Leaf-miner: The mine is a whitish blotch with scattered blackish frass (UKMoths),
usually low on the plant (British
on the basal part of the midrib. The young larva makes a number
of short corridors radiating from this point, either in the same
leaf, or on different ones; they have a central frassline, but their
final sections are free of frass. Later an elongate blotch is make,
also beginning on the midrib (although not necessarily its basal
part). Pupation external (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).

Greyish green; head and prothoracic plate black (Koster, 2002b;
Koster and Sinev, 2003a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupation in a white cocoon, which is attached to vegetation or leaf litter
leafminers). See also Patocka and Turcáni (2005a) (Bladmineerders van Europa).
The adult is illustrated in UKMoths
(by Jon Baker) and the Encyclopedia
of Life. The male
genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
