Anthophora plumipes is a large, furry black solitary bee with orange hairs on the hind legs that flies in early spring - a much bigger bee than this one.

Many thanks. I think I'd better check other images I'd assumed (perhaps wrongly) to be the male of A plumipes.
Males and females are very different. Females are black, males brownish. http://www.bwars.com/index.php?q=category/taxonomic-hierarchy/bee/apidae...
