Leaf-miner and case-bearer: Tubular leaf case. The case is almost barrel-shaped, with a large leaf fragment that, while withering, folds itself untidily arround the tube (Bladmineerders van Europa).

A biennial life cycle in the UK (may be annual in Europe). The second and third cases are formed by cutting out a large leaf portion and then wrapping it around - leaving an edge protruding, which then withers (British leafminers).

Larva: Only three pairs of abdominal prolegs (Emmet et al., 1996a) (Bladmineerders van Europa).

Pupa: Details unknown.

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