The Ash Leaf Cone Roller Moth (Caloptilia fraxinella) is a moth of the Gracillariidae family. It is known from Canada (Québec, Alberta, Ontario and Saskatchewan) and the United States (Michigan, Vermont, Ohio, Connecticut, New York and Maine).It is considered a significant pest of horticultural ash.The larvae feed on Fraxinus species (including Fraxinus americana, Fraxinus mandshurica, Fraxinus nigra and Fraxinus pennsylvanica) and Ligustrum species. They mine the leaves of their host plant. The larvae form a typical leaf cone. The species is atypical for the Caloptilia genus in that the larva pupates within the leaf cone, in a suspended silken cocoon. The species overwinters as an adult.
