Eastern Comma in Southern Ontario?
Good day,
I took a picture of this butterfly while on a lengthy bike ride in southern Ontario, Canada. I was on the ‘Rail Trail’ between Brantford and Hamilton Ontario, a path that was once used by trains, now a trail used for public leisure. From what I’ve seen and read, I believe it may be an Eastern Comma. The problem is that the pattern and colouring on the rear wings doesn’t match those I’ve seen on that particular species. I’ve attached the image file to this email. Feel free to use it on your site if you decide to respond. Thanks for your time,
Terry Howes

Hi Terry,
We first opened your email yesterday, but were unable to post at the time. Trying to sort through all of our incoming mail to relocate your letter was no small undertaking. This is a Questionmark, Polygonia interrogationis, the black form. The Questionmark is the only Anglewing with, according to Jeffrey Glassberg, “a small black horizontal bar on the subapical FW above.” The black form, with the dark hind wings is the summer form.
