Islands are special places; they can be havens for unique plants and animals and refuges for wildlife. This book investigates the biogeography of butterfly species over the British islands, particularly the factors that influence their presence on the islands and that have made each island's butterfly fauna distinctive. The book contains a full log of records of species on the islands and much supporting information. The first three chapters set the scene, illustrating the basics of island biogeography theory, their changing circumstances during the current Holocene interglacial, and studies of natural history of British butterflies that mark the islands as the most intensively studied region for wildlife in the world. The book advances by increasing resolution downscale from a European continental perspective, through patterns and changes on the British mainland, a comparison of the two dominant islands of Britain and Ireland, to a close inspection of the dynamics of species on the multitude of offshore islands. Detailed investigations include contrasts in species' richness on the islands and then of the incidences of each species. Case studies highlight the continual turnover of species on islands. Attention is then given to evolutionary changes since the time that glaciers enveloped Europe. A powerful message is conveyed for the maintenance of butterfly species on the smaller British islands now experiencing population losses at a rate unprecedented since the spread of the last ice sheets: the incontrovertible importance of maintaining populations of species on nearby mainland sources for islands as pools for future migrants.

Essential guide to the specialist literature for the identification of British insects and arachnids.

Fredrik Sjöberg's Swedish bestseller about summer, islands, freedom and boundaries. 'The light, the warmth, the smells, the mist, the birdsong - the moths. Who can sleep? Who wants to?' Fredrik Sjöberg finds happiness in the little things. Millions of them, in fact. This beguiling bestseller is his unique meditation on collecting hoverflies. It is also about living on a remote Swedish island, blissful long summer nights, lost loves, unexpected treasures, art, nature, slowness, and how freedom can come from the things we least expect. 'Full of charm, a book about how to find meaning in life' Melissa Harrison, The Times, Books of the Year 'I often return to The Fly Trap, it remains close to my heart. The minute observations from nature that reveal sudden insights into one's life. Sometimes I almost think that he wrote it for me' Tomas Tranströmer, winner of the Nobel Prize in Literature 'Charming, witty and original' Patrick Barkham, Guardian 'Nature writing that can laugh at itself, a real tonic' Gregory Day, Sydney Morning Herald 'Delightful, at once informative and often humorously digressive . . . a humane man of wide-ranging curiosity, Sjöberg writes with infectious passion' Paul Binding Independent Fredrik Sjöberg collects hoverflies on the island Runmarö, in the archipelago east of Stockholm. He is also a literary critic, translator, cultural columnist and the author of several books including The Art of Flight and The Raisin King, which form a trilogy with The Fly Trap.
