Leaf-mine: Larva and puparium in the leaf sheath; otherwise undescribed (Bladmineerders van Europa).

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, but certainly Poaceae [as Gramineae] (Spencer, 1972b: 106).

Hosts elsewhere:

Poaceae        
Poa nemoralis Wood Meadow-grass   Bladmineerders van Europa
Poa nemoralis Wood Meadow-grass   Scheirs, de Bruyn and von Tschirnhaus, 1995

Time of year - mines: June-July (Scheirs, de Bruyn and von Tschirnhaus, 1995).

Time of year - adults: July.

Distribution in Great Britain & Ireland: Widespread in Britain including Denbighshire (Cefn-y-bedd) (Spencer, 1972b); Cambridgeshire, East Kent, Easterness, Fife, Glamorgan, Isle of Wight, Monmouthshire, South-west Yorkshire, Stafford and West Norfolk (NBN Atlas).

Also recorded in the Republic of Ireland: Co. Clare (Spencer, 1972b: 106).

Distribution elsewhere: Widespread in much of Europe including Denmark, Finland, Sweden (Spencer, 1976: 181), The Netherlands (Bladmineerders van Europa), Belgium (Scheirs, de Bruyn and von Tschirnhaus, 1995), Germany (Spencer, 1976: 550), Austria, Czech Republic, Estonia, French mainland, Lithuania, Poland and Slovakia (Martinez in Fauna Europaea).

NBN Atlas links to known host species:

Poa nemoralis

British and Irish Parasitoids in Britain and elsewhere: Currently unknown.
