Butterfly Watching is a Perennial Summer Activity, and as the Growing popularity of butterfly conservatories in Ontario and British Columbia can attest, butterflies are a continuing source of delight and interest to Canadians. The Butterflies of Canada is the first comprehensive guide to all the butterflies found in Canada. Based on the national butterfly collection maintained by Agriculture Canada, it contains descriptive individual accounts for all of the close to three hundred butterfly species recorded in Canada, including descriptions of early stages of individual species, subspecies, and a list of key features.
