Butterflies animate our summers but the 59 butterfly species of the British Isles can be surprisingly elusive. Some bask unseen at the top of trees in London parks; others lurk at the bottom of damp bogs in Scotland. A few survive for months while other ephemeral creatures only fly for three days. Several are virtually extinct. This book charts Patrick Barkham's quest to find all 59 - from the Adonis Blue to the Dingy Skipper - in one unforgettable summer.
