Looks like
Hydrophoria lancifer.

Thanks a lot, Stephen. I have changed the title and will wait for confirmation. Maybe it's just me, but I think this one looks a bit different from previous specimens of
H. lancifer that I've seen. Is it a variable species and what are its key features?

Can you see the arista clearly in any of your pictures? It needs to be plumose for
Hydrophoria. Given this, the leg colours and lack of fore-marginal bands on the abdominal tergites would lead to
H. lancifer (or
H. diabata, which is separable only from the genitalia).
Hylemya is ruled out by the hairing of the scutellum and acrostichal region and by the well-developed lower calypter. Nikita's photo at
http://www.dipter...to_id=1761 is not dissimilar to this.
If the arista is not plumose, it's back to the drawing board :)

Arista is plumose, thanks for your help.
