Moved
Moved from Allohelea. Mesonotum definitely dark brown with irregular, pruinose gray areas... actually you can see that in the above image. Assuming the dististyles are the terminal appendages, those seem to match this species better too. Wing length seemed intermediate, 1.4 mm or so.

Wing length
The Wirth convention measures wing length from basal crossvein to wingtip, not from true base of wing to wingtip.

The dististyle is the part that is folded in in this picture of the related family Chironomidae:

Moved
Moved from Flies. Two New England species, distinguishable by exact size (wing length) or other characters mentioned in the revision on the genus page. This is a male (fuzzy antennae). One species was reared from fungus, though the tribe is predatory.

Biting midge?
Wing suggests Ceratopogonidae.
