Hi, this is Rudy Mancke from USC for NatureNotes.
Daniel lives in the Summerville, South Carolina area and sent me a photograph of a crazy looking thing up by the window in his house: one of the robber flies. You call them robber flies because they're predacious and robbing other insects of their lives.
This particular one is called the hanging thief, because with the front pair of legs, it grips something, and then hangs down and grabs its prey with the four legs that are free in the back. Wow.
I mean, robber flies come in all shapes, sizes and varieties. Many of them mimic bees and wasps, but they're no problem to people at all. And the face on robber flies, no matter which one you see, are really worth magnification.
