Mike LeRoy has written a review of a new book by Richard Lewington which was published in February:  Pocket Guide to the Bumblebees of Great Britain and Ireland (Bloomsbury 2023)

Mike says: “Bumblebees look as though they should be easy to identify, but often they are not. This new book is far better at aiding accurate identification than any I have ever used – which is many!”

The full review is can be found here: Pocket-Guide-Bumblebees-Book-Review

Learning more about bumblebees to enable you to identify them will be a good basis for then sending in your Sightings and submitting them as records.
