Licnodamaeidae is a family of mites; nymphs retain their moulted exuviae until adulthood.

|
The shells or exuviae of these arachnid relatives are common in beach drift in certain areas of the world.
|
|
Members of the family Conchaspididae secrete a waxy scale, in common with other scale insects, but the secreted scale does not include the exuviae.
|
|
Conchaspididae is a small family of scale insects known as false armoured scales because of their resemblance to Diaspididae (but not incorporating exuviae on their body).
|
|
The adults emerge from the exuviae ready to mate. The emergence is also followed closely by fly-fishermen, and is one of the highlights of the spring fishing season.
|
|
Eurypterids are a group of chelicerates that became extinct in the Late Permian. They underwent ecdysis similarly to extant chelicerates, and most fossils are thought to be of exuviae, rather than cadavers.
|
|
The dry, brown shells (exuviae) remain attached to plants and buildings. Throughout most of the range, this species is active from July to September. Emergence and decline dates vary from year to year and from location to location.
|
|
Some are complete but are most probably exuviae as well. Fossils of the actual remains of eurypterids (i.e. their carcasses) are relatively rare. Fossil eurypterids are often deposited in characteristic windrows, probably a result of wave and wind action.

Tillyard described Synthemiopsis gomphomacromioides in 1917 on the basis of both adults and larvae, but his larvae are in fact probably Synthemis tasmanica, a different dragonfly species. Arthropod researcher Günther Theischinger documented the larvae of Synthemiopsis gomphomacromioides while on a holiday trip in 1994 to Tasmania, near Mount Darwin. Despite falling and breaking his ribs at the start of the holiday, Theischinger observed a newly emerged Synthemiopsis gomphomacromioides dragonfly, and finally discovered exuviae (remains from moulting) from a single female and several larvae. At home, however, he reidentified the exuviae and larvae as Archaeosynthemis macrostigma orientalis, another dragonfly from the same group.
|
|
Researchers successfully collected first-instar exuviae and a specimen of a female along the Wilson River, which matches the description from an earlier specimen of a confirmed male Tonyosynthemis ofarrelli, so scientists have concluded that the female specimen collected is that of Tonyosynthemis ofarrelli.

Exuviae of Tibicen plebejus nymph (Cryptotympanini) Annual Cicada, Neotibicen The Cicadinae are a subfamily of cicadas, containing the translucent cicadas. They are robust cicadas and many have gaudy colors, but they generally lack the butterfly-like opaque wing markings found in many species of the related Tibiceninae.
|
|
The third stage is the pupal stage. This is considered the transitional phase between the fourth instar stage and the adult imago C. annularius. This phase typically lasts between a few days and a week. The first notable development is the exuviae, a protective pupal skin.
|
|
The exuviae can remain protruding from the emergence holes for some time. The wingspan is 17–19 mm. Adults have clear wings, which are covered in scales only on the wing veins, the discal area and the wing edges. They have reddish patches at the tips of the forewings.
|
|
Scale insects have a domed, waxy covering which protects the soft-bodied insect below. Armored scales retain the exuviae (shed cuticles) from the first one or two nymphal stages, and sometimes faecal matter and fragments of the host plant, incorporating these into a hard, protective cover. The adult female palm scale has no wings or legs and is somewhat variable in appearance depending on where it is living; if feeding on leaves, the scale cover is circular and convex, and its colour tends to be greyish- white, while on twigs, branches and fruits, the cover is usually brownish and only moderately convex. The exuviae are yellowish-brown and are a noticeable feature near the centre of the scale.
|
|
It is composed of the frass of the insect and often its exuviae, or bits of shed exoskeleton. The beetle may carry the shield on its back or wield it upon its posterior end. The main function of the fecal shield is defense against predators.Bacher, S. and S. Luder. (2005).
|
|
These casings tend to be quite hard, and have been compared to adobe. Most fecal shields are bound with exuviae, the "skins" shed from the insect when it molts. Some shields, such as that of Cassida stigmatica, are entirely frass-free, made only of exuviae.Müller, C. and M. Hilker. (1999).
|
|
Several small (3.5–4.2 mm long) mature larval cases, some with pupal exuviae attached were collected under lichen covered rocks. It is likely that these are the larval cases of E. grayi. These cases are mostly white, speckled with small grains of sand and minute, dark fragments from the rocky substrate.

The procession concluded with men carrying golden bowls and perfumes, and then the statues of the gods carried on litters (fercula), with their attributes (exuviae) transported separately in special chariots or carts (tensae or thensae). The tensae were pulled by boys whose mothers and fathers were still alive.Versnel, Triumphus, pp. 98, 260.

Some of the chansons are akin to the typical French style of the early 16th century—quick, light, and imitative; others are more in line with the Burgundian style of the formes fixes. De Orto also wrote an early setting of Dido's lament, Dulces exuviae, from the Aeneid (iv.651–4), containing extensive chromatic writing.
|
|
The images and exuviae were displayed at the circus, probably on the wooden platform called a pulvinar.Duncan Fishwick, "Prudentius and the Cult of Divus Augustus," Historia 39.4 (1990), p. 481, citing Festus (500 in the edition of Lindsay). The procession started from the Capitolium, and through the clivus Capitolinus came to the Roman Forum.
|
|
They moult after about ten days and begin to lose their eyes, legs and antennae. The adult female appears after the next moult and the scale develops, incorporating the larval exuviae. The development of the male involves three moults. The male nymph is more elongate than the female and the adult male is orange coloured and has wings.

Exuviae The larva is between 24 and 26 mm long. It is light green with light, brown speckles. The round eyes are sideways on the bottom of the head, the abdomen and the tail blunt. The paired side plates on the eleventh segment of the abdomen, the so-called paraproct, is smooth when seen from the side.
|
|
This mud remains on their exuviae, which emerging cicadas leave at the bases or in burnt out hollows of eucalypts. Within a forest, successive broods may emerge in different locations each year. The cicada's body and wings desiccate and harden once free of the exuvia. The adult lifespan of the double drummer is about four or five weeks.
|
|
Marine annelid worms in the family Serpulidae create shells which are tubes made of calcium carbonate cemented onto other surfaces. The shells of sea urchins are called "tests", and the moulted shells of crabs and lobsters are exuviae. While most seashells are external, some cephalopods have internal shells. Seashells have been used by humans for many different purposes throughout history and pre-history.
|
|
During this phase, the olive clearly shows signs of the attack because its appears darker in conjunction with the tunneling. On the surface, a circular hole due to the remaining residual skin becomes apparent. The pupae remain dormant in the hollow below, protected within the exuviae produced by the mature larvae. At maturity, the adult breaks the exuvia and emerges from the pupa.

Adult Rhopalomyia solidaginis fly, emerging from pupal case Process of ecdysis of a cicada. Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa. Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed. The remnants of the old, empty exoskeleton are called exuviae.
|
|
A. ceylonica is semi-social, a group of insects living in a gallery of tunnels, usually an adult female and its nymphal offspring. After shedding its last nymphal skin, the male consumes the exuviae, and then does not feed again. He searches for a mate after which he will not live for long. The nymphs and the adult females are herbivorous.
|
|
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.
|
|
As an adult, Tonyosynthemis ofarrelli is a predator, feeding on smaller dragonflies and larvae. Females lay their eggs along streams. Samples of larvae and exuviae were collected at multiple sites in the 1990s in north- eastern New South Wales, Australia. The sites consisted of the Timbara River near Billyrimba, the Boonoo Boonoo Falls, and at Wild Bull Park along the Wilson River, also nicknamed "The Bluff".

The body of the palm scale is normally dark brown or black and pyramid-shaped, although some species are circular or elliptical. The body is flattened ventrally and is dorsally convex, with the posterior end being constricted with a protruding operculum. The female remains inside the second instar while producing a hardened test. The exuviae then rupture ventrally and disintegrate, often leaving portions behind which become incorporated into the test.

Like C. ovata it had biramous undifferentiated appendages, but it also had only five abdominal somites like W. fieldensis. However, the poor preservation of the P. spinodorsalis specimens, particularly of the appendages on the head, make it difficult to ascertain its taxonomic placement. This difficulty is further compounded by evidence that the fossils of P. spinodorsalis may in fact be moults (exuviae), and not of the actual animal.

Well-preserved Eocene damselfly larvae and exuviae are known from fossils preserved in amber in the Baltic region. Molecular analysis in 2013 confirms that most of the traditional families are monophyletic, but shows that the Amphipterygidae, Megapodagrionidae and Protoneuridae are paraphyletic and will need to be reorganised. The Protoneuridae in particular is shown to be composed of six clades from five families. The result so far is 27 damselfly families, with 7 more likely to be created.

In Florida, the adults emerge at the end of April or in early May, and in South Carolina, in the first half of June. When ready to transform, the nymphs swim to the surface, split their skin, transform into the subimago winged form and fly off, all in the course of ten to twenty seconds. The exuviae (nymphal skin) float away downstream. Their emergence is synchronised and the males emerge first, about one and a half hours before sunrise.

Kulam uses beetles, effigies, poppets, a boiling pot or some other type of representation of the target victim. These are usually "linked" by including bodily exuviae like hair or nail clippings. These are activated by chants, spells, or symbols (sometimes syncretized with Christian or Muslim rituals). The sorcerer then either harms the effigy to cause corresponding harm to the victim, or physically "sends" objects into the victim's body (which can range from insects, stones, to pins).

Diaspididae is the largest family of scale insects with over 2650 described species in around 400 genera. As with all scale insects, the female produces a waxy protective scale beneath which it feeds on its host plant. Diaspidid scales are far more substantial than those of most other families, incorporating the exuviae from the first two nymphal instars and sometimes faecal matter and fragments of the host plant. These can be complex and extremely waterproof structures rather resembling a suit of armor.
|
|
This suggests that they are a highly adaptive species with a high survival rate. This is also consistent with their wide variety of use (as food source, habitat, exuviation process) in host plants, as they are less choosy as compared to other cicada species. Their exuviae (singular exuvia), which are the outer cast-off skin, can be found in large numbers after a rainy season. This due to the fact that the survival of hatching cicada eggs positively correlates to increasing humidity.

While three species of Eurypterus were purportedly discovered in China in 1957, the evidence of them belonging to the genus (or if they were even eurypterids at all) is nonexistent. No other traces of Eurypterus in modern continents from Gondwana are currently known. Eurypterus are very common fossils in their regions of occurrence, millions of specimens are possible in a given area, though access to the rock formations may be difficult. Most fossil eurypterids are the disjointed shed exoskeleton (known as exuviae) of individuals after molting (ecdysis).

Sometimes obtained exploring the basis of aquatic plants with small peak, opening holes to reach insects hidden inside. Aquatic insects, particularly odonatos emerging, are of great importance in the diet of Sergeant thrushes that breed in swamps. These birds typically capture the odonates when the larvae climb up the stem of a plant from the water, get rid of their exuviae, and cling to the vegetation while their exoskeletons harden. The years of emergence of Periodical cicadas, it provides an overabundant amount of food.

Exuviae from a molt may seem like ghost insects. Russell R. Kirt Prairie, Illinois This large milkweed bug is a hemimetabolous insect, meaning it grows in stages called instars and goes through incomplete metamorphosis exhibiting small changes throughout development such as coloration changes, development of wings and genitalia. O. fasciatus begins as an egg and experiences four nymphal stages over 28–30 days before moulting to adulthood.Leslie, J.F., (1990) Geographical and genetic structure of life history variation in milkweed bugs (Hemiptera:Lygaeidae: Oncopeltus). Evolution 44(2):295-304.

P. schultzi exuviae (discarded "skins") have been found both in their own webs and in those of I. karschi, which has suggested that P. schultzi moults in the open. In one case, while its new skin was still pale and soft, its spinnerets were still stuck in the discarded skin, and the spider slowly twirled for about 90 seconds until it was free. The spider's body then darkened quickly to the normal colouration, and some time later the spider hung in its usual upside-down posture in the web.
|
|
The larval stage is divided into four instars, as observed through the moulting stages. At the end of each moult, a piece of unknown material is seen connected to the exuviae if they are isolated from the workers. The larval stage lasts between six and 12 days before their bodies expand significantly and become pupae; the pupal stage lasts between nine and 16 days. Lifecycle of the red imported fire ant, including several larval instars As soon as the first individuals reach the pupal stage, the queen ceases egg production until the first workers mature.

Domestic and sylvatic species can carry the Chagas parasite to humans and wild mammals; birds are immune to the parasite. T. cruzi transmission is carried mainly from human to human by domestic kissing bugs; from the vertebrate to the bug by blood, and from the bug to the vertebrate by the insect's feces, and not by its saliva as occurs in most bloodsucking arthropod vectors such as malaria mosquitoes. Triatomine infestation especially affects older dwellings. One can recognize the presence of triatomines in a house by its feces, exuviae, eggs, and adults.
|
|
This secondary transmission occurs through direct contact with, or ingestion of, traces of baits dispersed in the environment by contaminated cockroaches. These traces were either deposited by “trampling” in the environment or on dead contaminated cockroaches. The cascading effect goes on to wipe out whole colonies from indirect exposure by contact with the corpses, feces, or harborages of cockroaches previously exposed. Such nests, when contaminated with sufficient residual pesticide via faeces, secretions, exuviae, or corpses provide an important reservoir of pesticide, which would be available to infect co species.
|
|
After mating, females return to their burrows or dig a new burrow and deposit eggs. Excavations of adult emergence burrows revealed pupal exuviae (casings) at depths ranging from approximately 4 to 6 in (10 to 16 cm). The larval cycle for the species is likely one year, based on the absence of larvae (grubs) in burrows during the adult flight season. The food source for Casey's June beetle larvae while underground is unknown, but other species of June beetle are known to eat "plant roots or plant detritus and associated decay organisms".

Display courts are located immediately adjacent to bowers and are decorated with leaves, flowers, fruits, seed pods, insect frass and exuviae, shells, eggshells, bones, stones and charcoal. Man-made objects are also frequently used to decorate bower sites including glass, wire, foil and other metal objects. The number and types of decorations are linked to the mating success of males, suggesting that decorations also play a role in mate choice by females. The types of decorations preferred by spotted bowerbirds varies geographically, which may indicate that females prefer males who collect varying items, depending on their location.

The crawlers are tiny and disperse on the host, each one looking for a suitable protected site with thin bark in which to settle, remaining in that place permanently after sinking the stylet into the host plant's vascular tissues.Colorado State University Cooperative Extension Fact Sheet The crawler moults twice before becoming an adult female, forming a protective scale from larval exuviae and secretions. Some crawlers may develop into males. These undergo four moults and the adult males have eyes, three pairs of legs, one pair of wings, a head and a body divided into a thorax and abdomen.

The discarded, dried exoskeleton typically remains hanging where it was abandoned once the spider has left. To open the old exoskeleton, the spider generally contracts its abdomen (opisthosoma) to supply enough fluid to pump into the prosoma with sufficient pressure to crack it open along its lines of weakness. The carapace lifts off from the front, like a helmet, as its surrounding skin ruptures, but it remains attached at the back. Now the spider works its limbs free and typically winds up dangling by a new thread of silk attached to its own exuviae, which in turn hang from the original silk attachment.
|
|
Once the new cuticle has formed sufficiently, the animal splits the remaining parts of the old integument along built-in lines of weakness and sheds them in the visible process of ecdysis, generally shedding and discarding the epicuticle and the reduced exocuticle, though some species carry them along for camouflage or protection. The shed portions are called the exuviae. The animal then expands its body by swallowing liquid or gas and in the process it stretches the new integument to its proper size and shape. The new integument still is soft and usually is pale, and it is said to be teneral or callow.

These sink to the bottom and hatch after 45 days, the nymphs burrowing their way into the sediment where they spend two or three years before hatching into subimagos. When ready to emerge, several different strategies are used. In some species, the transformation of the nymph occurs underwater and the subimago swims to the surface and launches itself into the air. In other species, the nymph rises to the surface, bursts out of its skin, remains quiescent for a minute or two resting on the exuviae (cast skin) and then flies upwards, and in some, the nymph climbs out of the water before transforming.

The discarded exoskeleton (exuviae) of dragonfly nymph Exoskeleton of cicada attached to a Tridax procumbens An exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton") is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells". Examples of animals with exoskeletons include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters, as well as the shells of certain sponges and the various groups of shelled molluscs, including those of snails, clams, tusk shells, chitons and nautilus. Some animals, such as the tortoise, have both an endoskeleton and an exoskeleton.

The tracks progress and evolve, attaining different characteristics as time passes. The mysterious tones of 'Aluvial,' the hypnotic sound of 'Husk,' the pitch black darkness of 'Breccia,' the peaceful moments of 'Exuviae' and the melodic interludes of 'Calyx' and 'Maar' are just some of the elements that Daniel Menche & Mamiffer awaken through the seventy minutes of Crater." Pitchfork ranked the album at number 12 on its "The Best Experimental Albums of 2015" list. In his description of the album, Pitchfork staff writer Grayson Haver Currin wrote: "[Daniel Menche's] pace has slowed during the last few years, but his new collaboration with Faith Coloccia and Aaron Turner, or Mamiffer, makes up for the lost time.

Most Pentecopterus specimens would have had a total length of . The large amount of fragmentary specimens recovered of Pentecopterus, including juveniles and exuviae specimens, have allowed an almost complete description of the external morphology. Pentecopterus is diagnosed as a megalograptid retaining a single pair of spines on the third podomere of the third prosomal appendages, a short appendage V with a serrated distal margin of podomeres; prosomal ventral plates widening anteriorly, posterolateral pretelson lacking expansion and xiphos-like shaped telson, with a margin laterally ornamented with scales. The prosomal ventral plate is of Erieopterus-type, that is, it consists of a single plate that covers the anterior and lateral portion of the ventral carapace.

The exuviae are usually found on barks of trees and the position or height above the ground is influenced by the size of the nymphs. It is suggested that nymphs with a larger body size have better water content thus allowing them to climb higher and longer with the advantage of reduced transpiration due to their smaller surface area to volume ratio. The adult species are actively found in April to September, where males will sing to attract the females around their area. The male singing sounds like a chorus, starting with one male then followed by the males in the nearby area, and the song will finish at the same time.

Due to the existence of an excellently preserved deposit in the Frankfurt Shale near Rome, New York State, that suggests an entire population of Triarthrus eatoni was killed and quickly buried, it has been possible to make a plausible reconstruction of its life history. After hatching, probably from eggs a few tenths of a millimeter (although these are not known in any trilobite), the small protaspid and early meraspid stages supposedly lived between the plankton in the water column. This is derived from the fact that only exuviae of the early stages were found, making clear that they haven't died in the disaster that killed their elders. In this phase the larvae probably got dispersed over large areas.

In volume 2 of Ornithological Biography (1834), Audubon told a story from his childhood, 30 years after the events reportedly took place, that has since garnered him the label of "first bird bander in America". The story has since been exposed as likely apocryphal. In the spring of 1804, according to the story, Audubon discovered a nest of the "Pewee Flycatcher", now known as Eastern Phoebe (Sayornis phoebe), in a small grotto on the property of Mill Grove. To determine whether the other phoebes on the property were "descended from the same stock", Audubon (1834:126) claimed that he tied silver threads to the legs of five nestlings: > I took the whole family out, and blew off the exuviae of the feathers from > the nest.

However, this north-south pattern does not exist in the Yucatán Peninsula, the southernmost population of the species, where some subpopulations are intermediate between the Delaware Bay and Florida horseshoe crabs, and others are smaller, averaging about the size of Florida horseshoe crabs. Horseshoe crabs possess the rare ability to regrow lost limbs, in a manner similar to sea stars. A wide range of marine species become attached to the carapace, including algae, flat worms, mollusks, barnacles, and bryozoans, and horseshoe crabs have been described as 'walking museums' due to the number of organisms they can support. In areas where Limulus is common, the shells, exoskeletons or exuviae (molted shells) of horseshoe crabs frequently wash up on beaches, either as whole shells, or as disarticulated pieces.
