"The life blood of Dr. Jeffrey Glassberg's new field guide are the superb photographs of living butterflies. Over 300 species of butterflies occurring in the eastern half of the United States and southeastern Canada are covered. The uniformly high quality of the photographs is instantly obvious....Glassberg and all those who helped him are to be commended on having produced a truly state of the art field guide."--News of the Lepidopterists' Society
