Leaf-miner: The first generation gallery is short, the second generation is
longer. The frass is in a narrow line (British
leafminers).
Egg
at he upper- or underside. The mine is a long, slender, not very
contorted corridor. In the first part the frass lies in a very narrow
line; later the frass may in rare cases lie more widely scattered,
but nowhere does it take more than 1/3 of the width of the gallery
(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 whitish-yellow, head pale brown (this distinguishes
it from S. atricapitella which has a dark head) (British
leafminers).
Yellow,
head light brown (Huisman et al., 2001; Johansson et al., 1990a).
The light coloured head distinguishes the larva from the one of
atricapitella (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 by Rob Edmunds.
