Hello Black,
It's a species of Eumerus, but after that it is very difficult to ID it to species from a picture. There are a lot of species in this genus, and especially the females (and this is a female) are difficult to separate!

Ooops, totally right, thank you Jere!
Black, don't mind the name Eumerus, I got confused with indeed Pipizella!
The rest of the comment stays the same, but it could indeed be P. viduata, although for your region there could be more species that look like this!
Greetings
