Stem-miner: An external stem mine. Pupation in the stem, near or even below ground level, with the anterior spiracles projecting through the epidermis (Spencer, 1976: 72-3).

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-brown; posterior spiracles widely separated, each having 17-22 bulbs (Spencer, 1972b: 21 (fig. 36), 25; Spencer, 1976: 72, 73 (fig. 90).
