A treasure. Hymenoptera highlights these insects in an incredibly rich selection of colour photographs and text, that serve both in identification and to illuminate their lives and strategies. It is hugely pleasing. Superb. - Bernd Heinrich, biologist and author Stephen A. Marshall's natural history titles - Insects: Their Natural History and Diversity, Beetles: The Natural History and Diversity of Coleoptera and Flies: The Natural History and Diversity of Diptera - are among the most respected books on the insect world published in the last 20 years. More admirable than the books' rigorous science, however, is that they are wholly suitable for a lay audience, including high school students interested in entomology. The books have been adopted as classroom texts at the university level and are on the reference shelves of many practicing entomologists. In Hymenoptera, Marshall has again applied his broad knowledge of insects to the world of wasps, bees and ants. The subject of this book is an enormous one, since Hymenoptera is arguably the largest order of living things. Comprehensive and packed with richly illustrated keys and thousands of colour photographs identified with help from nearly 100 of the world's best hymenopterists, this volume provides the reader with a colourful and enjoyable introduction to a huge group of organisms, along with an overview of the diversity of fascinating families included in the group. Marshall opens with a description of what makes a wasp a wasp, and then introduces the diversity, importance and natural history of the order with copious examples and explanations. Topics include the life histories of wasps, hymenoptera and plants, hymenoptera in history, culture and fiction, kleptoparasitism, and many more. Part two of Hymenoptera is a guided tour of the diversity of the order, with fascinating stops for almost all of the world's 100 or so families of wasps as well as most of the significant subfamilies. Thousands of photos, almost all taken in the field by the author, are used to capture the range of form and function in each family, with pages of photographs of the popular groups - such as bees, hornets and ants - but also with little-known groups ranging from pincer wasps to fairyflies. Essential information about importance, range, behavior and biology is provided for each group, and easy-to-use photographic keys to most families are provided for those wishing to use the book as an identification guide. Like Marshall's companion titles, Hymenoptera will be welcomed by the scientific, academic and naturalist communities, as well as the next generation of entomologists. AUTHOR: Stephen A. Marshall is a Professor Emeritus at University of Guelph, Ontario. He has discovered hundreds of taxa new to science and published over 200 papers on insect systematics and biodiversity. When he is not working at the University of Guelph Insect Collection (Canada's oldest insect collection), he can usually be found in his bug-rich backyard on the banks of the Grand River near his hometown of Fergus, Ontario.
