Species Speyeria diana - Diana

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 bought this book mainly for the caterpillar images.

I grab this book first when I'm looking to identify a butterfly.

Overviews of each region of the state, more detailed sections on habitats such as mountain ranges, deserts, and canyons, and very specific information on individual locations - you'll find out which side of a gulch gets the morning sunlight and how far down a creek the swallowtails puddle.

Other chapters discuss where to go and what to look for in each month of the year (in February, willow ragwort flowers near Sonoita Creek attract Arizona Dusky-Wings), provide brief descriptions of many species of butterflies and skippers, and review the state's butterfly gardens.
