Some bees have set up home in a bird box at Mum's house...
Only problem is that the box is on a south facing wall, and gets extremely hot on sunny days. So the bees take it in turns to go and sit by the hole and fan cool air in with their wings. I really love them. As it gets hotter and hotter more and more bees come out to help with fanning duty. (I stole the next two photos of mums facebook, they're taken with her phone, but give you an idea of the busyness!)
They are very loud! After some internet research we think they are tree bumblebees.
Do you have any interesting summer visitors in your garden?
