Stem-miner: External stem-miner (Spencer, 1972b: 61).

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).

Hosts in Great Britain and Ireland:

Asteraceae
Sonchus	oleraceus	Smooth Sow-thistle	Robbins, 1991: 125

Distribution in Great Britain and Ireland: Uncommon, but locally abundant including London (Cripplegate), Essex (Flatford) and Huntingdonshire (Woodwalton Fen) (Spencer, 1972b: 61); Glamorgan (NBN Atlas).
