Beetles are the largest and most studied order of insects, some of which are beneficial as biological control agents. Alphabetically lists all species and subspecies of beetles known to Canada and Alaska under their respective genus-group names. Includes a brief introduction for every family treated and an index to all supraspecific names.

"Moths and butterflies (Lepidoptera) are one of the most diverse and economically important groups of insects, with approximately 157,000 species worldwide. This book establishes a definitive list of the species that occur in BC, and clarifies erroneous records in past works. It provides a knowledge baseline that will be useful to resource and conservation managers, biodiversity researchers, taxonomists, amateur collectors, and naturalists."--Back cover.
