The sap is starting to escape the cracks in the oak along the Red Deer trail at the Riverwood Conservancy in Mississauga. There were several Mourning Cloaks, Commas, Question Marks and moths today taking advantage of it.
One was this one, which I hope is my first Compton Tortoiseshell. (I'm having more luck identifying butterflies when I can get a photo to study in detail later.)
Can anyone confirm the id?
