Butterflies of Ontario - List 

This comprehensive list includes some species that can no longer be found in Ontario ( extirpated ), some that are irregular immigrants, 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 Colin Jones, Ross Layberry, and Alan Macnaughton. Ontario Butterfly Atlas Online. (November 2013). Toronto Entomologists’ Association: http://www.ontarioinsects.org/atlas_online.htm 

Printed checklists are available from  The Hamilton Naturalists Club
