Leaf-mine: Linear mine, although the maze of galleries formed sometimes appears to form a false blotch. Pupation internal, at the end of the mine or external.

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:

Crassulaceae        
Sedum rosea Roseroot British Wild Flowers by John Somerville et al. Bland, 1995: 267-269

Hosts elsewhere:

Crassulaceae        
Rhodiola       Spencer, 1990: 101
Sedum       Spencer, 1990: 101

Time of year - mine: June-August.

Time of year - adults: May the following year.

Distribution in Great Britain & Ireland: Restricted to montane habitats - Angus (Glen Doll and area) and Perth (Meall nan Tarmachan) (Bland, 1995).

Distribution elsewhere: Holaractic. Europe (Spencer, 1990: 99). No country names given in Spencer, 1990 or Martinez (2004 in Fauna Europaea). Norway (Bland, 1995).

Also recorded in Canada (Yukon Territory) (Spencer, 1990: 99).
