"In 1993, the publication of Jeffrey Glassberg's Butterflies through Binoculars popularized butterfly-watching nationwide. This field guide did for butterflying what Roger Tory Peterson's guides had done for birding: make it possible for the serious amateur to identify the great majority of species through close inspection with binoculars" (Sharon Stichter, Butterflies of Massachusetts)

“Books like these could open the world of butterflies to much more of the general public.” (Paul Ehrlich in Science magazine)
