Frit Fly (Chloropidae) - Elachiptera

Frit Fly (Chloropidae) - Elachiptera
Springfield, Fairfax County, Virginia, USA
April 15, 2005
Size: 2-3mm
This tiny fly was actually extracted from a spider's web, and it was still moving (though barely) when the picture was taken. I posed the wing to get a better shot for identification.

Based on the wing veins, I'm guessing this is a frit fly, family Chloropidae. The Costa is broken near the end of R1 and the wing lacks the anal cell, which matches the description and diagram given in Borror & White (1). Furthermore, the ocellar triangle, while not visible in the picture, was large and shiny.

But as I'm not very familiar with these tiny flies, confirmation or other opinions are appreciated.

Yes!! :-))
Hello Richard,
You're right, this is indeed Chloropidae

Even better...
..., it is the genus Elachiptera, which is clear from the broadened arista.
