Dr. Walker and Dr. Corbet make a signal contribution in gathering together all available information on the dragonflies of Canada and Alaska. The order as a whole and the zygoptera are covered. The treatment is not confined to taxonomy and geographical distribution, but includes data on habitats, seasons of adult life, and brief notes on habits when these are available.

Set includes revised editions of some issues.

Written in language that is accessible to the sports fisherman and the naturalist and with over 1,000 original illustrations, the book includes features such as coverage of all insect families and genera important to fly fishing; comphrensive treatment of the biology of all life stages of aquatic insects including terrestrial as well as aquatic stages; special chapters on shore dwelling insects, insects associated with aquatic vascular plants, residents of tree holes and plant cups, aquatic arachnids and freshwater crustaceans.

Dragonflies are conspicuous insects. Many are large; they fly strongly; most are brightly coloured. As a result, they have been collected extensively. Their larvae are less familiar. 'Mud-eyes', as some are called, are drab, and almost all live in fresh waters, out of sight. They are, perhaps, best known as bait for freshwater fish. The dragonflies constitute a very distinct order of insects, the Odonata. In Australia, two suborders are represented: damselflies (Zygoptera), generally very slender insects, the fore- and hindwings similar in shape and venation and commonly held closed above the body at rest (Figs 46-63), the larvae with external gills on the end of the abdomen (Figs 4A-C, E); and dragonflies proper (Anisoptera), stouter, stronger-flying insects, the fore- and hindwings more or less dissimilar in shape and venation and commonly held spread at rest (Figs 64-101), the larvae with internal, rectal gills (see Chapter 2). Living representatives of the third suborder (Anisozygoptera) are confined to Japan and the Himalayas. The term 'dragonfly' is commonly applied to the entire order.

Students of entomology at every level need to be able to identify and classify the insects they study. How to Know the Insects has helped generations of readers learn to do just that. The key to insect ordersthe largest section of the bookuses both written text and myriad illustrations to provide identification details down to the family level as well as for common species of each family. In addition, Bland and Jaques provide accounts of insect natural history, the basic biology of each order and of most families, and extensive material in finding, collecting, and preserving insects. The handbook serves as a valuable learning tool or reference for undergraduate and graduate students of entomology, science educators, insect collectors, and anyone interested in the diversity of insects.

Offering a complete accounting of the insects of North America, this handbook is an up-dated edition of the first handbook ever compiled in the history of American entomology.By using American Insects, A Handbook of the Insects of America North of Mexico, Second Edition, readers can quickly determine the taxonomic position of any species, genus, or
