Tree bumblebee

I was sent this picture of an unusual bumblebee by a friend in Pontefract who found them nesting in the roof of his house. I believe that the bees are tree bumblebees (Bombus hypnorum). This species entered the south of Britain only about ten years ago but it has spread up through England and it has reached Scotland. More information is available at treebumblebee.
