In biology, exuviae are the remains of an exoskeleton and related structures that are left after ecdysozoans (including insects, crustaceans and arachnids) have moulted. The exuviae of an animal can be important to biologists as they can often be used to identify the species of the animal and even its sex.
As studying insects, crustaceans, or arachnids directly is not always possible, and because exuviae can be collected fairly easily, they can play an important part in helping to determine some general aspects of a species overall life cycle such as distribution, sex ratio, production, and proof of breeding in a habitat. Exuviae have been suggested as a gold standard for insect monitoring. For instance, when monitoring dragonfly populations the presence of exuviae of a species demonstrates that the species has completed its full life cycle from egg to adult in a habitat. However, it has also been suggested that the fact that exuviae can be hard to find could lead to an underestimation of insect species compared to, for example, counting adult insects.The Latin word exuviae, meaning things stripped from a body, is found only in the plural. Exuvia is a derived singular form, although this is a neologism, and not attested in texts by Roman authors. A few modern works use the singular noun exuvium (e.g.). Only a single historical work by Propertius uses the singular form exuvium, but in the meaning spoils, booty.

Exuvial refers to something that is related to exuviae, which are the remains of an exoskeleton or skin that has been shed by an animal, typically an arthropod or reptile. In broader symbolism, it can also refer to the process of shedding or discarding old, restrictive structures or attitudes.

In the field of entomology, for example, exuvial fluid is the liquid that hardens to form the new exoskeleton in insects after moulting.

The adjective form is most commonly used in scientific contexts.
