Ontario's Butterflies are divided into 5 families:
The pages in these sections are organized taxonomically, according to family, subfamily, and species. Clicking on any of the links above will bring you to a page for the corresponding butterfly family. On these family pages you'll find thumbnail images for each species which provide access to the corresponding species pages. On each of these species pages you'll find a selection of images, a link to the Ontario Butterfly Atlas showing where that species has been reported, and a link to the corresponding Butterflies of Canada page which provides descriptive information.
These sections include most of the species found in Southern and Eastern Ontario, with the exception of a few regional rarities and infrequent migrants. A number of species found strictly in Northern Ontario are missing, but I hope to add them in the future. The species lists are derived from a number of sources listed on the references page.
