For the last three or four days bumble bees have been frequenting the marsh and fields beside the Egg. They are in and out of the mouse holes on the riverbank where they may be seeking shelter from the newly arrived colder weather, or a new home for a nest. I have found quite a few curled up dead on the ground or really lethargic and seemingly close to death. There are 25 species of bumble bee in the UK but I cannot recognise the differences. With the aid of a microscope and magnifying glass my drawings may soon start to answer this question.
