This suddenly appeared on a branch about a week ago. I was surprised I hadn’t seen any part of it before – I walk past this tree almost daily. It was a hive of activity, if you’ll pardon the expression. They appear to be bald-faced hornets (Dolichovespula maculata) and it’s a beauty of a nest. We often have wasps hovering about, and bees among the flowers. This was quite a unique sight for me.
