Key to the Syrphus of Europe

Syrphus is the type Genus of the Hoverflies. It is literally typical. But identification in this genus from photographs is hard, and often impossible. Information on the rarer species is also difficult to find. Here is my best effort at a key to this group that is optimised for photographs. Comments and corrections are especially welcome given that it's such a tricky group.

The species covered are admirandus, attenuatus, auberti, nitidifrons, ribesii, sexmaculatus, stackelbergi, torvus and vitripennis.
