Black, Red-Eyed Fly? - Rhamphomyia longicauda - Male
Monroe County, Pennsylvania, USA
June 7, 2011
Size: 15 mm
I found one of these in the bedroom the night before, and disposed of it at my girlfriend's request. Sure enough, the next night another one showed up. I had the hardest time identifying it, so I wanted to hopefully have someone let me know what it is. As a note, it's early June in Eastern Pennsylvania indoors that I found this little bugger.

Moved from Dance Flies.

long-tailed dance fly
This is R. longicauda (male)

Moved from ID Request.

Could be Rhamphomyia, a "dance fly". They are predatory on other flies and would not be expected to breed indoors.

Edit: But that genus normally has a long beak.

Thank you for the ID. That is definitely the fly. I wasn't 100% it was the same bug from the night before, but an internet search confirmed it, as I had seen a female earlier - given away by the dark, hairy legs - and a this one was a male.
