During the past decade, this weevil has become very numerous in the Champlain Valley. Extensive feeding damage and high populations have been reported from West Haven and Cornwall. It is clothed with hairs. The larva is a typical cream-colored legless 5 to 7mm long weevil larva. The naked pupae is in an earthen cell in the soil.
Young adults are lighter brown and darken to deep brown-black with age.
The adult straddles the leaf edge and chews a semicircle out of the leaf margin. It continues to enlarge this semicircle before moving to another spot. Veins are not attacked and younger leaves are preferred. Scar tissue forms, resulting in a fork the following spring. The adult is diurnal in its feeding.
