The wingspan is 11.5–16 mm. The forewings are covered with white-tipped dark scales, the darker color fuscous at the base, becoming black at the apex. The forewings are marked with narrow longitudinal streaks of white-tipped golden scales, one below the costa, one along the fold, and a third midway between the two, rather distinct on the basal half, the streaks beyond the middle becoming shorter, more numerous, and confused, forming a rather distinct V-shaped area of golden scales pointing toward the apex just before a strong edging of white-tipped black scales. The hindwings are dark silvery fuscous.[3] Adults are on wing from May to August.[4]
The larvae feed on Rudbeckia maxima. They feed on the flowerhead of the host plant and pupate within the burrow or in the upper part of the stem.
