and case-bearer: The larva feeds on the seeds and makes a case from the empty seedhead.
The presence of larvae can be seen by the holes they leave in the
in a floret that has been eaten out, and strengthened with silk.
Usually the larvae live in the inflorescence and feed upon the developing
fruits, but sometimes one strays to the leaves (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).
Described by Suire (1961a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The adult is illustrated in UKMoths. The male
genitalia are illustrated by the Lepidoptera Dissection Group.
