Has computer-enhanced photographic illustrations on plain backgrounds. More species are illustrated per page than in Glassberg's Butterflies Through Binoculars series. This can make it somewhat easier to use than Glassberg's books. Illustrates all North American species, and is in a compact field guide format. The serious butterflier will want to have this in addition to Glassberg's works.

I do not have the previous version, but I get the impression that the content is identical. Perhaps somebody who has seen both editions can confirm this...
