Leaf-miner: Forms a large transparent blotch mine - with a central spot, where
the frass collects. This spot is usually red-brown (British
leafminers).
Brownish,
full depth, inflated blotch, usually at the leaf margin, often with
a central brown spot. Oviposition at the leaf underside. Often 2-3
larvae in a mine. Pupation outside 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 on the bark in a cocoon (British
leafminers).
