Although yesterday’s mystery looked like a mutant cross between a toothbrush and a barrette, it was actually the fore tarsi of this gal:
At first glance the insect looked like a Formica ant worker. The color, texture, shape, and size are about right for Formica pallidefulva. On realizing what it was, though, I went running for my camera. Dryinids are amazing creatures. The crazy raptorial forelegs help females trap leafhoppers into which they inject their eggs.
I’ll give Morgan Jackson three points for picking the structure, and Keith Bayless the full ten points for not only pegging the structure and family but going beyond the initial question to answer the genus and function.
