Eristalis something for ID please

This today, I'm thinking it's not E.tenax, pertinax or horticola, which are the only three I've got shots of here, although Janet was kind enough to ID the E.horticola and I'm not sure what the telling features were, so although this looks different, it might be?! More angles available! Help would be appreciated.

Pertinax

Yes, look at the front and mid tarsus. It is all yellow.

Pertinax is the only one of the Eristalis range of hoverflies which has this.

Other colouration is rather variable, like the similiar species.

Thank you Dogghound and Geoff F! I did look at drawings of wings, and thought it looked a bit like Pertinax, but didn't think the hind femur looked right. It is SO helpful to know about the yellow front and mid tarsus! ATB - Rhona
