Cameraria walsinghami is a moth of the Gracillariidae family. It is known from California, United States. The length of the forewings is 4.5-5.5 mm. The larvae feed on Lithocarpus densiflorus var. echinoides. They mine the leaves of their host plant. The mine is oblong and the epidermis is opaque yellow tan. The mines are usually found on both sides of the midrib or, rarely, to one side of the midrib on larger leaves. The mines are always solitary, with one or two short longitudinal folds, always at the edge of the leaf.
