Leaf-miner: Brownish lower surface blotch. The leaves finally are completely eaten out and turn whitish. Pupation within the mine; the pupariumprium mostly is located in the leaf tip (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.

The larva is described by Griffiths (1976a), who points out that the earlier description by Hering (1954a) is erroneous (Bladmineerders van Europa).

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:

Sedum album White Stonecrop British Wild Flowers by John Somerville et al. Bladmineerders van Europa
Sedum rupestre Reflexed Stonecrop British Wild Flowers by John Somerville et al. Bladmineerders van Europa

Time of year - mines: June and August (Bladmineerders van Europa).

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: First recorded as new to Britain by Gibbs (2008).

Distribution elsewhere: French mainland, Germany, Spanish mainland, Yugoslavia (Fauna Europaea).

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