Leaf-miner:
The larva mines the leaves, forming brownish or whitish inflated
blotches (UKMoths).
Whitish
or brownish full depth blotch, preceded by a short corridor that
originates on the midrib or in the leaf base. Frass grains irregularly
dispersed; part of the frass is ejected from the mine. The larva
makes several mines. Pupation outside the mine (Bladmineerders van Europa).
The
mine is also described 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).
Uniformly yellowish green (dorsally a somewhat darker length line) with light brown head (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.
