Ready for hibernation

There are still a few bumblebees around in the garden but not for much longer.  In the past week I have seen tree bumblebees (Bombus hypnorum), common carder bees (Bombus pascuorum) and buff-tailed bumblebees (Bombus terrestris), such as this one.

I find bumblebees difficult to photograph.  They are usually head down in the flowers and their black is so black it is a very high contrast with the flowers.  At least at this time of year they don't move as quickly.  This one will soon be asleep until next spring and is already dozy.
