Clouded Sulphur Colias philodice	Upper surface of male wings bright, clear yellow with solid black edging; lower side of forewing with some dark submarginal spots; hindwing with silver cell spot rimmed with orange-pink, usually doubled. Female has 2 forms: yellow form with uneven black edging enclosing yellow spots, and a white form which is greenish-white rather than yellow. Spring and fall forms are smaller and less conspicuously marked.
Monarch Danaus plexippus	Upperside of male is bright orange with wide black borders and black veins; hindwing has a patch of scent scales. Upperside of female is orange-brown with wide black borders and blurred black veins. Both sexes have white spots on borders and apex. The Viceroy butterfly (Limenitis archippus) is a Mullerian mimic; it has similar coloration and is also distasteful.
Orange Sulphur Colias eurytheme	Quite variable. Upperside of male yellow with orange overlay, yellow veins, wide black border, and dark black cell spot. Female yellow or white with irregular black border surrounding light spots. Underside hindwing spot silver with 2 concentric dark rings, and a spot above it.
Pearl Crescent Phyciodes tharos	Quite variable. Males usually have black antennal knobs. Upperside is orange with black borders; postmedian and submarginal areas are crossed by fine black marks. Underside of hindwing has a dark marginal patch containing a light-colored crescent. Spring and fall broods (form marcia) have a gray mottled hindwing below.
American Copper Lycaena phlaeas	Upper surface of forewing shiny, fiery orange-red with black spots; hindwing gray with orange-red outer margin. Underside gray; hindwing with submarginal row of orange-red zigzags.
American Lady Vanessa virginiensis	Upperside with uneven brown, yellow, and orange pattern. Forewing with a black apical patch, a small white spot in the orange field below the patch, and a white bar at the leading edge of the forewing. Underside of hindwing with two large eyespots. Winter form is smaller and paler, summer form larger with brighter coloring.
Spring Azure Celastrina ladon	Seasonally variable and sexually dimorphic. Upperside of males blue, females with some black at outer edge of forewing. Late spring and summer forms with white above. Underside hindwing gray-white with faded small black dots, darker gray with larger black spots, or with blotches and black margins in the center.
Eastern Tailed-Blue Cupido comyntas	One narrow tail on hindwing. Upperside of male iridescent blue; summer females uniformly brown, spring females smaller with much blue at the wing bases. Underside of hindwing pale gray with black bar at end of cell, distinct black spots, and three large orange spots at outer margin near tail.
