Monday Night Mystery

This scanning electron micrograph shows part of an insect:

For 5 Myrmecos points, tell me the name of those large, curved structures in the foreground. For 5 more points explain their function.

The cumulative points winner for the month of August will take home their choice of 1) any 8×10-sized print from my photo galleries, or 2) a guest post here on Myrmecos.

Good luck!

  1. Hamuli, small hooks on the front of the hind wing of Hymenoptera. They grasp the back edge of the front wing so the two wings function as a single une.

  2. They’re probably from a Heterospilus (Braconidae: Doryctinae), since you’ve been taking SEMs of them. A Heterospilus I have in my office also has three hamuli plus two straight setae in front of them.
