David Beadle grew up in Kent, England, where he had no interest in the natural world until he was gripped by an obsession with birds in his late teens. It was while working at a bird observatory that David became interested in moths, an interest that soon grew to an all-consuming passion. He now lives in Toronto, Ontario, with his wife and son, and he has photographed more than 2,000 species of moths in that province alone.

In addition to his work with moths, David has contributed to over thirty books and countless journals, including New World Warblers and A Field Guide to the Birds of Chile.
