Our town park, size 2.5-3mm.
It appears to me rather greyish when compared with reddish and yellowish flies I usually see, so maybe it's different? Probably the picture can reveal some crucial details (to those who know what to see

).

Lonchoptera species are very variable in body colour, so it is best to rely on chaetotaxy to distinguish them. If the middle tibia of this female has an anteroventral, then I'd say this was
furcata. If not, then it's probably
lutea.

Hi Dima.
Can't give you speciec too. Take the sex instead - it is female.

Hi Dima,
According to several keys, the antenna in
Lonchoptera lutea should be completely black (which is not the case in your specimen). I expect this specimen will have an anteroventral bristle on the middle tibiae and that it will be a female of
L. bifurcata (which is the correct name, not
L. furcata).

Many thanks Tony, Nikita, and Jan - I'll try to check that anteroventral bristle on tibia II and inform you then.
