Links — [CBIF] — are to Butterflies of Canada on the Canadian Biodiversity Information Facility web site where you’ll find more photographs, descriptions, ranges, habitat, and more. The small images next to each butterfly’s name are from Butterflies of Canada. They show upper wing on left and under wing on the right and show the relative size of each species. Wingspans, flight times, and larval food are also from Butterflies of Canada.
