Photos by Tom Murray: taken in Essex County, Massachusetts, August 31 2012.

Using Manual of Nearctic Diptera Vol 2, I keyed these (from the specimens) to Plesioclythia (1 eastern sp., 3 western spp.). Hopefully that is the correct determination. This genus has apparently been synonymized with Lindneromyia. I don't have the literature to do the scavenger hunt for the name of the eastern species that was once in Plesioclythia (maybe flavicornis Loew ??), but I'm hoping someone here will know! :)

Photos are of two individuals.
