Efferia [Pogonioefferia] pogonias - Efferia pogonias
Snowhill Road north of Cabin Branch Creek, Durham County, North Carolina, USA
July 26, 2006
Size: 24 mm
One of the Efferia group, see comments for ID. I measured the plant upon which it was perched (29 mm across) to give a good estimate of the length of the fly--24 mm.
