Gypsonoma dealbana (Frölich, 1828)
[Lepidoptera: Tortricidae]

Common Cloaked Shoot

Tortrix dealbana Frölich, 1828. Enum. Torts. Württ.: 51
Gypsonoma dealbana
(Frölich, 1828).

Leaf-miner: The larvae feed on a range of deciduous trees, windowing leaves in autumn and eating the buds, catkins, young shoots and then spun leaves in the spring (UKMoths). The mine is illustrated in 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).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Cocoon formed in soil or where the larva fed British leafminers.

Adult: The adult is illustrated in UKMoths and the Encyclopedia of Life. The species is included in
