Leaf-mine: Blotch, near the leaf tip, containing one or two larvae; pupation outside the mine (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 Darvas, Skuhravá and Andersen (2000); mandible with 2 teeth; front spiraculum with 8, rear spiraculum with 3 bulbs. The bulbs of the rear spiraculum are elongated and S-shaped, like in cinerascens and intermittens (d'Aguilar, Chambon and Touber, 1976a) (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).

Reddish-brown, but the anterior segments are noticeably darkened, almost blackish; posterior spiracles each with 3 bulbs, the two processes separated by approximately their own diameter (Spencer, 1976: 121).

Hosts in Great Britain and Ireland: Currently unknown.

Time of year - larvae: Currently unknown. There is apparently only one generation per year (Spencer, 1976: 121).

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Added to British checklist by Cole in Chandler (1998: 136). Recorded from Cambridgeshire (NBN Atlas). Also recorded in the Republic of Ireland (Fauna Europaea).

Distribution elsewhere: Widespread in continental Europe. Described from northern Italy. Recorded in Denmark, Sweden, Finland (Spencer, 1976: 121), Germany (von Tschirnhaus, 1999), Austria, Czech Republic, Lithuania, Slovakia, Spanish mainland and The Netherlands (Fauna Europaea).
