Eyes and abdomen

The eyes are hairy, but are not showing the vertical rows of hairs which tenax has. The abdomen pattern is so variable in Eristalis that that shown by this fly would fit for several species, not just tenax. All in all, it is a good fit for pertinax, which is the commonest Eristalis on Ivy where I am, at the moment.
