Leaf-mine: A narrow linear mine which can develop into a secondary blotch (Spencer, 1976: 517).

Upper-surface mine in the tip of a leaf segment in primary corridor, but quickly turning into secondary blotch within the limited space of the leaf segment. The mine begins in the very tip of the segment, this initial section later becomes unrecognisable. Frass in fine granules. Pupation outside the mine (Bladmineerders van Europa).

Larva: The larva is described by de Meijere (1926). Posterior spiracles each with approx. 22 bulbs.

Puparium: Black; posterior spiracles each with some 22 bulbs (Spencer, 1976: 517).

Distribution in Great Britain and Ireland: Recorded as new to Britain by Irwin (1985: 103). Known from Cambridgeshire and East 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, Norway, Poland, Sweden (Spencer, 1976: 517), The Netherlands (Bladmineerders van Europa), Hungary and Lithuania (Martinez in Fauna Europaea).
