Clavigesta purdeyi (Durrant, 1911)
[Lepidoptera: Tortricidae]

Pine Leaf-mining Moth


Rhyacionia purdeyi Durrant, 1911. Ent. mon. Mag. 47: 252.
Clavigesta purdeyi
(Durrant, 1911).


Leaf-miner: The larvae feed internally on the needles, overwintering in this stage (UKMoths).

The mine begins in the tip of a needle, and descends towards the base. The larva hibernates in its first needle. After hibernation the larva bores through the bud scales into the base of young needles, causing them to drop. Pupation outside the mine (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).

Reddish brown, c. 5 mm (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 illustrated in UKMoths and the Encyclopedia of Life. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
