Hi,
This small fly was busy on ivy in Berlin on 8th October. I think it could be
Hydrellia maura or
H. griseola, but I don't know how to tell them apart. Help is appreciated!
Thanks, Sundew

Brown dusting extends onto the notopleuron, so that suggests this is
H. albiceps (=
H. maura)

Ah -
H. maura has become a synonym, good to know. Many thanks for the enlightenment!
