Caterpillar foods: Gerardia, Toadflax (Linaria spp.), and Plantain
Common Buckeyes don’t overwinter in Wisconsin, but they often move north into the state during the summer. Toward the end of the summer I usually see one or two Buckeyes every day – resting on our gravel driveway.
Males have more angular forewings, and less rounded hind wings.
