Tree Bumble Bee

We have a tree bumble bee nest in the garden, it;s in the shed in an old nest box used by a robin last year. Their fav place to nest.

A busy day rushing here and there and also taking delivery of a new bed. No instructions on how to put it together and there does not seem to be the correct number of bolts. We tried our best but it still looks a bit shooglie. I will need to phone them tomorrow
