Any thoughts on this one - Hoverfly?

From today, edge of a damp South Devon wood.

My initial thoughts were for a hoverfly species but I can't place it, although there are some elements similar to Leucozona or a strangely marked Meliscaeva auricollis; but what about the backward bars on tergite 2?

Maybe I've got the wrong group altogether but I can't think what else may fit.

Just a couple of distant images from this angle, then it was off and I couldn't follow it.

How about Episyrphus? Have a look at Plate 3, fig 1c in Stubbs and Falk.

Re: Any thoughts on this one - Hoverfly?

Thanks.

I had more or less come to the same conclusion after a bit more thought and reading the Stubbs/Falk description today. I was chiefly considering the grey thorax markings which appear correct for Episyrphus balteatus.

This species can be rather variable and I have seen various dark forms previously but nothing like this example.
