Stem-borer: Larva boring in stem. Pupation internal (Spencer, 1972b: 17).

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).

Posterior spiracles separated by own diameter, each with 14-18 well defined bulbs around the central small horn (Spencer, 1972b: 15).

Hosts in Great Britain and Ireland:

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

Hosts elsewhere: Currently unknown.

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Kent (Faversham), Essex (Flatford and Mersea), Glamorgan (Llanridian salt marsh) (Spencer, 1972b: 36); Caernarvonshire, East Kent, North Essex and South-west Yorkshire (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including Czech Republic, Denmark, French mainland, Germany, Spanish mainland and The Netherlands (Fauna Europaea).
