Leaf-miner:
The larva initially mines a leaf of Common sorrel (Rumex acetosa)
in July and August, and then feeds externally on lower leaves until
May, when it pupates in a cocoon near the ground among vegetation
(UKMoths).
Young
larvae make a number of rather large, untidy full depth mines. The mines contain little or no frass. The lower-surface opening, by
which the larva has entered the mine, is irregularly roundish. Older
larvae live free on the plant (Bladmineerders van Europa).
The mine is 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).
See Tremewan (1985a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupates in a cocoon near the ground (Belgian Lepidoptera). Described by Patočka and Turčáni (2005a) (Bladmineerders van Europa).
Adult:
The adult is illustrated in UKMoths (by
David Painter) and the Encyclopedia
of Life. The species is included in mothdissection.co.uk.
