My first thought on this one was Drosophilidae, but if the antennae are plumose I can't see it. Any other possibilities?

This is another fly at the Sugar Maple sap. Woodlands, West Virginia, USA, photographed 10 November 2006. Length about 3.5 mm.

ID help appreciated!

Lauxaniidae. In the 'old' day this was Lyciella, but it could well be that this species is not Pseudolyciella.

Ah, Lauxaniidae, that makes sense! Thank-you Paul.

I'm didn't understand what you said about the genus. I did check Nomina Nearctica, and they list no Psuedolyciella and these two Nearctic species in Lyciella:

Lyciella Collin 1948

Lyciella discolor Cresson 1920 (Sapromyza)
Lyciella rorida Fallen 1820 (Sapromyza)

The genus was split...

These pictures are of a species of Poecilolycia - probably P. annulata (Melander). I only suggest it is this species because it is the more common of the two species (P. annulata and P. browni (Curran)) that look identical except for the genitalia.

Cheers,

Thanks, Steve! I have only seen one species of that genus (P. vittata) and that one looks very different.
