Leaf-miner: The early gallery starts in the centre of the leaf. It is a
linear track which widens to a large blotch at the leaf edge, with
frass in long threads (British
leafminers).
Corridor,
generally beginning in the neighbourhood of the midrib, rather gradually
widening into a very large blotch. Frass in long threads. Pupation
in the ground (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).
Adult:
The adult is illustrated in UKMoths.
The species is included in mothdissection.co.uk.
