Stem-borer: Larva feeding internally in the stems. Pupation internal. (Spencer, 1976: 284). The larva bores in the pith of the thicker parts of the leaves, leaf sheets and flower stalk. The puparium is formed within the mine (Bladmineerders van Europa).

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.

Dark brown; each spiracular process on a separate projection and each with a regular ellipse of 12 well-defined bulbs (Spencer, 1976: 284). The larva is also described by Dempewolf (2001: 136).

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).
