Roland Wauer's Butterflies of the Lower Rio Grande Valley is the only field guide to cover all the reported species in what he calls the "number one butterfly area" in the country.
His book includes a description of each species, when and where they can be found, a comparison of similar species, and additional remarks on natural history and nomenclature. Full-color photographs of almost all of the butterflies accompany the text. Also includes maps and drawings.
