Wild Wednesday - Bees

There were two bees on the white buddleia this afternoon.  I have put one as the main blip and the second as an extra.
I know they are both bumblebees  but have no idea what they are exactly., I am relying on clever people on Blip to know the answer.

Both the purple and the white buddleia have been out for a while now and this is the first time I have seen either a bee or a butterfly anywhere near them.  So 2 bees at once is twice as exciting.

Thank you Cailleach for starting the Wild Wednesday challenge.
