Leaf-miner and case-bearer: Larva in a huge (19 mm) shining black tubular silken case; mouth angle 60°. The end of the case is strongly rolled in (remnant of the youth case) and bears a small pallium (Bladmineerders van Europa).

The final case is the largest of any coleophorid in the UK, being 19mm long. The anal end of this case incorporates the remains of the spiral first case and is hooded in a pallium (British leafminers).

Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).

Described in detail by Emmet at al. (1996a) (Bladmineerders van Europa).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Adult: The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.

Comments: A very rare and declining species, known from a very few sites in the UK. (British leafminers).
