内容简介

Visit any pond on a summer day and the air will be alive with dragonflies and damselflies--shimmering aerobatic daredevils that dart above the water and even into nearby fields and woodlands. Organized for easy use in the field, this abundantly illustrated guide, with more than 400 color photographs, is the first to cover Georgia's dragonflies and damselflies (odonates). It details more than 150 species--species that are also the ones most likely to be seen throughout the U.S. Southeast north of Florida.The guide first explains dragonfly and damselfly body parts, taxonomy, life cycles, and habitats; discusses conservation issues; and offers tips on observing and photographing odonates. Later chapters, organized according to the ten odonate families, such as spreadwings, darners, spiketails, and emeralds, provide general family information followed by accounts of individual species. The beautifully illustrated species accounts describe general appearance and key identification features, distribution, habitats, life history and behavior, and conservation. Supplementary materials include suggestions for the best places to watch odonates in Georgia, a comparative listing of species' level of endangerment, and the date range during which each species can be seen.Odonates are easy to find and observe, and because they display an astounding variety of colors, sizes, and behaviors, they are popular with birders, butterfly watchers, and other nature enthusiasts. This guide will be welcomed by everyone who wants to learn about odonates and their habitats and what can be done to help protect them.Included in species accounts: beautiful, detailed photos that show odonates from angles important to determining species, sex, or agecommon and scientific namesimportant features for field identification, with tips on distinguishing between similar-looking speciestypical behavior of the species, including breeding and feeding habitsoccasional commentary on taxonomy or other notable featurescolorful quick guide, with a range map, incidence information, sizing graphics, and flight period informationAdditional features: listing of twenty ideal sites around the state for odonate watchingnotes on infrequently sighted speciesratings for each odonate's conservation status, from most critically imperiled to most stable specieschronological listing of flight dateslisting of additional resources: books, organizations, Web sites, and equipment suppliersglossary and index
