An Annotated Checklist Of The Butterflies Of Bentsen Rio Grande Valley State Park And Vicinity PDF Download

Covering the southeast 1/6 of Arizona, this book illustrates and comments on nearly 300 species either found here or are suspected, possible, or claimed to occur here. Including two counties and portions of four others, this book focuses on a unique geographic area known for both its butterflies and birds. As noted by the authors, this black-and-white book is meant to be used in tandem with other color field guides. All of the southeastern butterflies are illustrated with multiple (usually two) b&w photos. The two photos are typically dorsal and ventral and often of male and female. Four color plates showing dorsal views of 90 species are included in the appendices. The text for each butterfly varies from one paragraph for vagrants to half a page for the expected species. Four categories are typically offered for each butterfly, which are: General, larval foodplant, flight period, and distribution.
