Leaf-mine: A long, whitish linear-blotch mine, frequently associated with the mid-rib (Spencer, 1976: 321 (fig. 583), 323).

Unusually long (up to 16 cm), upper-surface, whitish corridor. Often the corridor crosses itself so repeatedly that a secondary blotch develops. Sometimes a few small grains of frass in the initial part of the mine. Otherwise the mine is either completely free from frass, or a few big lumps are deposited at the very end of the corridor. Pupation outside the mine (Bladmineerders van Europa).

The mine is illustrated in the Encyclopedia of Life.

Larva: Posterior spiraclesd with c. 30 bulbs (Bladmineerders van Europa).

Puparium: Reddish; posterior spiracles on large conical projections, each with up to 24 irregular bulbs extending upwards (Spencer, 1976: 323). The puparium is illustrated in the Encyclopedia of Life.

Distribution in Great Britain and Ireland: Widespread in southern Britain including Surrey (Box Hill and Coulsdon), Gloucester. (Kilcot), Denbighshire (Cefn-y-bedd) (Spencer, 1972: 65); Warwickshire (Harbury) (Robbins, 1991: 108); North Somerset and South Wiltshire (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: 65).
