Leaf-miner: A slender gallery, leading to blotch (British
leafminers).
Egg
on the underside of the leaf. The first part of the mine is a long,
slender corridor, rather straight, often folllowing a vein or the
leaf margin. The frass here is black, lying in a very narrow central
line. The corridor abruptly widens into a large blotch, where the
the frass lies irregularly scattered (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).
Pale greenish yellow. See Gustafsson and van Nieukerken (1990a)
for an extensive description (Bladmineerders van Europa).
