Stem-borer: Larva feeding as an internal stem-borer (Spencer, 1972b: 68).

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 & Ireland:

Asteraceae        
Aster tripolium Sea Aster British Wild Flowers by John Somerville et al. Spencer, 1972b: 111

Hosts elsewhere:

Asteraceae        
Aster       Spencer, 1990: 274

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain & Ireland: Probably widespread on salt marshes including Kent (Faversham) (Spencer, 1972b: 68); Glamorgan (NBN Gateway).

Also recorded in the Republic of Ireland (Martinez in Fauna Europaea).
