While exploring a wasp’s finer details under extreme magnification I stumbled across some rather mysterious structures:

What are they?

To earn points in tonight’s challenge, be the first person to pick:

  1. The name of the objects (5 points).
  2. The type of insect usually associated with these (2 pts; hint: not a wasp!).
  3. The physiological function (3 points).

The cumulative points winner for the month of February 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!
