Only the very youngest larvae make mines, and it is not well known
how these look like: probably small full depth mines. The older
larva make a tunnel of silk on a twig, mixed with frass and leaf
fragments, and feeds from there on the leaves. (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 dull reddish with intersegmental zones greenish; head
brown, prothoracic and anal plates black; pinacula small, black
(Bland et al., 2002a) (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 by Paul Brooks. The genitalia are not illustrated by the Lepidoptera
Dissection Group (check for update).
