Leaf-miner
and case-bearer: Tubular leaf case. The case is almost barrel-shaped, with a large
leaf fragment that, while withering, folds itself untidily arround
the tube (Bladmineerders van Europa).
A
biennial life cycle in the UK (may be annual in Europe). The second
and third cases are formed by cutting out a large leaf portion and
then wrapping it around - leaving an edge protruding, which then
withers (British
leafminers).
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).
Only three pairs of abdominal prolegs (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.
