Found in a little woodland clearing. Josh Rose identified this as an Atomosia
, but after perusing images on the web, it seems to be one of the Laphria canis
complex. See Internet references under guide, and Herschel Raney's comments on Troy's photo:
It has captured a prey item, which I can't make out--perhaps a small dipteran or homopteran with rather long wings. The abdomen is just visible on the robber fly--this looks like a male to me, but I'm not sure.
