Leaf-mine: Mine only in the leaf lamina (not the mid-rib). Mine not simultaneously blotch-like (on the upper side or under side) and with very fine frass grains. Mine not touching the midrib. Mine at least in places greenish in transmitted light when seen from either the dorsal side or ventral side. Frass plentiful, irregularly scattered throughout the mine. Pupation always external. The egg shell lies on the leaf surface at the beginning of the mine.

Larva: Details unknown.

Puparium: Details unknown.

Distribution in Great Britain and Ireland: Recorded in Britain by Ackland (1978) including Cambridgeshire, Glamorgan, North Somerset and West Gloucestershire (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 (Hering, 1957) including Germany (Griffiths, 1982), Austria, Czech Republic, Denmark, French mainland, Hungary, Italian mainland and Slovakia (Michelsen, in Fauna Europaea).

Also recorded in the East Palaearctic and Nearctic Regions (Michelsen, in Fauna Europaea).
