NEW KIDS ON THE BLOCK
by Peter Hanscomb
We have a new garden resident, or I should say residents. One of our bird boxes has been colonised by what I think are Tree Bumblebees. ( any help with identifying my new friends would be most welcome)
The tree bumblebee is an invasive species here in the U.K. , first spotted back in 2001. So far there has been no significant signs of any aggression from my new friends. And the limited research carried out so far indicates no threat to their native cousins.
