Still another of my Sugar Maple sap feeders. What huge antennae! Some white hairs on the eye, and a white rear end.

The arista seem to be bare from what I can see of them. I am also having trouble seeing the wing venation through the glare.

Well I suppose I am leaning toward Tachinidae. ID help will be appreciated.

Woodlands, West Virginia USA, 11 November 2006. Not sure of size, and I got only one photo (I cropped to get the second image below).
