    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.

They can be found mainly in the spring in oak woodlands, forests, parks, gardens,

    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
