When I took this picture I assumed it was a wasp. Evan after going to BugGuide.net for identification that’s what I thought. I mean, it has that wasp-waisted look. But I wasn’t able to find any wasps that matched. That’s because it isn’t a wasp, it’s a fly, a thick-headed fly (Family Conopidae) to be precise. I think it is probably Physocephala tibialis, but I’m not completely sure. Anyway, it’s a pretty little thing and I’m pretty happy with this picture, especially as it’s the first thick-headed fly I’ve seen (at least knowingly).
