Stem borer: Larva an internal stem-borer. Pupation internal (Spencer, 1972b: 19).

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).

Puparium pale, straw-coloured. Posterior spiracular processes black, separated approxiamately by own diameter, each with 14-18 bulbs around a black central horn (Spencer, 1972b: 19).
