Criorhina

Criorhina asilica is a superb and rather uncommon hoverfly and it is a bit early for it at the moment. In contrast, E. eligans is a very common species of early spring.

Thanks

What got me on the wrong track was the rather orange / brassy colour of the thorax whereas for this E. eligans in the book I used this was shown as black. Only a few species (of which C. asilica was one) had the right sort of colour.

I suspect thorax colour is not really a feature to look at on hovers.
