Question mark butterfly
Polygonia interrogationis
Butterfly
Ragged-edged orange anglewing named for the small silver question-mark shape on the underside of the hindwing. Caterpillars use a mixed host palette that includes elms, hackberries, hops, nettles, false nettle, and clearweed; adults behave more like woodland sap-feeders than flower specialists, visiting tree sap, rotting fruit, carrion, and dung before turning to nectar. The winter-form adults shelter through cold weather, making them one of the early butterflies on warm spring days.
Conservation
Globally secure (NatureServe G5) and assessed Least Concern by the IUCN; not a US-listed species. The useful garden action is to keep host trees and weedy-edge larval hosts available, plus tolerate sap/fruit-feeding habitat rather than treating the species as a nectar-border-only butterfly.
Plants in the catalog
Larval host plants · 2
American elm is listed among the question mark butterfly larval hosts; DED-tolerant elm plantings can therefore support this woodland anglewing as well as eastern comma and mourning cloak.
BAMONA and the species literature list hackberries (Celtis) among question mark butterfly larval hosts; common hackberry is the catalog Celtis anchor for this documented genus-level relationship.
Range
Southern Canada and the eastern United States west to the eastern Rocky Mountains, with southern records into Arizona and Mexico; migratory and multi-brooded in much of the range.
