OK, here's the dorsal view. I think you're very close, spiritualspatula. But the markings on the back aren't quite the same, and there's definitely a yellowish tinge to the stripes on the back.

Note: in typical crazy mode, I had my tripod with my D200 and 180mm macro lens on my dining room table, pointed straight up. I had to get up on a stool and lean out over the table to aim and focus.


I agree. Mind if I forward the photos on somewhere else? I'd post them in a forum.


Please do!


Per the master fly guy Paul Beuk over at diptera.info.....
"It is a species of the Drosophilidae, the Drosophila repleta group. They all have a mottled mesonotum."
So I guess I was a ways off on my guess. :\ (although I considered them earlier I incorrectly dismissed them.)
The accurate common name for them is vinegar fly, though most people call them fruit flies (which they aren't). Fruit flies don't eat decaying matter.
Here's some info on vinegar flies.
I should've known what these were. Geez. :(

Happy 1,000 post to me :)
Anyway, empty the trash and make sure there's no food hiding around.

ugly little suckers, aren't they? I'm in Virginia, and I think I'll keep my door closed from now on! (I had it open for 4.5 hours the other day, waiting for the right shot.)

Thanks a million! We assumed they were fruit flies from the start, but then when I squished one, there was a blood smear like we get from killing mosquitoes. That made me wonder what they were biting.

Do fruit flies have red blood? If not, what explains the blood when I squish one?

I think it is a politician fly. You say it is smaller than normal...

This would indicate a smaller brain, and being a blood sucker, it about has to be a politician fly.

They appear to be found in almost every locality around the world.

I'm not sure off hand what color their insides are and I don't have any at the ready to smash, but there's a good chance it would be effected by what they were feeding on.
