Leaf-miner: A long irregular mine in late summer and autumn, overwintering low in the stem, burrowing into a young leaf and continuing feeding the following spring (Spencer, 1976: 177).

At least part of the mine consists of a very long, narrow, full depth corridor that is almost free of frass. The larva moves from one leaf to the other by way of the leaf sheath; most frass to be found in the leaf sheaths (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 Nowakowski (1973) and Dempewolf (2001: 122).

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).

The puparium is unusually slender. Posterior spiracles club-shaped, with about 18 bulbs (Bladmineerders van Europa).

Time of year - mines: Probably from late autumn to May; hibernation in a leaf sheath (Bladmineerders van Europa).

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Widespread in England. Huntingdonshire (Woodwalton Fen), Suffolk (Barton Mills), Oxfordshire (Hall Copse) and Cambridgeshire (Chippenham Fen) (Spencer, 1972b: 107); Cambridgeshire, Dorset, Huntingdonshire, Northamptonshire, Oxfordshire and South Hampshire (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe, including Austria, [former] Czechoslovakia, Germany, Hungary, Denmark, Finland, Sweden (Spencer, 1976: 177) and France (Bladmineerders van Europa), Czech Republic, Estonia, Italian mainland, Lituania, Poland, Slovakia and Spanish mainland (Fauna Europaea).
