Leaf-miner: The gallery is long and broad, frass dispersed in later part
of mine (British
leafminers).
Oviposition
on the leaf underside, almost always close to a thick vein. Mine
a fairly long, rather slender corridor. Frass in a broad, often
interrupted central band; locally it may be in coiled (Bladmineerders van Europa).
It is recommended that you try to rear out the adults to be certain of their identity.
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 British
leafminers and 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 by Rob Edmunds.
The species is included in mothdissection.co.uk.
