Boston-New York-Washington Region

The Boston-New York-Washington corridor is one of America's prime sites for butterfly observation. Complete with 300 striking full-colour photographs, this is the first field guide to approach lepidoptery in the manner of popular ornithology. Containing the most accurate and up-to-date information, the book describes many previously unpublished identification marks and offers a wealth of practical advice on locations and watching and photographing butterflies.
