The larva feeds at first in a mine, then in spun shoots or seed
narrow gallery close to the midrib. Older larvae live free among
spun leaves or inflorescence (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 is illustrated in UKMoths.
Body and thoracic legs yellowish green; head and prothoracic plate
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 pupa is illustrated in UKMoths.
The adult is illustrated in UKMoths by Jack Astley. The male
and female genitalia are illustrated by the Lepidoptera Dissection Group.
