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).

Hosts in Great Britain & Ireland: Currently unknown.

Hosts elsewhere: Unconfirmed but probably Carex (Spencer, 1990: 349).

Time of year - larvae: August.

Time of year - adults: Currently unknown.

Comments: Cerodontha scutellaris (von Roser, 1840) is treated as a synonym of Cerodontha scirpi (Karl, 1926) in Bladmineerders van Europa.

Distribution in Great Britain & Ireland: Added to British checklist by Cole (in Chandler, 1998: 137).

Also recorded in the Republic of Ireland (Martinez in Fauna Europaea).
