Leaf-miner: Before overwintering larvae make a small, full depth blotch (Robbins, 1991a). After hibernation, they live freely under a silk. Larvae mine in late autumn (Agassiz, 1996a). Not rare, in Belgium (De Prins, 1998a) (Bladmineerders van Europa).

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).

The larva overwinters when small (UKMoths).

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

The pupa is illustrated in UKMoths.

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
