds on the leaves and flowers.
These larvae are released from the adult from June to July. Like all sponges, S. officinalis larvae are lecithotrophic, meaning they cannot feed as larva and instead rely on energy reserves provided by the mother. Therefore, they only remain as a free-floating larva for a short period before settling on a benthic surface where they grow into an adult sponge.
C. ohlone complete their life cycle in two, in rare cases take one, years. After mating and subsequent fertilization, the female tiger beetle deposits the egg several millimeters under the ground. The egg hatches into a larva that creates a burrow. The larva will feed on prey that pass by the burrow until it forms a pupa and finally emerges as an adult .
Larvae are initially fed with royal jelly produced by worker bees, later switching to honey and pollen. The exception is a larva fed solely on royal jelly, which will develop into a queen bee. The larva undergoes several moultings before spinning a cocoon within the cell, and pupating. #Young worker bees, sometimes called "nurse bees", clean the hive and feed the larvae.

It is found in China,Check List of the Tribe Tortricini (Lepidoptera: Tortricidae) in Northeast china, with Two Newly Recorded Species from China most of Europe and has also been recorded from North America.mothphotographersgroup Larva Larva feeding beneath webbing The wingspan is 14–18 mm. It is a very variable species.
Mezcal worms A mezcal worm is an insect larva found in some types of mezcal produced in Oaxaca, Mexico. The larva is usually either a gusano rojo ("red worm") or a chinicuil ("maguey worm"), the caterpillar of the Comadia redtenbacheri moth. The red worm is typically considered tastier. Contrary to popular belief, a true tequila does not contain a worm.
The female lays up to 240 cylindrical eggs beneath the bracts on the flower heads of yellow starthistle. The larva emerges and tunnels into the flower head, where it feeds on developing seeds. A larva might destroy up to 90% of the developing seeds inside a given flower head. It overwinters inside the head and pupates into an adult fly.
Like other Papilio species the larva can evert a two-pronged horn-like osmeterium when it is irritated. The osmeterium secretes an unpleasant-smelling liquid which is believed to repel predators and parasites. After the first moult the caterpillar has the appearance of a shiny bird dropping. The larva is grass green in colour, mottled black and white and smoky grey.
The larva inside the egg becomes fully developed in about one month after being laid and then enters diapause to overwinter. The egg is in the overwintering stage lasting for eight or nine months. Development ceases in preparation for the winter. After an acclimation stage, during which the larva inside the egg reduces its water content, eggs can withstand freezing temperatures.
In this genus, the host is a bee, and each species of Meloe may attack only a single species or genus of bees; while sometimes considered parasitoids, it appears that in general, the Meloe larva consumes the bee larva along with its provisions, and can often survive on the provisions alone, thus they do not truly qualified (see Parasitoid for definition).
Two species of sawfly create similar galls on dwarf willow and the galls can only be told apart by examining the larva. The larvae of E. herbaceae have black spots (easiest to see in young larva) while the larvae of E. aquilonis does not. This species along with E. crassipes and E. arbusculae are part of the Euura crassipes subgroup.
After two days, the yolk sac is gone and the fish are in a larva state and eat plankton. These fish grow very quickly.
Larva is an elongated semi-looper. Tubercles absent. Head is pale ochreous with black spots. Body with longitudinal red lines dorsally and dorso-laterally.
Larva remain in the marsupium about 12 months, and the animals continue growing for several years, reaching a final length of 10-20 mm.
They are attributed to be involved in differential development of queen larva and worker larvae, thus establishing division of labour in the bee colony.
This host plant is a favored plant for two reasons: it provides adult nutrition, as well as food for the larva after it hatches.
It is attracted to light and does not come to flowers, and its larva inhabit the stems and roots of the species' food plants.
The full nature of their trophic regime and its mechanisms are not fully known, but all larva stages are predators same as adult stage.

When a larva settles on a whale bone, it turns into a female; when a larva settles on or in a female, it turns into a dwarf male. One female Osedax can carry more than 200 of these male individuals in its oviduct. # Sulfophilic stage: Further decomposition of bones and seawater sulfate reduction happen at this stage. Bacteria create a sulphide-rich environment analogous to hydrothermal vents.

Leaf of maple, with a portion rolled into a cone by the larva Larva The wingspan is 10–12 mm. Adults are on wing from late July to October and again, after hibernating, until May.
These features make ctenophores capable of increasing their populations very quickly. Members of the Lobata and Cydippida also have a reproduction form called dissogeny; two sexually mature stages, first as larva and later as juveniles and adults. During their time as larva they are capable of releasing gametes periodically. After their reproductive larval period is over they will not produce more gametes again until after metamorphosis.
Lifecyle of Ornithodoros soft tick Argasidae soft ticks have different lifecycles from Ixodidae hard ticks, and these are very variable between species. Typically, in Ornithodoros, a larva hatches from an egg laid in the nest or resting place of the host. The larva does not feed, but directly molts into the first nymph stage. This stage feeds, then molts into the next nymph stage.
However, the best strategy to minimize the impact of green semiloopers is to ensure that the crop is well managed agronomically and monitored for the presence of pests on a weekly basis. This is known as integrated pest management. Parasites such as Brachymeria lasus, Charops bicolor and Charops brachypterum can be used to control larva and pupa. Apanteles species can be used as parasites against larva.
Near or upon the larva there is a guard of ants, usually specimens of Formica cinerea Mayr. The larva as well as the chrysalis are found in the nests of this ant. Pupa elongate, green with red dorsal line; abdomen above yellowish green. The butterflies are on the wing in May and again from July onwards, but are said to have only one brood in the north.

Clover leaves united by larva Larva The wingspan is 19–22 mm.Lot Moths and Butterflies Adults are on wing from May to late June and again from July to September in two generations per year.
Inside, the 3 cm tunnel-like chamber contains a larva or pupa. The larva overwinters fully fed in a cocoon, preparing an exit hole before it pupates in April or May. The exit hole is just above a bud and is covered by silk mixed with reddish frass. When the moth emerges the pupal exuviae is left in the exit hole making the gall easier to find.
Mesoderm is formed from mesenchyme originating from the archenteron. The coelom is formed by schizocoely, and the blastopore (a dent in the embryo) becomes the mouth. Photo of an actinotroch larva The slug-like larva of Phoronis ovalis swims for about 4 days, creeps on the sea-bed for 3 to 4 days, then bores into a carbonate floor. Nothing is known about three species.
Similar to other oyster species, once a Pacific oyster larva finds a suitable habitat, it attaches to it permanently using cement secreted from a gland in its foot. After settlement, the larva metamorphoses into a juvenile spat. The growth rate is very rapid in optimum environmental conditions, and market size can be achieved in 18 to 30 months. Unharvested Pacific oysters can live up to 30 years.
Imago, larva and Typha latifolia inflorescence, showing external effects of the larva inside it The moth is about . Adults are on wing in July in western Europe UKmoths and from June to August in North America. Adults have shiny yellowish-tan forewings with two white-ringed dark brown dots and some dark brown shading near the apex. The hindwing is tan shaded with gray.
C. putoria undergoes three larval instar stages. After hatching from the egg, the larva in the first instar is long with 11 spine bands aligned along its 12 separate body segments. In addition, a pair of spiracles can be seen on its most posterior segment with a singular spiracular opening. During the second instar, the larva remains cream-white in color and grows to in length.
In the later stages the larva continues feeding on the leaf-tissue within the blotchy mine. Finally, it leaves only upper and lower epidermal layers of the leaf. Grains of the frass are scattered in the mine cavity, usually along the margin. When fully grown, the larva changes body colour into crimson-red and leaves the mine for a pupating site through a semicircular slit.
The moth flies in July and August. Larva either yellowish with two broad reddish subdorsal lines, or greenish yellow with grey subdorsal and lateral lines; head and thoracic plate black brown. The larva of the coast form, according to Aurivillius, is whitish with the dorsum reddish and small brown head. The larvae overwinter and feed on various grasses, including glaucous sedge and cock's-foot.
Other arthropods may make use of the antlion larva's ability to trap prey. The larva of the Australian horsefly (Scaptia muscula) lives in antlion (for example Myrmeleon pictifrons) pit traps and feeds on the prey caught, and the female chalcid wasp (Lasiochalcidia igiliensis) purposefully allows itself to be trapped so that it can parasitise the antlion larva by ovipositing between its head and thorax.
Red volcano sponge (Acarnus erithacus, Poecilosclerida). Spermatocytes develop from the transformation of choanocytes and oocytes arise from archeocytes. Repeated cleavage of the zygote egg takes place in the mesohyl and forms a parenchymella larva with a mass of larger internal cells surrounded by small, externally flagellated cells. The resulting swimming larva enters a canal of the central cavity and is expelled with the exhalant current.
The larvae feed on Calendula arvensis, Calendula officinalis, Callistephus chinensis, Centaurea cyanus, Dahlia pinnata, Emilia flammea, Erigeron canadensis, Erigeron linifolius, Helichrysum bracteatum and Senecio cruentus. They bore into the flower-bud, flower, terminal end of the stem or the fork of the stem of the host plant. When the larva bores into the stem, it makes a tunnel. The larva pupates within the stem or flower.
Coleophora ibipennella is a moth of the case-bearer family (Coleophoridae). It was first described by Philipp Christoph Zeller in 1849 and is found in Asia, Europe and North Africa. The larva feed within a pistol case on oak leaves (Quercus species) and in the past was confused with Coleophora betulella, whose larva feed from a similar looking pistol case on birch leaves (Betula species).
Once the larvae hatch, typically between 5 and 8 days after the egg is laid, the larva eats its way to the base of the goldenrod bud and induces a gall. These galls serve as food sources and shelters from rain, wind and ice. Despite being the larva's overwintering structure, the gall itself does not provide significant insulation. Instead, the larva itself has robust freezing tolerance.
P. tibialis flies, along with a few other Conopidae species, lay their eggs inside bees and wasps (order: Hymenoptera). The larva has a white and bulging appearance right after it emerges from the egg around one to two days after it is laid. It uses its pointed, extendable mouth to rupture the egg. The larva then goes through 3 instar stages, molting between each stage.
When the egg hatches, the larva eats the paralysed spider, keeping the spider alive as long as possible by eating peripheral flesh first, and saving the vital organs till last. By doing this, the spider stays fresh long enough for the wasp larva to mature and pupate. The pompilid wasp species Tachypompilus ignitus is at least largely a specialist hunter of mature Palystes females.
The damaged florets are joined together near the entrance holes. Often as many as 15 florets are joined together in a row, forming a tunnel in which a fully grown larva may be found. The larva spins a silken cocoon within which it pupates. The pupa is almost white at first, turning brown soon after, and almost black when the adult is ready to emerge.
By the fourth instar, the tarantula's abdomen has collapsed slightly. At the fifth and last instar, the larva has developed a pair of stout, three-toothed mandibles to keep up with its feeding habits. The larva has become muscular and mobile by this stage. It cuts a hole into the tarantula's carapace and thrust its head and thorax inside the host spider, continuing to feed ravenously.
The flight season is recorded in August and October, but also sometimes earlier in the season.. Larva pale tannish-peach colour; dorsal and subdorsal lines white, with darker edges; spiracles black on a pale yellow lateral line; head brown with black markings. The larva feeds on various grasses. # The flight season refers to the British Isles. This may vary in other parts of the range.
The species occurs mainly in August and September, although there are records from June to October.. Larva dull reddish grey; dorsal line white, dark-edged; subdorsal line black, edged beneath with white and then a dark shade; spiracles black on a paler stripe. The larva feeds on various grasses. The species survives winter as a caterpillar. # The flight season refers to the British Isles.
Coleophora ditella is a moth of the family Coleophoridae. It is found from Germany to the Iberian Peninsula, Italy and Bulgaria. Mined leaf of Artemisia campestris with larva-case attached Larva Larval case The larvae feed on Achillea millefolium, Artemisia alba, Artemisia campestris, Artemisia maritima, Artemisia vulgaris, Aster linosyris, Helichrysum and Tanacetum cinerariifolium. They create a tubular, two-valved, black sheath case, somewhat narrowed behind the mouth.
She then grooms for a period. After grooming, she resumes feeding the larva and regurgitates the liquid portions of the morsel into the larval mouth, after which she once again grooms. During regurgitation, most of the contents of the crop may be released, or the female can choose to withhold a significant portion of it. The female thereby simultaneously feeds both the larva and herself during malaxation.
Larva can be hand picked and adults can attracted using pheromones. Regulation of water level in the fields, and removal of alternate hosts from the field are also effective. Among biological controls, ducks are good; they can locate larvae hiding in the soil or at the base of plants easily and prey on them. Introduction of Cotesia ruficrus, and Eupteromalus parnarae also parasitized the larva.
Larvae of trombiculids cause severe pruritus to their hosts after they detach. The larva secretes a proteinaceous feeding tube, the stylostome, into the host's skin. This remains after the larva has completed engorgement on blood and induces an intense localized inflammation. Eutrombicula alfreddugesi and E. splendens are common in the Americas where they infest the skin of the face, muzzle, legs, and belly of cattle and horses.
The larva eats nearly all of the inner tissue of the leaf before moving on to the next leaf. One larva finishes an average of twelve leaves during its two-week larval period. It then pupates for about a week and emerges as an adult. Hydrilla verticillata collection on Lake Seminole, Florida This insect has been shown to be effective in the destruction of hydrilla.
After mating, the female lays an egg in moist ground, which hatches after a short time into a larva that feeds voraciously for 2 to 5 months. When the larva has matured, it pupates for several weeks, and then transforms into an adult beetle. It will live as an adult for several months. Not all larvae survive pupation, many die before molting into pupa form.
The female lays over 300 eggs one by one in the lower leaves and rhizomes of the salvinia plant. The larva is white in color and about 4 millimeters long. It burrows through rhizomes and feeds voraciously on new buds, warping and stunting the plant until it eventually sinks. The larva pupates underwater amongst the rhizomes of the plants in a cocoon it weaves from root hairs.
The parasitoid larva hatches and consumes the interior of the moth larva's body, killing the pest larva. Historically, the most abundant parasitoid has been the braconid wasp Dolichogenidea tasmanica, and it is still the most common natural enemy found with the moth in New Zealand.Varela, L. G., et al. (2010). New Zealand lessons may aid efforts to control light brown apple moth in California.
This species has now been proven to be very similar to those in the families Melanellidae-Entoconchidae, so it is not necessary to allocate it its own family as the taxonomist Thiele did in 1929. However, there are some similarities and some differences. The larva is a typical veliger with smaller lobes like the Melanellidae-Entoconchidae. However this larva has a pericardium and a kidney.
The osmeterium, when everted, is generally yellow to red. While inactive, mainly during daylight hours, the young larva lies along the midrib of the underside of the leaf. Later on, when it is largely fully grown, it is greener and lies on the centre of the upperside of the leaf, on a stem or a twig. The fifth instar larva is about 5 cm long.
Exaeretia allisella is a moth of the family Depressariidae. It is found in most of northern and central Europe, Siberia, the Russian Far East, Mongolia and northern and central China."Exaeretia Stainton, 1849" at Markku Savela's Lepidoptera and Some Other Life Forms A sprig of Lithospermum officinale eaten by larva Larva The wingspan is 20–23 mm.Hants Moths Adults are on wing from July to August.
It is about 6 millimeters long. The female lays glossy, milky white, oval-shaped eggs at the bases of open yellow starthistle flowers. The larva emerges from its egg in a few days and goes inside the flower head, where it feeds on the developing seeds. A larva is capable of destroying all of the seeds inside a given head, with an average reduction of 96%.
When possible, larva will cannibalize the larva of smaller instars. A 1999 study showed that cannibalism only benefits the caterpillar when other food is scarce. Despite this, the caterpillars will cannibalize others whenever they can, even though it was found to decrease their own fitness in many cases. One known reason why cannibalism is detrimental to the fall armyworm is because of disease transmission to the cannibal.
A meconium, or the accumulated wastes from the larva is cast out as the larva transitions to a prepupa. Depending on its species, the parasitoid then may eat its way out of the host or remain in the more or less empty skin. In either case it then generally spins a cocoon and pupates. As adults, parasitoid wasps feed primarily on nectar from flowers.
Samus Aran brings the last Metroid to the Ceres space colony for scientific study. Investigation of the specimen, a larva, reveals that its energy-producing abilities were actually harnessed for the good of civilization. Shortly after leaving, Samus receives a distress call alerting her to return to the colony immediately. She finds the scientists dead, and the Metroid larva stolen by Ridley, leader of the Space Pirates.
A more promising explanation of caste determination involves a pheromone excreted by the current queen. The queen excrete a pheromone to which larvae are sensitive between two and five days after emerging from the egg. The presence of the pheromone forces a larva to enter an irreversible pathway towards development as a worker. The absence of this pheromone causes the larva to become a queen.
The embryo has a small yolk which feeds the larva as it drifts with the tide from a pelagic environment, towards the shallow and sheltered mud/sand flats along the coastline. Because the yolk cannot sustain the larva for very long, adult flounder try to breed in areas that are as close to the coastline as possible, whilst maintaining the right conditions for spawning. This reduces the amount of time that the larva spends feeding itself when drifting with the tides and ensures that the maximum number of offspring reach the inshore waters. After hatching, R. leporina larvae are bilaterally symmetrical and resemble the larvae of other teleost species.
Cotesia urabae is a small (2.5-3.2 mm long) wasp, having a black body with yellow-brown legs, characterized by a solitary larval endoparasitoid stage (Austin and Allen, 1989). It is part of a large complex of 11 primary parasitoids of Uraba lugens Walker, many of which are polyphagous (Allen, 1990a, 1990b). The female inserts its ovipositor into the a U. lugens larva, depositing its eggs there, and it has been found that one female may carry up to 400 eggs (Allen, 1989). While C. urabae females are able to attack the same larva several times; only one single parasitoid completes its development in each larva (Berndt, 2010).
008 In the third larval stage, the tsetse larva leaves the uterus and begins its independent life. The newly independent tsetse larva crawls into the ground, and develops a hard outer shell called the puparial case, in which it completes its morphological transformation into an adult fly. The larval lifestage has a variable duration, generally 20 to 30 days, and the larva must rely on stored resources during this time. The importance of the richness of blood to this development can be seen, since all tsetse development before it emerges from the puparial case as a full adult occurs without feeding, based only on nutritional resources provided by the female parent.
The mine starts as an epidermal corridor, but later becomes a shallow tentiform mine. In the end, the larva lives freely under a folded leaf tip.

A sprig of Veronica chamaedrys with larva cases Larva Adult The wingspan is 8–8.5 mm for males and 7.9–8.6 for females. The wings are red- brown with a metallic glow.
Depressaria albipunctella is a moth of the family Depressariidae. It is found in most of Europe, as well as in Libya."Depressaria Haworth, 1811" at Markku Savela's Lepidoptera and Some Other Life Forms A leaf of Anthriscus sylvestris folded by larva Larva The wingspan is 19–22 mm. Adults are on wing from early August to late November and after hibernating again from March to May in one generation per year.
From there, the larva descends as a stem miner. The whole course of the mine often stains reddish or brown and the frass is hardly visible externally, while the larva are visible as a yellow swelling in the stem. The mine is frequently in the more terminal shoots, and can relatively easily be found because of the staining. Larvae have been found in January, February and early April.
The hinge length tends to correspond to larval body length. The larva lay silk strands along this area, parallel to the cut termini. As the strands contract, the notch creates a pinch and the leaf flap is pulled over the leaflet plane. The pinch then becomes the peak of the roof and the larva begins to make “guy- wires” that attach the edge of the flap to the leaflet surface.

Adults are usually dark brown with a creamy-yellow head and three silver bands across the forewing, although adults of form tarquiniella only have a single silver fascia.
The five life stages for the snake mite are egg, larva, protonymph, deutonymph, and adult. The intermediate stages (larva, protonymph, and deutonymph) must shed at least once to progress into the next stage. The ideal conditions in the environment for the mite to fully develop into a parasite are at temperatures between and a relative humidity of 70%–90%. The life stages can be completed usually in 13 to 19 days.
A single egg is laid on the buds of the food plant in May and June. The newly hatched larva enters the twig near the apex of the bud. At first the frass is ejected but as the larva penetrates the twig the frass packs the tunnel. The gall is a spindle-shaped swelling, which can be difficult to find, on a one- or two-year-old willow shoot.
The cutworm larva of the large yellow underwing (Noctua pronuba) Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.
Paenibacillus larvae is a rod-shaped bacterium, which is visible only under a high power microscope. Larvae up to 3 days old become infected by ingesting spores that are present in their food. Young larvae less than 24 hours old are most susceptible to infection. Spores germinate in the gut of the larva and the vegetative form of the bacteria begins to grow, taking its nourishment from the larva.
A dwarf male is sometimes found attached to the mantle or wall of a female's burrow. The developing larva may omit the nauplius stage but always has a cyprid stage. This has chitinous teeth which are used after the larva has settled to abrade the surface and commence a burrow. Two orders, three families, 11 genera and 63 species are recognized, and many more species probably remain to be identified.
Diapause, also known as hibernation, in European corn borers is induced by temperature and changes in daylight length. At higher temperatures, shorter photoperiods are sufficient to induce diapause. At 13.5 hours of light followed by 10.5 hours of dark, 100% of European corn borer larva entered diapause regardless of temperature with the range of 18 to 29 degrees Celsius. At high temperatures and long photoperiods, fewer larva enter diapause.
Females take repeated small meals of blood to support the development within their abdomen of a single larvae over one period. This will be repeated for as many times as the female is able to survive, depending mostly on availability of hosts. The single larva emerges fully grown from the female, weighing more than the female. Then the larva immediately burrows into dry sandy soil to pupate within a protective puparium.
In specific local subpopulations (studied in Wisconsin, Ohio, and Florida), it was found that giant swallowtail caterpillars do better on their local host plant than on other giant swallowtail host plants. The local host caused the larva to develop faster than other plants that were also edible to the larva. However, this feeding specialization hypothesis has not been tested in the species as a whole beyond these three regions.
Referred to as “orange dogs” by farmers, the larva targets sweet orange (Citrus × sinensis), causing damage to this valuable produce-bearing plant. The larvae are most detrimental to younger trees, which they can more thoroughly defoliate. Outside of farms, the species is valued for its aesthetic appeal in gardens, and larger trees will not be damaged by larva presence. They can also be raised to butterflies successfully at home.
This moth flies at night from August to OctoberThe flight season refers to the British Isles. This may vary in other parts of the range. and will come to light but is more strongly attracted to some flowers and sugary foods. Larva The larva usually feeds on wych elm, with a preference for the flowers and seeds, but has been recorded on other elms, ash, poplar, bird cherry and common osier.
The larvae are moderately sized, ranging from 10 to 14 millimeters long. The larva feeds on dead or necrotic tissue for 3 to 10 days, depending on temperature and the quality of the food. During this period the larva passes through three larval instars. At a temperature of 16 °C, the first larval instar lasts about 53 hours, the second about 42 hours and the third about 98 hours.
The female wood white flies near woodland areas with substantial shrubbery, and lays its eggs on tall food-plants. There are several preferred plants on which L. sinapis have been observed to lay their larva. These include Lotus pedunculatus, Lathyrus pratensis, and Lotus corniculatus. Researchers hypothesize that the height of the plant may influence the number of larva laid there—the taller the plant, the more eggs expected.
The most common host of Nothoaspis reddelli is the insectivorous bat Mormoops megalophylla. A member of the Argasidae family, N. reddelli, has a multi-host life cycle (feeding on two or more hosts), feeding off each host to reach adulthood. After hatching, the instar finds its first host to feed upon and grows into a larva. The larva molts and develops into a nymph, which finds the second host.

Tetrastichus planipennisi parasitize EAB larvae by drilling through the bark and laying eggs on its host. The hatching parasitoid larvae feed and develop on the EAB larva, resulting in its death. Tetrastichus completes at least four generations each year and one EAB larva can produce up to 127 Tetrastichus adults. Tetrastichus planipennisi survive the winter as larvae inside their host or host gallery under the bark of ash trees.
Platerodrilus is a genus of beetles of the family Lycidae. They commonly appear in the literature under the name Duliticola, which is an obsolete junior synonym. The females retain a larval form as adults and are about 40–80 mm in length. The females and larvae have a flattened, dark body with large scales over the head, resembling trilobites, hence the informal names Trilobite beetle, Trilobite larva or "Sumatran Trilobite larva".
The larva has a darker middorsal line with paler dorsolateral and lateral lines. The head of the larva is slightly concave and reddish brown to mottled brown. The pupa of the butterfly is green with greenish-yellow wings, and about long. Pupation occurs either on a low leaf of a host plant or nearby a host plant, and the pupa is suspended with its head downwards by the cremaster.
Predation has not yet been studied for C. ohlone larvae, but tiger beetle larva are hunted by ground- foraging woodpeckers, ants, and wasps. Their most important predators are parasitoid wasp and flies that lay their eggs in the beetle larva. The tiger beetle larvae is then consumed by the wasp or fly larvae, which then emerge from the burrow as adults . C. ohlone is active during the late winter and spring.
This stage is the most vulnerable state of the parasitoid wasp's lifecycle. This is the part of the lifecycle that explains why Z. percontatoria prefers the web-building spiders of the family Theridiidae. The larva will begin influencing the spider to build a web. Scientists hypothesize that the larva is somehow able to increase levels of the hormone that encourages behaviors that the spider would conduct before molting or ecdysis.
The brachiolaria develops from the bipinnaria larva when the latter grows three short arms at the underside of its anterior end. These arms each bear sticky cells at the tip, and they surround an adhesive sucker. The larva soon sinks to the bottom, attaching itself to the substrate, firstly with the tips of the arms, and then with the sucker. Once attached, it begins to metamorphose into the adult form.
The adult starfish develops only from the hind-part of the larva, away from the sucker. It is from this part that the arms of the adult grow, with the larval arms eventually degenerating and disappearing. The digestive system of the larva also degenerates, and is almost entirely rebuilt. A new mouth forming on the left side of the body, which eventually becomes the lower, or oral, surface of the adult.
They mine the leaves of their host plant. The mine is mainly on the upper surface and progresses tortuously, ever widening. When the first instar is about completed an exit hole is cut through the upper epidermis and the larva leaves the inner tissue. When the feeding activities of this stage are finished the larva weaves a tiny circular web over some slight depression on the underside of the leaf.
The female is fertilized at the surface and dives to lay egg masses on aquatic plants, such as watermilfoil. The larva emerges and bores into the stem of the plant, gluing together plant material to create a shelter. It girdles stems as it feeds, which causes significant damage to the plant as stems and leaves die or break off. The larva pupates inside an underwater cocoon filled with air.
Third instars are 11–16 mm, fourth 16–30 mm and fifth instar 30–50 mm. When a late instar larva is startled, it lifts its head and inflates the thorax, revealing the eyespots on the meta-thorax. If disturbed further, it everts red osmeterium from behind the head. Early instar larva tends to use osmeterium right away when disturbed, and osmeterium of the first instar is yellowish.
Larva Habitat in Italy Larva dark brown; dorsal and subdorsal lines pale, lateral lines whitish; a row of pale yellow dark-edged oblique stripes, and a yellow stripe across segment 11.

Row, Peterson and Company, Elmsford, New York. 1961. The female looks very different from the male. It resembles a larva, and though it is free-living and has legs and antennae, it lacks elytra and hind wings. The larva of the odd beetle resembles that of most other Dermestidae, but it lacks a tuft of hair at the posterior end and any long hairs along the dorsal surface.
As paratenic hosts, a number of vertebrates, including humans, and some invertebrates can become infected. Humans are infected, like other paratenic hosts, by ingestion of embryonated T. canis eggs. The disease (toxocariasis) caused by migrating T. canis larvae results in two syndromes: visceral larva migrans and ocular larva migrans. Owing to transmission of the infection from the mother to her puppies, preventive anthelmintic treatment of newborn puppies is strongly recommended.
Although cod feed primarily on adult sprat, sprat tend to prey on the cod eggs and larvae. Cod and related species are plagued by parasites. For example, the cod worm, Lernaeocera branchialis, starts life as a copepod-like larva, a small free-swimming crustacean. The first host used by the larva is a flatfish or lumpsucker, which it captures with grasping hooks at the front of its body.

It is single brooded and generally appears in March in Himachal Pradesh. "The female lays her eggs on the young leaves of Machilus odorattisimus trees, Natural Order Lauraceae, about the end of April. The larva is at first of a reddish colour but very soon turns black and white, and lies on the upper surface of a leaf where it greatly and protectively resembles a bird's droppings." Adult larva: brown with two subdorsal and two lateral rows of fleshy-pointed tubercles, each with a spot of red at its base; anterior, middle and posterior lateral patches of dull ochraceous, the latter two meeting on the dorsum; the rest of the larva spotted with black and red.
The first instar larvae begin life as parasites of leafhoppers in the family Cicadellidae and then move to the nests of meat ants, Iridomyrmex purpureus, where they complete their development by feeding on the ant larvae. Females of this species lay large numbers of eggs near the trails of the ants attending the leafhoppers. The first instar larva spins a pad of silk on the abdomen of the host beneath the wings, with a small sac at the anterior end to protect the larval head. Once the larva leaves the leafhopper, it builds an oval, flat cocoon where it molts into a broad, dorsoventrally flattened larva with a small head that can retract into the prothorax.
