Caterpillar foods: nettle, elm, hackberry, Japanese hops (Bugguide)
Very similar to Eastern and Gray Comma. Above, Question Marks have 4 spots in the PM band, rather than 3 in Commas. The overwintering form has violet edges on its wings and tails. On the underside they have two white marks which together look like a question mark.
