Lifestyle: Currently 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: Spencer (1990) deduced from the distinctive genitalia that infuscata is a grass-feeder.

Hosts in Great Britain & Ireland: Currently unknown.

Hosts elsewhere: Currently unknown.

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain & Ireland: Rare. Records include Cambridge (Chippenham Fen) (Spencer, 1972b: 50, as portentosa), Dunbarton (Bonhill) (Bland, 1994c: 82) and Huntingdonshire (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including Denmark, Sweden, Finland, Germany (Spencer, 1976: 254), Belgium, Czech Republic, French mainland, Latvia, Lithuania, Poland, Slovakia and Spanish mainland (Martinez in Fauna Europaea).
