Leaf-mine: Details 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 and Ireland: Currently unknown.

Hosts elsewhere:

Sesleria       Spencer, 1990: 356
Trisetum       Spencer, 1990: 355

Time of year - mines: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Added to British checklist by Henshaw in Chandler, 1998.

Distribution elsewhere: Widespread in continental Europe including Finland, Norway, Sweden, [former] U.S.S.R., Faroe Is., Iceland (Spencer, 1976: 462), Poland (Spencer, 1990) and Czech Republic (Martinez in Fauna Europaea).
