Anthophora is surely a spring bee, this photo was taken in mid August; too late for Anthophora, unless its a 2nd brood.
No-one said it was A. plumipes. There are 4 others in the genus.
There are 3 species of Anthophora active in the summer. A. furcata is dark with a red tail (clearly not that species). That leaves Anthophora quadrimaculata and A. bimaculata. This could be either but I suspect it is the former.
A small bee proving problematical. I think I'll post a second image of the same bee seen from a different angle - also one of what I had taken to be A plumipes in a different setting earlier in the year.
