List of Ontario Butterflies

This comprehensive list includes some species that can no longer be found in Ontario ( extirpated ), some that are irregular strays, and others that are regional rarities. I'm still working on getting photos of some of these species, especially those species that are only found in Northern Ontario.

Clicking on the underlined names will take you to the corresponding species page.

This list is based on Alan Macnaughton, Ross Layberry, Rick Cavasin, Bev Edwards and Colin Jones. Ontario Butterfly Atlas (February 2020) . Toronto Entomologists’ Association: https://www.ontarioinsects.org/atlas/index.html

Printed checklists are available from The Hamilton Naturalists Club
