Leaf-mine: Mines the lower leaves, making them hollow. The mine is along the midrib and broadens into a blotch (British leafminers).

One or several broad corridors, radiating from the leaf base, often along the midrib, towards the leaf tip widening into a roundish blotch, not containng any frass. The larva, that seems to feed only at night, retreats during feeding pauses in the leaf base and is invisible then. Often two larvae in a mine. Pupation in a little separate mine (pupal chamber) (Bladmineerders van Europa).

Larva: Pale yellow to greenish, head pale brown (Bladmineerders van Europa).

Pupa: Details unknown.

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