Leaf-mine: In autumn the larva makes a long, somewhat blistered, slightly transparent corridor. In spring it mines the basal leaves that lie on the ground. These mines are swollen, clouded green, opaque, and the mined tips of the leaves are puckered and shrunken,filled with frass (Bladmineerders van Europa).

Larva: Rather thick, light yellow; head light brown. See Steuer (1973a) for an illustration of the characteristic sclerites in the pronotum, prosternum, and anal shield (Bladmineerders van Europa).

Pupa: See Patocka (1999a) and Patocka and Turcani (2005a) (Bladmineerders van Europa).

Adult: Not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
