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.

The larva is described by Dempewolf (2001: 123).

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:

Dactylis glomerata Cock's-foot British Wild Flowers by John Somerville et al. Dempewolf, 2001: 123

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Widespread in southern England (Spencer, 1976: 183); Cambridgeshire, East Kent, Elgin and South-west Yorkshire (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including Denmark, Finland, Poland, Estonia, Austria, Switzerland (Spencer, 1976: 183), Germany (Dempewolf, 2001: 123), Czech Republic, French mainland, Hungary, Latvia, Lithuania, Norwegian mainland, Slovakia and Switzerland (Fauna Europaea).
