Butterflies and Moths of Mississauga and Oakville Including the Riverwood Conservancy, Rattray Marsh, Lion’s Valley Park and Bronte Creek

I’ve been slowly working through my photos of butterflies and moths and trying to correctly identify them with the help of e-Butterfly, an online butterfly sighting reporting website, BugGuide.net, the ROM Field Guide to Butterflies of Ontario and the Peterson Field Guide to Moths of Northeastern North America. It’s been an adventure because although I knew that I was seeing different types of skippers and moths, I wasn’t sure what types they were. So I’m going to post some of my identified photos here for anyone else who is curious about what types of butterflies and moths can be found in Mississauga, Oakville and nearby areas.

This post will be updated as I make new finds either in the wild or in my older photos!

Many photos can be seen at a larger size by clicking on them.

The Painted Lady and American lady butterflies look very similar. On the underside the American Lady only  has two large eye dots on the hind wing. On the top side, the “eyes” on the hind wings of the American Lady are larger and often blue or purple. There are other differences which a good guide like the ROM Field Guide to Butterflies of Ontario will point out.
