Leaf-miner: Feeds initially in an underside epidermal mine then folds the leaf down (British leafminers).

The larva first makes a distinctly folded lower-surface tentiform mine. After some time the mine is vacated and the larva lives free then in a leaf margin that has been folded downwards and is secured with silk. In small leaves the two halves are simply spun together in a pod. Two of these leaf folds are made and eaten out. The folds with the free living larva strongly resembly the work of a sawfly larva on the same plant; however, then no silk is used to anchor the leaf margin (Bland, 1993a) (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).

See Bland (1993a).

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

See Patocka and Turcáni (2005a).

Adult: The adult is not illustrated in UKMoths (check for update). The species is included in mothdissection.co.uk.
