Leaf-miner: The frass linear in early gallery, widening to blotch with dispersed
frass (British
leafminers).
Oviposition
at random point of the leaf, either at upper- or lower-surface.
First a quite slender corridor is made, with a relatively broad,
continuous, frass line, that always leaves a clear margin at either
side; the corridor winds freely through the leaf. This initial corridor
often abruptly changes in direction, widens into a blotch that mostly
lie along the leaf margin. 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 whitish (British
leafminers).
Described
by Gustafsson and van Nieukerken (1990a) (Bladmineerders van Europa).
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.
The species is included in mothdissection.co.uk.
