Fly - Pyrgota maculipennis

Fly - Pyrgota maculipennis
Greenwood County, South Carolina, USA
April 26, 2005
Size: 11mm, head to wingtips
Some sort of fly perched on the side of my house at night near a light. There were several of these flies in the area, presumably of the same species. I have a photo of another specimen with the wings spread a bit more.

Pyrgota maculipennis (Macquart)
The wing and body patterns of P. maculipennis cannot be distinguished easily from those of Sphecomyiella valida, but the 11 mm length, body proportions, and especially the shape and banded color pattern of the hind tibia give me confidence in this identification. Sphecomyiella valida is usually at least a few mm longer, stouter of body, and with a gradually expanding hind tibia that is not distinctly banded. Pyrgota maculipennis has also gone under the genus names Sphecomyiella and Boreothrinax.

 
Many Thanks!

Pyrgotidae.
I'm pretty sure this is one of the "other" genera in the family Pyrgotidae. The fact that it was attracted to your lights suggests it was looking for May beetles (which the female wasps parasitize). Very nice image!
