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 bewitching book charts Patrick Barkham's quest to find all 59 - from the Adonis Blue to the Dingy Skipper - in one unforgettable summer. Barkham brings alive the extraordinary physical beauty and amusingly diverse character of our butterflies. He witnesses a swarming invasion of Painted Ladies, experiences the curse of the Purple Emperor, makes a euphoric sighting of an exceedingly rare migrant and as summer draws to a close, suffers from butterfly burnout. He meets some deeply knowledgeable and eccentric butterfly obsessives and reconnects with lovely, overlooked corners of our countryside. As he goes, he looks back at the butterfly collectors of the past and ahead to a future in which many of our butterflies will struggle to survive on an overcrowded and overheating island. Wry, attentive, full of infectious delight and curiosity, written with a beautifully light touch, Butterfly Isles will become a classic of British nature writing.
