Leaf-miner:
Feeding
is in leaf blotches, spun shoots and roots. Wilting greyish leaves,
or frass in the crown of the plant may indicate a larva in the roots
(UKMoths).
Young
larver make a short, very narrow gallery in the young leaves. Later
they bore in the rhizome (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).
Body yellowish white with several salmon length lines; head, prothoracic
plate and thoracic legs blackish brown; anal plate light brown (Bland
et al., 2002a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupae are found in the plant root from May to August (UKMoths).
See Patocka and Turcáni (2005a) (Bladmineerders van Europa).
Adult:
The adult is illustrated in UKMoths The species is included in mothdissection.co.uk.

Time
of year - larvae: Larvae are found from April to August. It
is uncertain if there is more than one generation, or just a single
protracted one (UKMoths).
