Rhamphomyia longicauda - male

Rhamphomyia longicauda - Male
Parkwood, Durham County, North Carolina, USA
May 14, 2005
Size: 10 mm
At my porch light. Length 10 mm, head to wing tips, measured in place. (About 8 mm to tip of abdomen, visible through wings.)

Large eyes indicate this is a male. Compare another photo of a female of what is possibly the same species, at the same location, where the eyes do not meet at the top of the head.



Image updated 2/22/2020! Looking at other images here, I do indeed see the long "tail" (abdomen) through the wings, indicating this is longicauda, according to discussion here:


Moved
Moved from Rhamphomyia.

Dance fly
Actually, this is a dance fly, family Empididae. The darkened wings make it rather difficult to be 100% certain, but I think vein R4+5 is not forked and that would make it a species of Rhamphomyia and I then suspect the subgenus Lundstroemiella.

Neat, thanks
Thanks. I wonder if this might be a male of what appears to be R. longicauda, or a similar species. See thumbnail of a female of this genus in the caption to the photo above.
