Leaf-mine: A narrow, upper surface winding linear mine, brown when old. Pupation external (Spencer, 1976: 313 (fig. 563), 314).

A hardly widening corridor from beginning to end, yellow green in colour. The start is lower-surface, but after some time the mine becomes upper-surface. Part of the frass in thread fragments. Pupation outside the mine; exit slit in upper epidermis (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).

Reddish; posterior spiracles each with up to 20 bulbs in two rows (Spencer, 1976: 314).
