Thursday 17 March How many butterflies are there in the Western Palaearctic? Martin Davies will talk about his lifelong obsession with butterflies. From his first butterfly book to the wonderful handbooks available today, the beauty and diversity of butterfly species has never ceased to amaze him. We may think we know how many butterfly species there are in Europe but how has our understanding of this improved over the years? Lots of wonderful places and species are featured in this wide-ranging detective story, from the Atlantic to theAltai and the Arctic to the Atlas.
