Caryocolum junctella (Douglas, 1851)
[Lepidoptera: Gelechiidae]

Confluent Groundling


Gelechia junctella Douglas, 1851. Trans. ent. Soc. Lond. 2 (1): 103.
Caryocolum junctella
(Douglas, 1851).


Leaf-miner: Young larvae make mines, but the mines have not been described. Older larvae live among the tips of the shoots, that are spun together (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 described by Bland et al., 2002a).

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. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
