there were lots of these tiny flies near the lamp last night, they are kind of Drosophila-sized I guess and tended to run rather than fly away from me.

I'm guessing all 3 are the same species....

This is as close as I could get as they move so fast!

Not a Syrphid.

I have some photos of flies just like the 3rd one but I have not yet managed to ID them properly. I thought they might be Lonchopteridae but that was just a guess.

And I guess Opomyzidae!? ;)

Thanks Sara-Opomyza germinationis was one of the matches I saw in the book but the colour is different. I guess there are a few different species in that family?

They all look like Drosophilidae. Bottom one looks like Scaptomyza pallida or graminum but I think your images are too small to make anything of...have you tried cropping closer Larry :|.

Too blurry to crop any tighter Roger. I was shooting in near dark and they move quick up this close

Apparently only two rows of acrostichal setae on a darker median strip so probably Scaptomyza pallida.

Thanks Paul. now I hate to sound stupid, I know that setae are fine hairs but acrostichal?
