These are a collection of pictures of some of the swarms that were collected last year.
Some times swarms are small as this one collected from a hedge in Surbiton
Unusual to get one this size though and on the ground. Something to do with the rain that was pouring down at the time. The school was grateful to have it removed as it was alongside the path where parents collected the children. It was approximately a metre across.
Then Chessington world of Adventures. Two swarms two weeks apart and on the same bit of fence. And they say they have no bees near by.
