Leaf-miner: A contorted gallery with dispersed frass, leading to a blotch (British
at the underside of the leaf. The mine is a highly contorted gallery,
strongly widening towards the end. Frass in the second half of the
gallery dispersed. The larva mines venter upwards. Mostly several
mines in a leaf (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).
Larva greenish-white with green gut-line and brown head (British
