Leaf-mine: Details of mine unknown (Bladmineerders van Europa). Pupation external (Spencer, 1972b: 52).

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).

Posterior spiracles each with 6-8 bulbs (Spencer, 1976: 262).
