Excerpt from Bioquip,"This monograph is a summary of knowledge of the biodiversity, systematics, distribution and biogeography of the 153 known northwestern North American stoneflies. Following a brief introduction, it contains a key to families. It then provides new keys to all species of adults and the lowest possible identifiable taxon of nymphs. Type locality, geographic range/regional distribution, and biology are given for each species. The book is generously illustrated with full-page drawings of adults in addition to line drawings of diagnostic characters."

Regions covered include Alaska, Yukon, Western Northwest Territories, Alberta, and British Columbia. A must-have for anyone working on aquatic insects in the region.
