Dead wood?

Was the nest site in dead wood? The pictures you have here could be of male Anthophora furcata which would explain seeing it later in the year than Anthophora plumipes. The yellow on the face is no where near as extensive as the photos I have seen of male Anthophora plumipes but I don't know if that is a reliable identification feature. See: http://www.bwars.com/index.php?q=bee/apidae/anthophora-furcata

no the nest site was in dry

no the nest site was in dry clay soil under the overhang of a nearby residential building. there were at least 130 occupied nest burrows. The all black female plumipes were regularly seen coming and going. The colony has not been active for several weeks now and all the adult plumipes seemed to have vanished. I thought it was unusual to see the males this late in the year, its been over a month since I last saw any females now either.

Having looked at BWARS I think your right this is Anthophora furcata. The facial markings are not right for plumipes.

Thanks for pointing this out

No problem

No problem Mark.

Without the females there would be little point in the males still being alive, their only real function is to stay alive long enough to mate. If the colony has been devoid of activity for several weeks then it stands to reason that this is a different species. There are 5 species of Anthophora listed in Britain on the BWARS website but one (Anthophora retusa) is very localised to the south coast.

Cheers, John

Is the second photo definately the same bee? It looks different.

im not actually sure, the dam

im not actually sure, the dam thing was flighty and hard to photograph. I may have accidently took a picture of a second bee on the same knapweed plant as I was following it with the camera
