Käyttäjän rcavasin tunnistukset

Observed from a distance alongside the Park Drive Reservation Trail in the Rosedale neighborhood of the City of Toronto.

The question mark can be differentiated from the closely related eastern comma (Polygonia comma [Harris]) by the silvery "question mark" in the middle of the hind wing, its larger size, the more strongly hooked forewing margin, and longer hind wing tail. The "dot" of the "question mark" is occasionally reduced or absent.
