Marlton, Burlington County, New Jersey, USA June 4, 2007 Size: Maybe around 6 mm?
The metalic color makes me think of Longlegged Flies (Dolichopodidae). The wings have very few veins, but they seem to match Diaphorus pretty well. Is that a possibility? http://bugguide.net/node/view/141131/bgimage
Maybe Dolichopus?
Female?
