By Rosser W. Garrison, Natalia von von Ellenrieder, Jerry A. Louton

Dragonfly Genera of the hot World is a fantastically illustrated and complete consultant to the taxonomy and ecology of dragonflies in North, center, and South the United States. A reference of the best quality, this booklet unearths the outstanding attractiveness and complexity of this diversified order.

Although Odonata—dragonflies and damselflies—are one of the such a lot studied teams of bugs, earlier there was no trustworthy capacity to spot the recent global genera of both workforce. This quantity presents totally illustrated and up to date keys for all dragonfly genera with descriptive textual content for every genus, observed via distribution maps and 1,595 diagnostic illustrations, together with wing styles and features of the genitalia.

For entomologists, limnologists, and ecologists, Dragonfly Genera of the recent World is an necessary source for box identity and laboratory research.
