Hard to tell from this angle. At least no quadrimaculata, because their males don't have spots on the tergites.

Hi Andre,
hi Gerard,

so for me: Melangyna sp. (quadrimaculata/barbifrons)
Thank you for your help.
Regards Pia

Hello Pia,
Well, from picture 1 it?s clearly visible that it has densely haired eyes, and picture 3 shows a black face.
Males of Melangyna barbifrons have virtually bare eyes and a black face with yellow patches, so this is clearly a male Melangyna quadrimaculata!
Greetings

Hi Gerard,

thanks a lot for your explanation.
It's really Melangyna quadrimaculata. I'm enjoy.
Greetings Pia
