Birding and butterfly watching have been popular outdoor activities for decades. Now, dragonfly watching is catching on as a fascinating and enjoyable pursuit. Dragonflies are large, colorful insects with amazing and easily observed behavior. Noted entomologist Dr Robert Cannings introduces students, naturalists and outdoor enthusiasts to the world of dragonflies. In this compact book, he shows readers where to find dragonflies and how to watch and study them in the field. In the introduction, Dr Cannings outlines the natural history of these insects - their structure, life cycles, habitats and behavior. Then he describes the 88 species known in British Columbia and the Yukon, noting habitat preferences and distribution. To make identification easy, each description has one or more color photographs and comparisons with similar species.
Dragonflies (Odonata), represented by over 6000 known species, are unique insects. In more than one feature they differ, at the very first glance, from all other insect superorders including their nearest allies, the mayflies (Ephemeropteroidea). The Zygoptera and Anisoptera, on the other hand, are the dominant groups. Being voracious predators in both immature (aquatic) and adult (aerial) stages they are important elements of all, except the drier (or high alpine) environments in temperate and tropical regions, occupying a position at the apex of the food chain of invertebrate life. Many dragonfly species are tested biological control agents for several disease-transmitting vector mosquitoes, especially Aedes species. They are also ideal organisms to be used as indicators of water pollution and contamination. Many species serve as intermediate hosts of fluke parasites of birds, and thus are important in the transmission of parasitic diseases, especially of domestic poultry and wild ducks. Because of their unique morphology and physiology, dragonflies are used extensively in the study of many biological phenomena. All these subjects are discussed in this unique book comprising twenty three articles written by expert odonatologists from different parts of the world. The book is written in a lucid and comprehensible language, and will likely be useful to both the professional and amateur alike.

A lavishly illustrated introduction to the world's dragonflies and damselflies Dragonflies and damselflies are often called birdwatchers’ insects. Large, brightly colored, active in the daytime, and displaying complex and interesting behaviors, they have existed since the days of the dinosaurs, and they continue to flourish. Their ancestors were the biggest insects ever, and they still impress us with their size, the largest bigger than a small hummingbird. There are more than 6,000 odonate species known at present, and you need only visit any wetland on a warm summer day to be enthralled by their stunning colors and fascinating behavior. In this lavishly illustrated natural history, leading dragonfly expert Dennis Paulson offers a comprehensive, accessible, and appealing introduction to the world’s dragonflies and damselflies. The book highlights the impressive skills and abilities of dragonflies and damselflies—superb fliers that can glide, hover, cruise, and capture prey on the wing. It also describes their arsenal of tactics to avoid predators, and their amazing sex life, including dazzling courtship displays, aerial mating, sperm displacement, mate guarding, and male mimicry. Dragonflies and Damselflies includes profiles of more than fifty of the most interesting and beautiful species from around the world. Learn about the Great Cascade Damsel, which breeds only at waterfalls, the mesmerizing flight of Blue-winged Helicopters, and how the larva of the Common Sanddragon can burrow into sand as efficiently as a mole. Combining expert text and excellent color photographs, this is a must-have guide to these remarkable insects. A lavishly illustrated, comprehensive, and accessible natural history that reveals the beauty and diversity of one of the world’s oldest and most popular insect groups Offers a complete guide to the evolution, life cycles, biology, anatomy, behavior, and habitats of dragonflies and damselflies Introduces the 39 families of dragonflies and damselflies through exemplary species accounts Features tips on field observation and lab research, and information on threats and conservation
Damselflies and Dragonflies (Odonata) of Texas is an indispensable updated reference to the 223 species of odonates distributed throughout the Lone Star state. Included in this volume are detailed species distribution and seasonality information arranged so that users can quickly and easily search by scientific name, county name, or flight season. All information is updated as of 2006. A variety of articles are also included on the natural history, photography, migration, collection and preservation, and diversity of Texas odonates. Whether using the book to find new species records in the deserts of west Texas or perusing articles in the comfort of your home, volume 2 of the Odonata Survey of Texas is an essential guide for both life-long and budding odonatologists alike.
On any warm summer day, you can easily observe damselflies around a vegetated pond or the rocks along the banks of a stream. Like the more familiar dragonfly, damselflies are among the most remarkably distinctive insects in their appearance and biology, and they have become one of the most popular creatures sought by avocational naturalists. Damselflies of Texas is the first field guide dedicated specifically to the species found in Texas. It covers 77 of the 138 species of damselflies known in North America, making it a very useful guide for the entire United States. Each species account includes: illustrations of as many forms (male, female, juvenile, mature, and color morphs) as possible common and scientific names, with pronunciation distribution map key features identifying characteristics discussion of similar species status in Texas habitat, seasonality, and general comments In addition to photographing damselflies in the wild, the author and illustrator have developed a new process for illustrating each species by scanning preserved specimens and digitally painting them. The resulting illustrations show detail that is not visible in photographs. The book also contains chapters on damselfly anatomy, life history, conservation, names, and photography, as well as a list of species that may eventually be discovered in Texas, state and global conservation rankings, seasonality of all species in chronological order, and additional resources and publications on the identification of damselflies.
Winner of the Single Volume Reference/Science award of the Professional and Scholarly Publishing Awards given by the Association of American Publishers Dragonfly Genera of the New World is a beautifully illustrated and comprehensive guide to the taxonomy and ecology of dragonflies in North, Middle, and South America. A reference of the highest quality, this book reveals the striking beauty and complexity of this diverse order. Although Odonata—dragonflies and damselflies—are among the most studied groups of insects, until now there has been no reliable means to identify the New World genera of either group. This volume provides fully illustrated and up-to-date keys for all dragonfly genera with descriptive text for each genus, accompanied by distribution maps and 1,595 diagnostic illustrations, including wing patterns and characteristics of the genitalia. For entomologists, limnologists, and ecologists, Dragonfly Genera of the New World is an indispensable resource for field identification and laboratory research.
A concise, full-colour guide to more than 200 native and introduced plant and animal species found in Vancouver’s famed city park. Vancouver’s Stanley Park is known around the world as a natural oasis in the midst of Western Canada’s largest city. Unlike many urban parks, which are mostly cultivated, the 1,000-acre area now known as Stanley Park is part of the natural rainforest of this region. As much of this natural habitat has been preserved as parkland, Stanley Park is an accessible place to observe much of the native plant and animal life that can be found throughout the south coast of British Columbia and the Pacific Northwest. The Flora and Fauna of Stanley Park is a practical and colourful keepsake, highlighting more than 200 trees, shrubs, wildflowers, berries, seaweeds, birds, land mammals, and shoreline creatures. With clear colour photography, detailed descriptions, etymology, and safety tips and warnings, this book is the perfect go-to guide for visitors to the park, and anyone interested in the rich biodiversity of the Vancouver area and beyond.
