Southern and coastal butterflies are larger and have a yellow or yellow-orange patch on the outer part of the forewing. Inland butterflies are smaller and have the yellow forewing patch reduced or absent.
Southern Canada and the continental United States except for most of the Southwest and Texas, southern peninsular Florida, and northern Maine.
