About Polygonia interrogationis (Fabricius, 1798)
Polygonia interrogationis, commonly known as the question mark butterfly, is a nymphalid butterfly native to North America. It inhabits wooded areas, city parks, and generally any locations that have a mix of trees and open space. The color and textured appearance of the underside of its wings work together to create camouflage that looks like a dead leaf. Adult question mark butterflies have a wingspan ranging from 4.5 to 7.6 cm, or 1.8 to 3.0 inches. Their flight season runs from May to September. This species gets its common name from a silver mark on the underside of its hindwing: the mark is split into two parts, a curved line and a dot, that together form a question mark shape.
