Stem-miner: The
eggs are laid in the stem in the current year's growth and the whitish
mine progresses up the stem terminating at the base of the leaf.
The larva curls over the leaf edge to pupate (Langmaid
& Corley, 2007).
Oviposition
on a young twig. From there a long corridor is made in the bark,
up to 30 cm in length, running up or down, hardly widening. Finally
the corridor enters a petiole and a leaf where, close to the base,
at the upperside, a white cocoon is spun in which pupation takes
place (Bladmineerders van Europa).
The
mine is also illustrated in British
leafminers.
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).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Black (Bladmineerders van Europa).
