Leaf-mine: The mine is long, frass linear (British leafminers).

Egg at the underside of the leaf, close to a vein. The mine is a very long and slender gallery, hardly widening at all. Frass in a continuous, very narrow central line. The corridor follows veins over long distances, obtaining thereby an angular appearance (Bladmineerders van Europa).

Larva: The larva is a greenish white, head brown (British leafminers). The larva is illustrated in Bladmineerders van Europa.

Pupa: Details unknown.

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