This rather large fellow landed on my front doorframe earlier today! It's very docile and has been sitting underneath the lock for (from the time of this post) 8 hours now. It's moved very little, even with people going in and out. Can anyone identify what sort of bee it is?
EDIT: Not letting me post pictures, please see attachments.
If the bee is still there in the morning, what should I do about it? Leave it be (no pun intended) or move it somewhere else?
I would guess it's a queen Bombus terrestris, born this year and looking for somewhere to hibernate. Ideally you should find it an old mousehole in the ground but, failing that, somewhere where there is a lot of leaf litter it can hide under and be protected from frost.
Yes, I would lean towards B. terrestris, buff-tailed bumblebee.
The other possibility is B. lucorum, white-tailed bumblebee
With both species, October is the the latest they are on the wing. So here in November, the odd individual found is likely to be a queen looking for hibernating quarters or perhaps a male on its last legs (I'm unsure how long the males hang-on).
