Dragonflies are a beautiful, important and conspicuous component of freshwater, whether still or flowing. South Africa's dragonflies are particularly interesting as many are special or endemic to the area, making it a part of the world of great conservation significance. This book discusses this exciting dragonfly fauna. Dragonflies are a beautiful, important and conspicuous component of freshwater, whether still or flowing. They are also important indicators of freshwater quality and condition, which is significant for current and future conservation initiatives in South Africa. The country's dragonflies are particularly interesting as many are special or endemic to the area, making it a part of the world of great conservation significance. Sadly however, many of these endemic species are highly threatened, especially by invasive alien trees which shade out their habitat. This book is about this exciting dragonfly fauna. Besides aiming at increasing awareness of these lovely and sensitive insects, it enables their identification, using several approaches, from simple flick-through to the use of comprehensive identification keys. Each species is also given a Dragonfly Biotic Index, covering a spectrum from the most common, widespread and tolerant species through to the most threatened, rare and sensitive ones.

Few animal groups can represent the greatest (insects) and most threatened (freshwater) biodiversity on Earth as well as dragonflies, perhaps the best-known and most colourful of all aquatic insects. Extending from Sudan and Somalia to Zambia and Mozambique, including the entire eastern half of the Congo Basin, this book covers a third of Africa.
This Atlas and Red List details the outcomes of the Southern African Reptile Conservation Assessment (SARCA), the most thorough reptile assessment project ever conducted in Africa. The conservation status of the 422 recognised species and subspecies of reptiles of South Africa, Lesotho and Swaziland was evaluated against IUCN guidelines, based on detailed distribution maps, published literature and the collective expertise of leading herpetologists. This important publication includes, for the first time, colour photographs of all snakes, lizards, tortoises, terrapins, turtles and crocodiles of the region, as well as detailed maps illustrating their ranges.

Additional photographs show species in their specific habitat and illustrate key behaviour. Beautifully presented and authoritative, this book will appeal to anyone with an interest in South Africa’s insect life, and to nature lovers in general.
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
In this fully revised edition of A Guide to Dragonflies & Damselflies of South Africa, all 164 species known to occur in South Africa, Lesotho and Swaziland are described and illustrated, grouped according to family (six dragonfly and six damselfly families). The species entries feature scans of live insects (close-up and side-view images) and photographs of specimens in their natural environment and showing key behaviours. Detailed descriptions focus on size, identifying features and occurrence. An introductory chapter unpacks the life cycle, behaviour, biology and breeding of this fascinating group of insects. Presented in a classic field guide format, this revised edition now also features: expanded annotations to all illustrations, highlighting diagnostic features to ensure accurate identification; updated distribution maps; additional colour plates and photographs. Beautifully designed, informative and authoritative, this book will appeal to anyone with an interest in South Africa’s insect life, and to nature lovers in general. Sales points: Text and distribution maps fully updated and revised; lavish colour plates make ID easy; growing area of interest; the authors’ two previous books on this topic were well received and have sold through (now out of print).

Dragonflies and Damselflies documents the latest advances in odonate biology and relates these to a broader ecological and evolutionary research agenda. Despite being one of the smallest insect orders, dragonflies offer a number of advantages for both laboratory and field studies. In fact, they have been crucial to the advancement of our understanding of insect ecology and evolution. This book provides a critical summary of the major advances in these fields. Contributions from many of the leading researchers in dragonfly biology offer new perspectives and paradigms as well as additional, unpublished, data. The editor has carefully assembled a mix of theoretical and applied chapters (including those addressing conservation and monitoring) and achieves a balance of emerging and established research topics, providing suggestions for future study in each case. This accessible text is not about dragonflies per se but an essential source of knowledge that describes how different sets of evolutionary and ecological principles/ideas have been tested on a particular taxon. It will therefore be suitable for graduate students and researchers in entomology, evolutionary biology, population and behavioural ecology, and conservation biology. It will of course be of particular interest and use to those working on insects and an indispensable reference text for odonate biologists.
Dragonflies and damselflies are some of the most beautiful, fragile and resilient insects found in the natural world. With their complex behaviours, astonishing aerobatic skills and preference for freshwater habitats, they are a very rewarding group of animals to observe in the field. Dragonflies and Damselflies of Britain and Western Europe features all 98 species found in the region. Packed with outstanding photography, this comprehensive book includes close-up illustrations to highlight key identification features, diagrams of wing venation, and detailed guides to dragonfly larvae and exuviae. Each species account includes an accurate distribution map and information on field characteristics, confusion species, habitat and ecology. An introduction to the life cycle of Odonata, guidance on when and where to look for them, and the best ways to observe and photograph dragonflies and damselflies in the field are also included. These sections, combined with the identification guides, make this book the ultimate resource for any field naturalist or entomologist interested in these incredible insects.
