Written by Dr. Gordon Pratt, this unique book discusses 98 species found in and around Joshua Tree National Park. For each species, there is life cycle and food plant information beyond what is typically found in butterfly guides. Lavishly illustrated with over 600 photos, this book functions as both a guide for the uninitiated and a reference work for the seasoned lepidopterist. The emphasis on caterpillar food plants and the immature stages of the butterflies sets the book apart. And while the focus in on Joshua Tree, most of the species are found elsewhere, some even in our own backyards, making the book a valuable resource for nature lovers.
