Everyone is familiar with the sight of tiger swallowtails wafting over the prairie, delighting us with their black-and-yellow beauty, and all auto travelers are used to seeing bright orange monarchs floating over the highways in fall. But how many of us take the time to appreciate the less common butterflies of the Midwest, such as the little wood satyr or the silver-spotted skipper? In Butterflies in Your Pocket, Steve Hendrix and Diane Debinski have created an easy-to-use and inexpensive way to identify and enjoy these winged jewels. This new Bur Oak Guide illustrates sixty-five species and is one of the first to use digital photos instead of drawings. The guide shows sexual differences between males and females, seasonal forms, and both the upper and undersides of wings when these are critical for proper identification. In addition to common and scientific names, it also provides information on size, habitat, preferences, and months when each species can be found. The popularity of butterfly gardens and an increase in prairie restoration have raised awareness of the beauty of butterflies as well as their threatened status. Butterflies in Your Pocket is a helpful guide to appreciating and learning about these fragile midwestern inhabitants.
