Leaf-miner: A chestnut brown blotch on upper side of leaf, frass in concentric
arcs (British
leafminers).
Brick
red, upper-surface blotch, not preceded by a corridor. Almost all
frass is ejected through a slit in the upper epidermis, at the margin
of the mine. Characteristic is a pattern of fine concentric lines
around the site of oviposition. Rather soon the larva begins to
make a flat saucer-shaped cocoon. During feeding pauses it rests
here in a horse-shoe position (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 yellow 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).
Adult:
The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.
