Stem-mine: A narrow, whitish external stem mine. Pupation external (Spencer, 1976: 312).

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 each have 3 bulbs (Spencer, 1976: 312).

Comments: Galium mollugo is treated as Galium album (Hedge Bedstraw) by Stace (2010).
