In Belgium the larva feeds at first between some needles of Larix
spun together. It has been observed also on Picea sitchensis.
After hibernation it feeds in the expanding buds. Pupation in
the larval feeding place (Belgian Lepidoptera).
late summer the larva spins a few needles together, and mines them
out. The larva hibernates between some mined needles that haven
been spun together. After hibernation the larva bores into a developing
bud, eventually pupating there (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 Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
See Patocka and Turcáni (2005a) (Bladmineerders van Europa).
The adult is illustrated in UKMoths.
and female genitalia are illustrated by the Lepidoptera Dissection Group.
