Ecdysis, ek′di-sis, n. the act of casting off an integument, as in serpents.
In the higher Lepidoptera the pupa is immovable, and the imago, after the ecdysis of the pupal cuticle, must emerge.
The first ecdysis occurred after 5–6 days, the length of the caterpillars being from nine to ten millimeters.
After the second ecdysis the marking and colouring only undergo change with respect to the eye-spots.
- the periodic shedding of the cuticle in insects and other arthropods or the outer epidermal layer in reptilesSee also ecdysone
C19: New Latin, from Greek ekdusis, from ekduein to strip, from ek- ex- 1 + duein to put on
