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.
