I guess it may depend on where you are. Around here, and in south Mississauga/Oakville, it's been a great year for butterflies. Red Admirals, Monarchs, Painted and American Ladies and Question Marks arrived early in numbers and their families have multiplied and are now heading back. Also some less frequent visitors like an American Snout.
Painted Lady numbers have been awesome in many parts of Canada this year. Records of huge groups moving south are coming in from across Ontario and east. You may want to check the project to improve info on their migration at e-butterfly.org
(If you haven't already you may want to report your sightings above too. Unlike eBird, e-butterfly doesn't have as many active listers.
Sorry your area hasn't been having as good a summer. Maybe next year!
