A deep pink line above yellow fringe makes this moth easier to distinguish from look-a-likes.
Yellow-fringed Dolichomia is a purple moth with two yellow, triangular marks on the outer edge of each forewing. A thin yellow line running across the wings connects the left and right marks at the base of the triangle. There are a couple of other moths with similar markings and coloration, but this species also has a dark pink-purple line along the bottom edges of the wings. A hairy, yellow fringe extends beyond it. It looks a lot like the Pink-fringed Dolichomia and the Clover Hayworm Moth.
The caterpillars of the Yellow-fringed Dolichomia feed on oak leaves. Adults are drawn to lights, and are most active from spring through autumn, though they extend activity in warmer southern states.
