Leaf-miner
and case-bearer: Larva mines leaves, forming a case from an excised mine. This case
is later extended, and widened by slitting the ventral side to insert
a gusset. The full-grown case is 8 mm long with a single ventral
keel (British
leafminers).
Full
grown larva in a slender greyish white three-valved tubular silken
case of c. 8 mm; mouth angle about 45°. Often several cases
together on a small number of plants (Bladmineerders van Europa).
The
case and feeding holes are illustrated in the Encyclopedia of Life.
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).
Described by Emmet, et al. (1996a) (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.
