Leaf-miner: A gallery which leads to blotch (no slit in lower epidermis so the
frass accumulates in the blotch) (British
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).
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
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).
The adult is illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera
