Leaf-miner: A long sinuous mine, frass variable, which often follows leaf-edge
at the upperside of the leaf. The mine is a long, gradually widening
corridor that often closely follows the leaf margin for a long distance.
Frass at first in a broad central line, but soon it becomes coiled.
Occasionally mines occur with linear frass throughout; such mines
can be distinguished from those of Stigmella
magdalenae because they are broader and less confined the
a small space (Bladmineerders van Europa).
mine is also illustrated in UKMoths.
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 green, head pale brown (British
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).
The adult is illustrated in UKMoths. The genitalia are not illustrated by the Lepidoptera
Dissection Group (check for update).
