Stem-borer: Larva feeding as internal stem-borer (Spencer, 1972b: 95, as Phytomyza cineracea).

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).

Elongate, slightly tapering, pale brown; posterior spiracles scarcely raised, each with an ellipse of 16-25 bulbs (Spencer, 1976: 342).
