Hi,
In April, you can see many moth flies running on the leaves in a deciduous forest along a small stream east of Berlin. The question is: how many species are present? There were males that I think could be Pneumia nubila according to the peculiar hair tuft in the face (however, Gunnar wrote inhttps://diptera.i...d_id=51508 that other Pneumia males could have rather similar hairs, too).
Here is a group of males (sorry, rather blurred) and one with its horn-like hair tuft.
