The wingspan is 16–18 mm. The forewings are narrow, light brown to grayish brown with a reddish-brown to black band in the basal area. The hindwings are more than twice as broad as the forewings and grayish brown with darker shading toward the outer margin. Adults are on wing from spring to fall in two generations per year.[3]

The larvae feed on the leaves, leafstems and crowns of sugarbeets. The species overwinters in the pupal stage in the soil.[3]
