Leaf-miner: A narrow contorted gallery leading to a whitish blotch with scattered frass centrally. The early gallery can merge with the blotch and there are often several to a leaf (British leafminers).

The larva begins by making a full depth corridor, erratic in width and course; frass black, in an irregular central line. Later the larva makes a blotch, with frass in irregular clouds. This blotch can be a continuation of the corridor, but may just as well be on a different leaf. Often several mines in a leaf; in such cases the entire leaf me be mined out. Mines white at first, turning brown later. The larva lies venter-upwards in the mine. Pupation external Bladmineerders van Europa).

The mine is also illustrated in UKMoths.

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 is light yellow, with darker thoracic legs (British leafminers). The larva is also illustrated in Bladmineerders van Europa.

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

Occasionally in a mined leaf or in a cocoon between the leaves or on the leaves (British leafminers).

Adult: The adult is illustrated in UKMoths and the Encyclopedia of Life. The female genitalia, but not the male genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
