Stem-mine: A long external whitish stem mine, feeding downwards from a leaf stalk or part of the upper stem. Pupation external (Spencer, 1972b: 41).

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).

Yellowish (Spencer, 1972b: 41).

Comments: Only a single female has been reared (Spencer, 1990: 127).
