Leaf-miner: Upper-surface corridor, generally in the upper half of the blade, running up to the leaf tip, usually occupying more then half the width of the leaf. Frass in green stripes at either side of the corridor. Never more than one larva in a mine. Puparium within the mine, metallic black, not anchered with a string of silk (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 larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue. Posterior spiracles laterally with a large, finely spinulose wart that almost hides the trachea behind it. The two rear arms of the cephalic skeleton dark for most of their length (Nowakowski, 1973a). 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). Metallic black, deeply segmented; posterior spiracular processes generally as in Cerodontha incisa, but with the 3 bulbs more elongate, the lower two curving around the base of the hook-like upper one (Spencer, 1976: 195). Hosts in Great Britain and Ireland:
Hosts elsewhere: Time of year - mines: June-August (Bladmineerders van Europa). Time of year - adults: July-August. Distribution in Great Britain and Ireland: Widespread in Britain - Norfolk (Blakeney and Winterton) and Elgin (Culbin Sands) (Spencer, 1972b: 104); Glamorgan (NBN Atlas). Distribution elsewhere: Widespread in continental Europe including Denmark, Sweden, Germany, Poland and Russia (Spencer, 1976: 185), Czech Republic, French mainland, Hungary, Lithuania, Slovakia, Spanish mainland and Ukraine (Fauna Europaea). Also recorded in Canada and the U.S.A. (Spencer, 1976: 185). NBN Atlas links to known host species: British and Irish Parasitoids in Britain and elsewhere:
