The old literature indicates that P. oleracea was a crop pest in eastern
Canda until it was displaced by the Cabbage White. The type specimens of P.
oleracea were collected on crops as larvae. So European colonization
probably greatly increased the abundance of P. oleracea, and then Cabbage
Whites displaced them from cultivated areas.
