Bumblebee- Buff-tailed

Thanks for your comments any idea what the difference is between white-tailed and northern white-tailed Bombus magnus

Bombus magnus

The books suggest that, as described by Urophora, the wider yellow collar, extending further down the sides of the thorax, is the main feature separating B. magnus from B. lucorum. Would you say this is sufficiently reliable to confirm it as magnus, Urophora?

Was large enough to be a queen, or just a worker?

The other two species never

The other two species never have a collar remotely like this one. It works in females only, and generally only queens should be identified. This picture is unequivocal, whether queen or worker.

Thanks for your comments I am slightly confused though not being an expert which species is it- remember it was taken in Wales

Bombus magnus

We seem to have reached agreement that urophora's identification of Bombus magnus is the correct one. This species is not included in some of the bumblebee books as it has sometimes been considered to be just a form of Bombus lucorum, but the latest accounts from BWARS say that it is a separate species.
