Leaf-miner: The larva feeds in a blotch on the underside of the leaf, which
contracts and causes the leaf to pucker strongly. The mine is quite
large and can occupy most of a leaf (UKMoths).
Lower-surface
tentiform mine, that in small leaves can occupy the entire underside.
The mine does contract strongly, folding the leaf, sometimes causing
it to become tube-like. Lower epidermis with many fine folds. Frass
packed in the opposite corner (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).
The yellow 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).
The pupa is illustrated in British
leafminers.
Adult:
The adult is illustrated in UKMoths.
The species is included in mothdissection.co.uk.
