Lifestyle: Unknown, probably a stem-borer.

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: Currently unknown.

Hosts elsewhere: Currently unknown.

Time of year - larvae: Currently unknown.

Time of year - adults: July.

Distribution in Great Britain and Ireland: Britain including Kent (Dartford and Tunbridge Wells), Hertfordshire (Felden), Oxford (Hill Copse, Hogley, Yarnton), Dunbartonshire (Bonhill) (Spencer, 1972b: 44); Glamorgan, Montgomeryshire and Stafford (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including Austria, Germany, The Netherlands and Denmark (Spencer, 1976: 155), French mainland, Italian mainland, Spanish mainland (Fauna Europaea).
