Adults and larvae of the yellow-poplar weevil damage buds and leaves of yellow-poplar, magnolia, and sassafras.
Adults feed on expanding buds in April and May and later feed on the leaves, making rice-shaped holes. Eggs are deposited in the midribs of the undersides of leaves during May and early June. The larvae mine the leaves and later pupate within the mines. The adults then emerge and feed on the leaves until about mid-July, when they enter the duff and hibernate until the following spring. There is one generation per year.
