Lifestyle: Unknown.

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).

Comments: The larvae are almost certainly not leaf-miners but probably feed internally either in stems of flower-heads (Spencer, 1972b: 61).

Hosts in Great Britain & Ireland: Currently unknown.

Hosts elsewhere: Currently unknown.

Time of year - larvae: Currently unknown.

Time of year - adults: June, August.

Distribution in Great Britain & Ireland: Uncommon. Stafford (Madeley), Brecknock (Cusop) (Spencer, 1972b: 61); Radnorshire (NBN Gateway).
