Extensive mining may destroy entire leaves. Full-grown larvae pupate in silken, spherical cocoons in larval mines. May. They feed primarily on the undersurface of leaves, as did parent adults, but may also feed on the upper surface. Typically, new weevils feed in groups, with feeding commonly beginning at leaf margins in the apical portion of the leaf. Feeding by new-brood adults may be extensive, and damage to foliage may be severe.
Adults move to trash and duff near host trees and remain inactive until the following spring.
Only one generation occurs each year. Order Coleoptera, Family Curculionidae. No standardized common name has been established for O. calceatus .
