Leaf-miner: In a small Phyllonorycter-like mine initially, but with brown rather than green lower epidermis. Later in two or more successive cones formed by folding leaf-lobes downwards (British leafminers).

The mine begins at a flat, iridescent egg shell. It starts as an epidermal corridor, widening into (and mostly over run by) a shallow lower surface blotch in the tip of a leaf segment. The lower epidermis is off-grey with small light brown spots at first, but soon turns brown. Silk is deposited within the mine, causing it to contract. This wrinkles the lower epidermis, but there are no clear folds formed. Soon the larva starts consuming the palissade parenchyma, and the upperside of the mine than turns brown as well. Frass in loose grains. After some time the larva leaves its mine and continues living free under a downfolded leaf segment, kept in place by some spinning. Here too the leaf tissue is consumed up to the palissade parenchyma, browning the leaf (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 Bladmineerders van Europa.

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

In a folded leaf edge or on leaf-litter (British leafminers).

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