Figure 4
Micrographs of the developing cuticle. (a) shows the yellow pupal skin encasing the imago during pupation, when the cuticle is not yet formed. 3–4 days later (b), the adult cuticle is starting to form and is distinguishable underneath the pupal skin. The formation of trabeculae is evident from the presence of dark invaginations. In (c), the imago has emerged but the cuticle is still not fully expanded. 5 days after ecdysis (d), the cuticle has reached its final conformation. Scale bar: 1 mm.
