It might be Syrphus torvus. Look on the eyes: if they have hairs, than it is indeed torvus; if it is bare - vitripennis |

The colour of the hind tarsi is no good character to distinguish between ribesii and torvus. The only reliable charcater for the males is the pilosity on the eyes (torvus hairy, ribesii bare or nearly so). The major difference between torvus + ribesii and vitripennis is that the latter has the 2nd basal wing cell partly bare of microtrichia whereas the others have the wings entirely covered by microtrichia.
