Leaf-miner: Larva initially feeding in a gallery which turns to a blotch and
finally one or more conical folds are made (UKMoths).
The
mine begins as an, occasionally quite long, lower-surface epidermal
corridor. Its last section is widened into a blotch. Only then the
larva begins to consume parenchymatous tissue and to line the inside
of the mine with silk. The upper surface of the mine turns orange
brown, and the leaf folds itself around the mine. Frass in a clump
in a corner of the mine. In the end the larva leaves its mine, and
then lives free in a leaf tip that has been folded downwards (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.

Hosts
elsewhere:
Time
of year - larvae: June; September-October (British
leafminers).
Time
of year - adults: There are two generations, moths being on
the wing in May and August. The flight time is evening onwards,
and sometimes it can be attracted to light (UKMoths).
