Leaf-miner
and case-bearer: Tubular silken case of only 5-6 mm. The case
is weakly constricted near the anal end, and strongly just behind
the mouth. The case is sharply bent there; therefore the mouth angle
is 0° and the case lies adpressed to the leaf. The fully developed
case normally is trivalved. Larvae at the underside of the 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).
Described by Emmet et al. (1996a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Adult:
The adult is not illustrated in UKMoths (check for update). The species is included in mothdissection.co.uk.
