About this site:

This site provides a comprehensive guide to the butterflies of the Ottawa-Gatineau region of Canada, with English and French common names, scientific names, and other useful information.
Most of these species can be found throughout Eastern Ontario and West Quebec, not just in Ottawa-Gatineau.  In fact, many of these species can be found throughout much of North America.

Each butterfly species has its own page, and these pages are organized by subfamily and family.  If you're unfamiliar with the wide range of butterflies found in our area, you might want to start at the Families page. This will give you an idea of how our butterflies are classified, but feel free to dive in anywhere and explore!

From each family page, you can click on the image of any species to get to the corresponding species page.

On each species page, you'll find a link to the corresponding Butterflies of Canada page which provides additional descriptive information ( in English and in French ).  

Although this website can be used as an aid to butterfly identification, it is not intended as a replacement for a comprehensive field guide ( see references ).  It should be remembered that most species are variable, and can sometimes be difficult to distinguish from their close relatives (especially in  photographs). 

This site is not sponsored by or affiliated with any particular organization.  However, I did have help (see Acknowledgements ).

This is a work in progress, and will be updated as I get additional images.

English & Latin names and Taxonomical ordering align with: Jones, C.D.  2012. Checklist of Ontario Butterflies,  Hamilton Naturalists Club, Ontario Ministry of Natural Resources & Ontario Nature. ( checklist is available from The Hamilton Naturalists Club )

French common names (generally) follow  Le Guide des Papillons du Québec, 1999. Louis Handfield, Broquet, Ottawa.
