In a chance conversation it was my friend Tony who said he had a couple of Tree bee nests in his garden. When I expressed an interest I even got a cup of coffee and a pair of step ladders to get closer to them thrown in.
Not found in Norfolk until 2008 Tree Bumblebees are quite a distinctive bee and there was a constant stream of them entering and leaving the loft and an air brick but by far the best place to see them was as they fed on a Snowberry at the top of the garden. Thanks to Tony for the opportunity to photograph them.
