Normal host is American Basswood (Tilia americana, Tiliaceae), but has been reported from plants of seven other families, incl. Fagaceae, Salicaceae, and Rosaceae (6). New Mexico and Utah records both on Quercus gambelii, according to Cameron Ramsey.

Overwinter as adults under leaves and debris. Eggs are deposited singly at the edges of skeletonized areas on these leaves about mid-June. The larvae feed by mining the leaves. There is 1 generation of miners per year.(1)
