I see what you mean about the Epistrophe species, but the black tarsi aren't right for them. I did wonder if it might be Parasyrphus nigritarsus, but that doesn't seem quite right either.
We can't see the first pair of yellow spots on the abdomen very well, but they look quite narrow to me, and that plus the dark tarsi leads me back to thinking this is Syrphus, probably Syrphus ribesii.
Does that sound feasible, or were there other reasons for thinking this was Epistrophe?

That's a good call on the dark tarsi. :)
I think I made a bit of a jump to Epistrophe because the yellow bands look so parallel, much more so that the moustachioed bands I'd expect on Syrphus. But looking again there may be more shape to them than I first thought, I think the body angle and position of the wings might make them appear straighter. (This is the only photo I got.)
I can't see any objection to Syrphus ribesii.
Thanks for your help.
