Question Mark Butterfly
Question Marks resemble Eastern Commas, but look for the fourth "flattened dot" at the end of the row of three dots. Question Marks have this fourth flattened dot; Eastern Commas almost never do (except in rare cases). Question Marks are also slightly larger on average, but there is some overlap in their size ranges.
This is the "umbrosa" or summer form of the Question Mark butterfly. Notice that the lower wings are dark, as opposed to the lighter winter forms above.
This is the underside of a Question Mark butterfly. The small white marking gives this species its name. Question Marks are a woodland species, and they rarely nectar at flowers. However, I have occasionally seen Question Marks taking nectar from butterfly bushes (buddleia), or in the case of the individual at left, a spring-blooming lilac.
This Question Mark butterfly was resting along the boardwalk at Cedar Bog. Question Marks fly from early spring through late fall. I have found them every month from March through November.
Questions Marks have different forms depending on the season. The individuals at left and above are the winter form. In wintertime, these butterflies have lighter-colored hindwings and a thin white (or pale blue) border on their wings. This winter-form Question Mark was photographed at Oakes Quarry in October 2024.
