A narrow, whitish linear mine. Pupation internal (Spencer,
less often lower-surface corridor. Frass in isolated grains. Puparium
within the mine, usually at the lower surface (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.
Posterior spiracles with 6-9 bulbs (Bladmineerders van Europa).
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).
