part_of physiological process of malaria vector deposition of the new cuticle hardening and darkening of cuticle IDOMAL:0002166 IDOMAL:0002166 Three hours after larval-pupal ecdysis the epicuticle darkens. The outer seven lamellae of the procuticle which constitute the outer region of exocuticle darken shortly thereafter, and subsequently the epicuticle and outer exocuticle look like a single homogeneous layer. The colour of the pupal abdomen changes from white at ecdysis to grey after one hour and to dark brown after three hours. idomal_namespace
