Looks like Meiosimyza, the most common autumn species is Meiosimyza rorida.
To be sure - collect and find short av spines at apex of f1.

sorry to put so manny question but i promis that i put only one time the same question :d

av - anteroventral
f femora, t tibia, t3 hind tibia, f1 fore femora.
If you look at your mind at fly from dorsal side and put (also at your mind) all legs at 90 angle to body aside - than low directed setae will be ventral, ahead - anterior, half v - half a will be av (as south-west, for example, in geography)

thanks for explain this to me.
(and i presume that a = anterior and v = ventral :) )

i will check when i will reach my office.
and try to make a photo thru microscope to be sure (for confirmation).

cosmln
