I didn't expect to find such a nice fly in November. It was a warm day and the Sugar Maple tree was oozing sap. Several different fly families were represented, feeding on the sap.

When I looked at this fly, I thought, "It looks familiar. What West Virginia flies does this remind me of?" The answer: flies in Lauxaniidae, Drosophilidae, Scathophagidae, and Phoridae.

As I read up on the families, I eliminated Phoridae and Scathophagidae. I am leaning toward Drosophilidae. Can someone help me here?

The arista, by the way, seemed to be plumose but maybe not all the way to the tip.
