Figure 9.

The relationship of the inner pupal case to the thorax of pupae. (A) SEM of the head of a 32-h pupa. The outer pupal case has been removed. As seen here the inner pupal case (IPC) follows closely the contours of the pupal head. (B) Transverse Epon section through the thorax of a 32-h pupa stained with toluidine blue. Note that the IPC tightly encloses the dorsal surface of the thorax. (C) Transverse Epon section through the thorax of a 36-h pupae. Note that this pupa has shrunk leaving considerable space between the IPC and the pupa. Bars, 100 μm.
