flight period

I agree with David that this is Andrena cineraria - I've never seen the much rarer A. vaga, but it is supposed to have all-white hairs on the thorax, rather than the white and black pattern of cineraria.

What's surprising though is the date - Andrena cineraria is supposed to fly in April and May! The BWARS atlas account for cineraria does say that "rare records ... from August may represent a second brood", but 28 October is extraordinarily late. Could this one have emerged inside a shed or greenhouse do you think? Have you seen any others? Maybe it's a very rare third brood!

Would be worth reporting to BWARS if you're not already in touch with them, see:

A cineraria

When Andrena cineraria was suggested, I thought it was a rather late date but I didn't think in terms of that late. It was found about 3 metres from a garage, but that has a solid concrete floor. If it was locally reared then I would be a bit surprised - in this area it is an insect more closely associated with well-drained Cotswold soils. I haven't seen any other examples. Record submitted to BWARS - thanks for the link.

A cineraria

In response to my record, the BWARS recorder suggests that the bee was affected by interupted hibernation due to the warm weather we experienced in October.
