Monoptilota is a genus of snout moths. It was described by Hulst in 1900. It contains only one species, the Lima-bean Vine Borer Moth (Monoptilota pergratialis), which is found in the central and south-eastern parts of the United States. The wingspan is 21–23 mm. Adults are brownish-grey with whitish scales on the edge and across the end of the forewings. These are marked with small black streaks and are black along the veins. The hindwings of the males are white, while those of the females are greyish. There are three generations per year in North Carolina.
