Leaf-mine: An irregular linear mine, which in small leaves can form a secondary blotch.

Long, upper-surface corridor, winding through the leaf and frequently crossing itself; in small leaves often a secondary blotch in the end. Frass in short strings and pearl chains. Pupation outside the mine (Bladmineerders van Europa).

An irregular gallery, sometimes crossing over, with black frass arranged as elongate very narrow streaks at the sides of the mine (British leafminers).

Larva: The larva is described by Dempewolf (2001: 150) and illustrated in Bladmineerders van Europa.

Puparium: Orange; posterior spiracles each with 3 bulbs.

Distribution in Great Britain and Ireland: Widespread in Britain including Hertfordshire (Barnet), Devon (Slapton), Glamorgan (Cardiff), Sutherland (Loch Assynt) (Spencer, 1972: 54); Warwickshire (Alleslley, Hartshill, Coventry and Wilncote) (Robbins, 1991: 113); Cambridgeshire and East Sussex (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).

Also recorded in the Republic of Ireland: Co. Clare (Spencer, 1972: 54).
