ec·dy·sis

(ek'di-sis),
Desquamation, sloughing, or molting as a necessary phenomenon to permit growth in arthropods and skin renewal in amphibians and reptiles.
[G. ekdysis, shedding]

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.

oreganus in the Okanagan Valley of southern British Columbia overlap the period of ecdysis in late summer; males often court and mate within 48 h following ecdysis (Macartney and Gregory 1988).
Another effect observed was that some larvae died due to treatments with higher concentrations (500, 1000 and 5000 mg [kg.sup.-1]) during ecdysis and failed to release the old endocuticle (Figure 3A), thus indicating that the extract caused a disturbance in the endocrine system of the larvae, thereby preventing completion of morphogenesis.

Thermoregulation facilitates quicker digestion of meals, decreases gestation time of gravid females, and is critical during ecdysis. Therefore, thermoregulation might be the most important factor in determining squamate habitat use patterns (Grant 1990, Peterson et al.

The presence of exuviae, mortality and date of imago emergence were recorded daily at the same hour of the day to estimate the development time and survival of each immature stage (ecdysis to ecdysis).
Shedding completed in a healthy reptile is referred to as ecdysis. Failure to shed completely can cause problems.
The novel's title, "The Skin Beneath," refers to the "Ecdysis Conspiracy" (possibly named by Chloe herself), which in turn refers to the natural process by which snakes shed their outer skins to reveal new skin beneath.
There was suppression of ecdysis and 100% mortality of Cotesia congregata, hymenopteran parasitoid of Manduca sexta.
