I saw this bug in my garage last Thursday. I thought that it was a wasp or a mosquito when it landed next to me, but it did not behave like one, and it was entirely passive for as long as I was around it. Any idea what it is? I live in the middle section of the east coast of the USA.This looks like one of the Hanging Thief Robber Flies (Diogmites sp.), a genus of robber flies which hang while feeding. Not to be confused with Hangingflies which are in a completely different order and are more closely related to scorpionflies
