A groundbreaking photographic field guide to almost all of Mexico's butterfly species and many of Central America's This is a revised second edition of a groundbreaking photographic field guide to the butterflies of Mexico and Central America. Written by Jeffrey Glassberg, the pioneering authority on the field identification of butterflies, the guide covers more than 2,000 species and features over 3,700 large, gorgeous color photographs, the very best images available, accompanied by authoritative facing-page text. This second edition includes more species, more than 1,500 new photos, and updated text, maps, and species names. And range maps, field marks, and host plants are included for all Mexican butterflies. The result is an ideal field guide that will enable you to identify almost every butterfly you see. A revised second edition of a groundbreaking guide, featuring more species, more than 1,500 new photos, and updated text, maps, and species names The first complete guide to Mexican butterflies Covers almost all of Mexico's more than 1,700 species, plus many Central American species, including more than two-thirds of those in Costa Rica Written by the pioneering authority on the field identification of butterflies Beautifully illustrated with more than 3800 color photographs that show almost all known Mexican species and about 90% of Costa Rican and Panamanian species Range maps, field marks, and host plants for all Mexican species Authoritative facing-page text An invaluable tool for field identification

"The Neotropical lycaenid hairstreak genus Paraspiculatus is unusual because of a high frequency of sympatry in the Upper Amazon Basin coupled with negligible interspecific variation of male genitalic structures and absence of male secondary sexual traits. Male sexual structures are postulated to promote species recognition by females and to contribute to reproductive isolation, for which reason a high incidence of sympatry in Paraspiculatus would not be expected. A revision of Paraspiculatus was feasible because we increased the number of study specimens more than five-fold (by the extensive use of rotting fish as a bait for males) and sequenced the "barcode" part of the mitochondrial gene CO1 for almost all species. We recognize 19 Paraspiculatus species based on male wing patterns, of which ten are newly described and registered with ZooBank. We partition the 19 species into ten species complexes, which are monophyletic in all analyses of morphological characters, CO1 sequences, and a combined dataset. Male Paraspiculatus are attracted to traps baited with rotting fish in eastern Ecuador, but elsewhere this attraction is less frequent or absent. Using the behavior of other eumaeines as context, we briefly discuss these observations with respect to Paraspiculatus biology. Ten of 19 Paraspiculatus species are sympatric in the Upper Amazon Basin below 1,250 m. Five of these sympatric species are from a single species complex. This instance of apparent in situ diversification is responsible for much of the sympatric diversity in Paraspiculatus in the Upper Amazon Basin."--Provided by publisher.
