Leaf-miner and case-bearer: Lobe case. Many small leaf fragments are attached to the tubular case; its end is strongly curved downwards. The larvae are attached to the leaf underside, where they make a large number of relatively small full depth mines (Bladmineerders van Europa).

Only one case is formed and this is coated in leaf fragments (as shown). The final case is strongly curved and about 5mm long (British leafminers).

Larva: The larva is illustrated in Bladmineerders van Europa.

Pupa: Details unknown.

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