In Hymenoptera, Marshall has 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 color photographs identified with help from many of the world's best hymenopterists, this volume provides the reader with a colorful and enjoyable introduction to a huge group of organisms, along with an overview of the diversity of fascinating families included in the group. 640 pages hc
