Polygonia interrogationis, commonly called the question mark butterfly, is a North American nymphalid butterfly. It lives in wooded areas, city parks, generally in areas with a combination of trees and open space. The color and textured appearance of the underside of its wings combine to provide camouflage that resembles a dead leaf. The adult butterfly has a wingspan of 4.5–7.6 cm (1.8–3.0 in). Its flight period is from May to September. "The silver mark on the underside of the hindwing is broken into two parts, a curved line and a dot, creating a ?-shaped mark that gives the species its common name."
Like other species in the order of Lepidoptera, the question mark is a holometabolous insect that undergoes four life stages. These four life stages are embryo (egg), larva (in this case, caterpillar), pupa (chrysalis), and imago (or adult/butterfly).
After the male has found the female perching on a tree or in the grass, courting ensues, after which the mating of the two occurs. Females lay eggs singly or stacked under leaves of plants that are usually not the hosts. The young hatchlings must then find their food source to survive.

GBIF citizen-science records
It is estimated from how often the Question Mark is recorded against all the insects logged in San Antonio (250 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
