Leaf-miner: The larvae feed by mining the leaves forming a contorted gallery
(UKMoths).
A
strongly contorted, often intestinine-like corridor, often forming
a secondary blotch. Much green frass in broad arcs. Full grown larva
mostly on top of the midrib. Pupation external (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 red and white larva is illustrated in British
leafminers, UKMoths
and Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
On the ground in detritus (British
leafminers).
Adult:
The adult is illustrated in UKMoths by Nigel Whinney. The species is included in mothdissection.co.uk.
