Leaf-miner: Makes an elongate mine with frass heaped at the start and then dispersed
thoughout. It does not make a silken shelter and so may be seen
in the mine (British
leafminers).
At
first a gallery, but soon widened to a broad blotch, entirely or
partly running upwards, in the end half as wide as the leaf. The
mine is widened without consideration for the length veins, making
the mine less sharply delineated than in C.
scribaiella. Most frass in the first section, but higher
up still some scattered frass visible. Unlike C.
scribaiella the larva does not spin a shelter for retreat
in the mine; this makes the larva easily visible in the unopened
mine. Cocoon in the top section of the mine. The pupa lies head-upwards,
just below an opening that has been prepared as an exit for the
later moth (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 by Alan Drewitt. The species is included in mothdissection.co.uk.
