Leaf-miner: Mines the lower leaves, making them hollow. The mine is along the
midrib and broadens into a blotch (British
or several broad corridors, radiating from the leaf base, often
along the midrib, towards the leaf tip widening into a roundish
blotch, not containng any frass. The larva, that seems to feed only
at night, retreats during feeding pauses in the leaf base and is
invisible then. Often two larvae in a mine. Pupation in a little
separate mine (pupal chamber) (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 yellow to greenish, head pale brown (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 genitalia are not illustrated by the Lepidoptera Dissection
Group (check for update).
