This beautifully presented work provides a thorough guide to the butterflies of the Canadian Province of Alberta. Life-size colour photographs complement the descriptions of every species and subspecies known or expected to occur in Alberta, and colour pictorial keys assist in their identification. Each species account includes habitat requirements, life history, and distribution information. Colour maps illustrate species ranges in North America and confirmed recordings in Alberta. There is also general information on butterfly anatomy and biology, and plants which can be cultivated to attract specific butterfly species.
