Stem-mine: An external stem mine. Frass is deposited at wide intervals. Pupation in the mine (Spencer, 1972b: 27; Spencer, 1976: 76).

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.

Posterior spiracles each bearing numerous (up to 28) bulbs, on three arms (Spencer, 1976: 76 (fig. 100)).

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).

Black; posterior spiracles each bearing numerous (up to 28) bulbs, on three arms (Spencer, 1972b: 27).
