Leaf-mine: A mine between veins from midrib to leaf-edge, narrow, tubular, with one crease in lower epidermis (British leafminers).

Narrow, finally tubular lower-surface mine between two side veins. The lower epidermis with one strong fold. Pupa in a flimsy cocoon in a corner of the mine, usually in the axil of midrib and side vein. Frass loosely heaped in the opposite corner (Bladmineerders van Europa).

Larva: Details unknown.

Pupa: The pupa and cremaster are illustrated in British leafminers and Bladmineerders van Europa.

Adult: The adult is illustrated in UKMoths by Rob Edmunds. The genitalia are not illustrated by the Lepidoptera Dissection Group (check of update).

Hosts in Britain:

Hosts elsewhere:

Time of year - larvae: June - July, September - October (British leafminers).

Time of year - adults: Two generations, flying in May then again during July and August (UKMoths).

Distribution in Great Britain and Ireland: Mainly in the south-east of England (UKMoths) including Bedfordshire, Cambridgeshire, Denbighshire, East Kent, East Norfolk, East Suffolk, Glamorgan, Middlesex, North Essex, Surrey, West Kent, West Norfolk and West Suffolk (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). See also British leafminers distribution map. Occasionally found elsewhere, probably as an introduction with the foodplant (UKMoths).
