Hi,
is it possible to identify this fly? Mydaea?

I think it could be a male Helina sexmaculata - tricky from only one dorsal photo.
Greetings, Eric

Hi Eric,
thank you very much for answer. Unfortunately, the fly got impatient and flew away after the first picture.
I compared my photo with the pictures in the gallery and internet. In my opinion the distance between eyes of my fly is shorter, but I don't know if that's relevant for the determination.
Greetings,
Marion

Maybe Phaonia tuguriorum.
Best wishes, Niels-Jan Dek

Helina has bare eyes, doesn't it?

Thank you very much Nils-Jan and James.
I attach a cropped section of the mirrored full-resolution image. The eyes are hairy.

Helina sp. do not have naked eyes per se: e.g. H. evecta: "eyes densely haired in both sexes" from Gregor, Rozkošný, Barták, Vaňhara (2016): Manual CE Muscidae
On P. tuguriorum: are the basal segments of the antenna reddish yellow?
And a black mid-line between the fronto-orbital plates should be visible.

Greetings, Eric

I would say they are reddish.

Probably not.
