Leaf-miner: A gallery which leads to blotch (no slit in lower epidermis so the
frass accumulates in the blotch) (British
leafminers).
Oviposition
on the upperside of the leaf, next to a vein. The mine begins as
a narrow corridor with a broad frass line, running along a vein.
Generally the corridor runs along the midrib, or along a lateral
vein. In the latter case the direction usually is towards the midrib.
The corridor abruptly widens into a blotch, containing much frass,
laying against the midrib. Pupation external (Bladmineerders van Europa).
The
mione is also illustrated in the Encyclopedia of Life.
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).
Greenish or yellowish white, head and pronotal plate reddish-brown.
The head is dark brown (British
leafminers).
Translucent white with a dark brown head; no ventral plates. See Gustafsson and van Nieukerken (1990a) for a description (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.
