compared to the hanging thieves I'm used to, this one was small.

Okay
This one tortured me. Rests like a Lasiopogon (which it is not). Wings like a Dioctria (which it is not), antenna which eliminates large swaths of Washington species and genera. I have decided it must be a Coleomyia. I have never seen one. Male wings are sometimes bicolored as in this species. Otherwise there are only eight species on the planet and five of them reside in Washington state. One, C. raineri, is endemic to only Wash state. One ranges down to NM. The others are all limited to WA OR ID UT BC and MT and two to CA. Dr. Cannings has seen C hinei in BC. I will have him take a look.

And, by the way, there are no Diogmites (Hanging Flies) at all once you get out to WA.

Dr. Fisher verifies that this is a Coleomyia species. I doubt there are many images anywhere of this genus.
