Leaf-miner: A whitish blotch on upper side of leaf. As the mine ages it can become a very pale brown colour (British leafminers).

Milky white upper-surface primary blotch, sometimes with an orange hue; no trace of a preceding corridor. The inside is lined with much silk, but the mine remains completely flat. The larva soon starts making of a discoid cocoon, about in the centre of the mine. When not feeding it rests in a horshoe-like posture in its cocoon. The mine contains practically no frass, which is removed through a cut in the upper epidermis near the margin of the mine. Pupation within the mine (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 is illustrated in British leafminers and Bladmineerders van Europa.

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

Pupation takes place in the mine, inside a circular chamber (UKMoths). The pupa is illustrated in Bladmineerders van Europa.

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