ecdysis

(ĕk′dĭ-sĭs)
n. pl. ecdy·ses (-sēz′)
The shedding of an outer integument or layer of skin, as by insects, crustaceans, and snakes; molting.

ecdysis

The shedding of the outer layer of the skin. The term is usually applied to the common process occurring during the development of various insects, such as Ophidia and many of the Arthropoda, but is sometimes used as a synonym for EXFOLIATION in humans.

ecdysis

the process of moulting the cuticle in insects, usually in the preadult stage. The old cuticle is split and cast off to reveal a new, soft cuticle underneath; the insect increases in size, often by intake of air, and the new cuticle hardens. Each larval stage is referred to as an INSTAR, so that the first instar is terminated by the first ecdysis, the second instar by the second ecdysis. Ecdysis is initiated by the MOULTING HORMONE.
