Leaf-mine: Details unknown (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 and Ireland: Currently unknown.

Hosts elsewhere:

Poa chaixii Broad-leaved Meadow-grass   Bladmineerders van Europa
Poa chaixii Broad-leaved Meadow-grass   Spencer, 1990: 355
Poa chaixii Broad-leaved Meadow-grass   Scheirs, de Bruyn and von Tschirnhaus, 1995

Time of year - mines: Currently unknown.

Time of year - adults: July.

Distribution in Great Britain and Ireland: Buckinghamshire (Aylesbury) (Spencer, 1972b: 100).

Distribution elsewhere: Widespread in continental Europe including Denmark, Finland, Norway, Sweden, Austria (Spencer, 1976: 222), Germany (Spencer, 1990: 373), Belgium (Bladmineerders van Europa ; Scheirs, de Bruyn and von Tschirnhaus, 1995), Czech Republic, Estonia, French mainland, Hungary, Latvia, Lithuania, Poland, Slovakia and ? Yugoslavia (Fauna Europaea).
