Molting in insects is followed by many physiological processes: the sclerotization of the cuticle or tanning, which entails its hardening and darkening, water loss followed by secretion of the endocuticle, and sometimes its melanization. In the adult whose wings need to remain soft in order to be able to unfold, tanning is preceded by a change in the mechanical properties of the cuticle, called plasticization.
