All across the country, butterflies are becoming as popular as birds and wildflowers, especially among people seeking to enjoy the rich natural resources that Texas possesses. John and Gloria Tveten have been studying butterflies in Southeast Texas for thirty-five years, and here they offer their considerable knowledge to everyone who shares their passion for butterflies. In this easy-to-use field guide, the Tvetens describe and illustrate more than 100 species of butterflies that live in Southeast Texas and can often be found across the state. Striking color photographs of living butterflies and caterpillars (a unique addition) show the key marks and characteristics necessary for field identification. The Tvetens' enjoyable and authoritative text describes each species' life history, habits, flight patterns, and characteristic markings. An account of the different butterfly families, from swallowtails to longwings to skippers, precedes the descriptions of the species within each family. The Tvetens also include an interesting discussion of butterfly biology, a complete checklist of area butterflies, an index of butterfly-attracting plants, and pointers to other butterfly resources. This field guide is the first to focus exclusively on Southeast Texas butterflies. It will be the essential reference for everyone seeking a reliable way to identify these butterflies, from field observers to apartment dwellers who wonder what is fluttering around the pot plants on the balcony.
