Leaf-mine: Large full depth blotch in the lower leaves; much frass in coarse grains. The larva can make several mines. Pupation either in the mine or in the ground. Mines cannot be distinguished from those of Mompha lacteella (Bladmineerders van Europa).

Larva: Body brownish red; head black; prothoracic plate two dark brown rectangular sclerites; anal plate light brown, thoracic feet dark brown (Koster, 2002b; Koster and Sinev, 2003a) (Bladmineerders van Europa).

Pupa: Details unknown.

Adult: The adult is illustrated in UKMoths and the Encyclopedia of Life. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
