Leaf-miner: A circular or oval brownish blotch with a central spiral of dense
blackish frass (British
leafminers), sometimes several mines in one leaf (UKMoths).
Oviposition
is at the leaf underside, well away from the leaf margin; the egg
has a fine reticulate surface. The mine is a rather large, perfectly
circular blotch without a trace of a preceeding corridor. Around
the dark centre the frass, glued to the upper epidermis is arranged
in distinct arcs (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 pale green with a dark head (British
leafminers).
The
larva is also illustrated in UKMoths and Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupation in
a silken cocoon, usually on detritus (British
leafminers). Described by Patocka (2000a) (Bladmineerders van Europa) and illustrated in the Encyclopedia of Life.
Adult:
The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.

This
species can be rather erratic in its occurrence and can be quite
a difficult species to track down. In some years there is a population
explosion when it appears commonly, but in between can be quite
uncommon (UKMoths).

Austria, Belgium, Bulgaria, Croatia, Czech Republic, Danish mainland,
Estonia, European Turkey, Finland, French mainland, Germany, Greek
