Recent I read an article about a new species of bumblebee to the UK – called the ‘tree bumblebee’. It first appeared in the UK (from continental Europe) in 2001 and has spread fast across our islands so that it is now widely distributed. In an interesting example of how knowledge opens your eyes I’ve now noticed a colony of such bees at the school farm.
They are living in one of our nest boxes (apparently one characteristic of these bees is that they like nest boxes) and are both numerous and active bumblebees (again, what they are said to be like). I think it’s quite likely that without first knowing about these bees I would have overlooked them.
