Exuvia
From Wikipedia, the free encyclopedia
Exuvia (alternative spelling exuvium, plural: exuviae[1][2]) is a term used in biology to describe the remains of an exoskeleton that is left after an arthropod (insect, crustacean or arachnid) has moulted. The exuvia of an animal can be important to biologists as it can often be used identify the species of the animal and even its sex.
As it is not always practical to study insects, crustaceans or arachnids directly and because exuviae can be collected fairly easily, exuviae 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.
