The Sugarbeet Crown Borer Moth[2] or Sugarbeet Crown Borer (Ancylosis undulatella) is a species of snout moths in the genus Ancylosis. It was described by Clemens in 1860.[1] It is found in North America, from Ontario and Michigan to Florida, west to California, north to Oregon and Idaho.[3]

The wingspan is 16-18 mm. The forewings are narrow, light brown to greyish-brown with a reddish-brown to black band in the basal area. The hindwings are more than twice as broad as the forewings and greyish-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]
