Leaf-mine: A small mine (about 1cm long), which strongly arches the leaf. The mine of Parornix betulae can appear similar, but the underside becomes brown whereas the mine of P. anderidae stays green (British leafminers).

Small lower-surface tentiform mine; epidermis pale green, rather weakly folded. The pupa lies without a cocoon in the mine (Bladmineerders van Europa).

Larva: Details unknown.

Pupa: The cremaster is illustrated in British leafminers and Bladmineerders van Europa.
