Leaf- and stem-miner: Mine predominantly in the leaves. The beginning of the mine is a full depth corridor lying on the leaf margin, with or without large, black frass grains. The larva goes through the stem, mines leaf after leaf, hollowing these out (Hering, 1957).

The larva mines a number of leaves, and bores in the stem segments inbetween. Frass, as far as visible, in large black lumps. Pupation outside the mine (Bladmineerders van Europa).

Larva: Details unknown.

Puparium: Details unknown.

Comments: Ackland in Chandler (1978) did not indicate whether his host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere'.

Hosts in Britain:

Hosts elsewhere:

Time of year - mines: July (Hering, 1957).

Time of year - adults: Unknown.

Distribution in Great Britain and Ireland: Recorded in Britain by Ackland (1978) including Anglesey, East Ross, East Suffolk, East Sutherland, Easterness, Glamorgan and West Norfolk (NBN Gateway - N.B. includes Watsonian Vice Counties having publicly available records that fall within or overlap the vice county border at 10km resolution or better i.e. a record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below).

Distribution elsewhere: Widespread in continental Europe including Germany (Teschner, 1999), Denmark, Norwegian mainland, Poland and Russia - North (Michelsen, in Fauna Europaea).
