Habitat: Dry to moist fields, wet meadows, and wood edges. Easily attracted to gardens with flowers such as Butterfly Bush, milkweeds, and Purple Coneflower.

Flight Period: Two to three broods, that result in a fairly even distribution from mid April to mid-October without obvious peaks. Extreme dates: North Jersey 4/14—10/28; South Jersey 3/19—11/2.

Larval Food Plants: Primarily Black Locust (Robinia pseudoacacia), but also many other legumes, such as tick-trefoils (Desmodium). Larvae bind leaves together to form shelters.

Overwintering Stage: Pupa.

Best Locations: Just about anywhere near the host plants.

Comments: This is one of most familiar butterflies of NJ gardens. The large white spot on the underside of the hindwing appears to glow and can be seen even while this energetic butterfly zooms around.
