Fig. 6From: Microarchitecture of the tsetse fly proboscisMicroarchitecture of the hypopharynx tip. SEM images of the distal tip of the hypopharynx showing the complex structure of the finger-like projections. Five different specimens are shown (a-e). The opening of the salivary duct can be seen clearly in d. In e the tip of the hypopharynx is resting on the labium; each lateral flange ends in a broad tip.
