Stem-borer: Internal stem-borer. Pupation internal (Spencer, 1972b: 20)

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.

The larva is described by Dempewolf (2001: 86).

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).

Whitish grey; posterior spiracles adjoining, each process with 16-22 bulbs around the strong central horn (Spencer, 1972b: 20).
