Leaf-miner: The larva mines in the petiole, from where it makes corridors fanning
out in the blade. The corridors are parallel-sided, little branched
and almost full-depth. In fresh mine primary feeding lines are visible.
Pupation outside the mine (Bladmineerders van Europa).
Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.
Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).
