Hallo Ingrid, I'm sure it is Epistrophe but the breathing tubes (posterior respiratory process = prp) look quite unusal to me. It may help if you have pictures with a different view.

Thank you very much Eric!
I have only this photo of the prp. I think they look a little shorter than that on your pictures. but I could of course be mistaken.

Hi Ingrid, on the first image the prp looks like being as long as it should but is bowed down.
I'm working with Rotheray's Colour Guide to Hoverfly Larvae and it says:
"...Prp up to 3x as long as broad, pale in colour with dorsal spurs..."
"...The flattened shape and green colouration make larvae of this genus very distinctive. Seaeva larvae can be green with a pale stripe but they are sub-cyclindrical in cross-section."
I am convinced it is Epistrophe!
