I photographed this fly at Sugar Maple sap in the woods, but then photographed another one half a kilometer away in an open area.
Sepsidae? Can anyone provide further information on this fly?
West Virginia USA, 14 March 2007. Size: 3.5 mm.

A female of the genus Sepsis? By the way, how do we determine that this is a female from the photo?
Thanks, Nikita and Black for replying.

First image with fatty abdomen looks female, the second one looks male - abdomen thiner and it seems that there are weapon (spines, strong setas) on ventral surface of f1.
