Caryocolum blandella
(Douglas, 1852).


Leaf-miner: The larva feeds at first in a mine, then in spun shoots or seed capsules (UKMoths).

Long narrow gallery close to the midrib. Older larvae live free among spun leaves or inflorescence (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 illustrated in UKMoths. Body and thoracic legs yellowish green; head and prothoracic plate black (Bland et al., 2002a) (Bladmineerders van Europa).

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

Adult: The adult is illustrated in UKMoths by Jack Astley. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
