Specimens in nature


A large, oval, tentiform mine on the underside of a leaf, usually between two side veins; rather many longitudinal folds, which might be difficult to see because of the many hairs on the leaves; upperside puckered. The frass is concentrated in one corner of the mine. The mine of this species cannot be distinguished from that of Phyllonorycter hilarella.

A strong, golden-brownish cocoon inside the mine; pupa light brown to golden brown.
