'The Making of a Classic' - The first hand story with Zoe Randle

Making a book about Britain and Ireland’s larger moths was always going to be a mammoth task.

The result is a landmark publication – the first ever atlas of all macro-moths in Britain, Ireland, the Isle of Man and the Channel Islands. Zoe Randle tells the story
