Hi,
In July I came across this
Coenosia (right?) in a small town in southern Brandenburg. Is it possibly
C. tigrina? And what can the black swelling above the antennae be?
Thanks for help, Sundew

It must be a ptilinum.

Ah - you think the ptilinum remained partly inflated here and did not fully collapse back inside the head. So it is not a dangerous problem to the fly, neither tumour nor parasite. Good to know!

Can we get sloser to the species?

Yes, this must be Coenosia tigrina.
