I live in Austria where we are currently approaching winter with temperatures around 5C currently. 2 days ago I found what I identified as a Blue Carpenter Bee, which I understand from my research is an endangered species in Europe. See attached photo.
I found it on our lawn hardly moving, but suspecting that it may only be cold not dying, I brought it inside to warm up. It is definitely alive but I think it was trying to find a hiberation spot.
How can I keep it alive and help it hibernate?
My internet research has not produced any help on this topic.
