One of many Duskywings, the Juvenal's Duskywing is a larger yet more varied species that is commonly found in eastern and southwestern states.
A fast flier, Juvenal's Duskywing is hard to identify the moment its spotted. It resembles other Duskywings and a careful study of its color and pattern are needed to get a correct identification. One version looks a lot like Horace's Duskywing. Add to that, Juvenal's Duskywing individuals have variations in colors and pattern based on what region they are in. To make it even more complicated, males and females are different in color and pattern, too.
Males perch on plants low to the ground and scan for females. They may return to a familiar perch if frightened away. Adults drink nectar from dandelions as well as plum, blueberry, lilac, wisteria, and Carolina vetch blossoms. Caterpillars eat oak tree leaves. Two generations a year is typical in warmer south and southwestern states; one generation is the norm in cooler states. They can be found mainly in the spring in woodlands, forests, parks, and gardens that have at least a few oaks nearby.
