TGIF... from outer space?

This week's lucky TGIF winner is the robber fly! This fly was found near Terlingua, Texas… although it looks like it just flew in from outer space.

Not such a far-fetched notion, considering Terlingua is a bonafied ghost town that is within close proximity (in a West Texas kinda way) to the mysterious Marfa Lights!

The robber fly looks quite ferocious, and as a midair hunter of all types of insects, it actually is ferocious.

Adults use their piercing-sucking mouthparts to inject their saliva (a neurotoxin) into their unfortunate prey. The bristles on a robber fly's face help to protect it when an insect tries to defend itself.

Although the long extension on the back end of the robber fly is often mistaken for a stinger, it is actually an ovipositor used when laying eggs.

I have read that the robber fly can inflict a painful bite, but they say that a person has to “handle it improperly” in order to provoke it. I imagine, as is the case with many insects, if you don’t bother them… they won’t bother you. TGIF!!!
