Leaf-miner: A gallery, with coiled frass in central part (British leafminers).

Oviposition generally at the upperside of the leaf, and not far from the leaf margin. The mine is a rather wide corridor, that often crosses a vein, and almost invariably runs from somewhere near the leaf margin in the direction of the midrib. Its first part is quite narrow, with a narrow central frass line. The next section is wider, and here the frass is distinctly coiled. In the final section the frass lies somewhat more irregular, and in a rather narrow central zone (Bladmineerders van Europa).

The mine is also illustrated in the Encyclopedia of Life.

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 whitish-yellow, head pale brown (British leafminers).

Described by Gustafsson and van Nieukerken (1990a) (Bladmineerders van Europa). See also NBDC interactive map.

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 and the Encyclopedia of Life. The male genitalia, but not he female genitalia (check for update) are illustrated by the Lepidoptera Dissection Group.
