Taeniaptera trivittata - Female
Hill Forest, trail along Flat River, Durham County, North Carolina, USA
July 8, 2005
Size: circa 10 mm
This was perched on some vegetation in a shady woodland. It was quite tame, and showed us several poses with its forelegs, one up (here), or two up (linked photo below). I believe that is an ovipositor projecting beneath the abdomen--a female. Some other images in the guide show this as well.

Compare flies seen by Troy Bartlett and Bill Dupree, among others:

Thanks to Herschel Raney (comments) for the identification.

You can see in this shot the row of bristles on the posterior tibia. This is an important character. It is present on the big Micropeza genus which has a very different head shape than this species. And it is present on the Taeniapterinae. I think the only Micropezid species in the US with the white semicircle of white on the dark wings (which is visible here) is Taeniaptera trivittata.
