Hi Helge, I think it's a male Oxycera nigricornis (though I'm slightly confused by the yellow dots on the back).

Greetings, Eric

Interesting observation by Eric. These yellow spots shouldn't be there, according to Rozkosny (1982).
"Mesonotum medially black, at most with small yellow spots on notopleura, transverse suture and postalar calli'

That said, I totally agree with male nigricornis.

@Helge, it would be helpful if you could mention altitude, especially in those cases in which the altitude is above 1000 m. Thanks

Ok, thank you both!
I also wondered about these spots.

Photo was taken by a friend - unfortunately I dont know the altitude, but I will ask him.

Well, in this case it is clearly no pseudoamoena, so altitude is no longer necessary.

Hi Theo,

it was found at just under 1000 metres above sea level (940m a.s.l.).

Why is it no longer important?

It has become clear, it is not a strict alpine species.
In general, especially in aberrant specimens, having all information available like locality, date and altitude might help. If for instance, the altitude is 200 m. asl., I can excllude Glaucops hirsutus for sure.

If you don’t like altitude, your only option is to migrate to the Netherlands Smile
