Walking a forest trail in Costa Rica, a visitor might be struck by the sight of an iridescent blue morpho butterfly fluttering ahead in the filtered daylight, or an enormous silk moth, as magnificently patterned and subtly colored as a Persian carpet, only emerging to fly at night. Elsewhere, vivid yellow and orange sulphur butterflies flock to puddles to sip the concentrated minerals. Such is the dazzling variety of the butterflies and moths unique to this region.

Gathered by biologists Daniel Janzen and Winifred Hallwachs in the forests of northwestern Costa Rica, 100 tropical butterflies and moths represent the diversity in large-format photographs by Jeffrey Miller that document the dizzying variety of shapes, colors, and markings. The photographs are accompanied by species accounts and images of the corresponding caterpillar. The authors recount these insects' feats of mimicry and migration, lift the veil on their courtship, and show how the new technology of DNA barcoding is changing the picture of Lepidopteran biodiversity.

The authors also tell the success story of Area de Conservacion Guanacaste, where the long-term work of Janzen and Hallwachs, a team of caterpillar collectors, and the participation of neighboring farming communities has deepened understanding of Costa Rica's Lepidoptera and has brought about advances in restoration ecology of tropical habitats, biodiversity prospecting, biotechnology, and ecotourism development.

At the biological crossroads of the Americas, Costa Rica hosts an astonishing array of plants and animals—over half a million species! Ecotourists, birders, and biologists come from around the world, drawn by the likelihood of seeing more than three or four hundred species of birds and other animals during even a short stay. To help all these visitors, as well as local residents, identify and enjoy the wildlife of Costa Rica, Carrol Henderson published Field Guide to the Wildlife of Costa Rica in 2002, and it instantly became the indispensable guide.

Now Henderson has created a dedicated field guide to more than one hundred tropical butterflies, moths, and other invertebrates that travelers are most likely to see while exploring the wild lands of Costa Rica. He includes fascinating information on their natural history, ecology, identification, and behavior gleaned from his forty years of travels and wildlife viewing, as well as details on where to see these remarkable and beautiful creatures. The butterflies, moths, and other invertebrates are illustrated by over 180 stunning and colorful photographs—most of which were taken in the wild by Henderson. A detailed and invaluable appendix that identifies many of Costa Rica's best wildlife-watching destinations, lodges, and contact information for trip-planning purposes completes the volume.

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.
