This book is an in-depth look at the natural history of each snake and lizard species/subspecies found in Iowa. Each of the thirty-three species accounts includes a sampling of the common names the species has been known by in the past, the first specimens collected in the state, and a brief history of the early Iowa literature related to the species, along with a complete description and a discussion of similar species, distribution in the state, habitat, behavior, threats, foods and feeding, and reproduction. While readers will be able to identify Iowa’s snakes and lizards through its species accounts, identification keys, and beautiful photographs and illustrations, this book is intended to be more than a field guide. What makes it truly unique is the comparison of historic data collected by Iowa herpetologists in the 1930s and 1940s with data collected by the author, along with James L. Christiansen and others, since 1960. Custom maps show the reader how species’ distributions have changed over time.

"Through the combined work of 13 different experts in the field, you'll gain invaluable and unique insight into the life style, behavioral characteristics, and physical appearance of many different species [of snakes]."--Page 2 of cover.

From the rare and docile massasauga, which relies on camouflage to remain unnoticed, to the more familiar bullsnake, which defends itself by hissing loudly and vibrating its tail from an S-shaped striking position, to the eastern racer, often seen crawling at more than three miles an hour during daytime, snakes are beautiful animals with habits both fascinating and beneficial to humans. Their relatives the lizards, most of which are more easily seen and identified, exhibit similarly fascinating behavior. This colorful addition to our series of laminated guides informs both amateur and professional herpetologists about twenty-seven species of snakes and six species of lizards in the Upper Midwest states of Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, South Dakota, North Dakota, Kansas, Nebraska, Iowa, and Missouri. Terry VanDeWalle provides a complete description of each species, both adult and young, as well as distinguishing characteristics for thirty-two subspecies of snakes and two subspecies of lizards: length, color, head and neck patterns, scales, and so on. Also included is information about habitat preferences: forests, wet meadows, and sand prairies, for example. Most helpful for identifying snakes and lizards in the field are his comparisons of similar species and his comprehensive key. Superb photographs by Suzanne Collins of adult and, when needed for identification, young snakes and lizards make this guide the perfect companion for hikers in all kinds of environments whenever a snake ripples across your path or a lizard darts into the underbrush.
