there are many Drosophila of the obscura group at my fruit baits in our courtyard (northwest Germany). But this one seems lighter and more slender. A Scaptomyza (not pallida?)? Only about 2 mm.
Not Scaptomyza , too many rows of acrostichal setae. It might be just a somewhat paler specimen belonging to the obscura-group, but on the base of only this picture its identification would be ambiguos.
