Leaf-mine: Full depth mine; in parts of the mine the parenchyma remain untouched. The larva enters and exits the leaf by means of an oval opening of 3-5 mm at the base, near the leaf edge. Pupation external (Bladmineerders van Europa).

Forms a deep mine with plentiful frass. The larva changes leaves entering and leaving near the leaf edge (British leafminers).

Larva: The larva is described Rotheray (1988) and Stuke (2000). Posterior spiracles on a large common black spot; mandible with one tooth (Bladmineerders van Europa).

Puparium: Details unknown.

Comments: Chandler (1978) did not indicate whether his host records were British or Foreign and are therefore tentatively included under 'Hosts in Britain' and 'Hosts elsewhere'.

Time of year - mines: May - June (British leafminers).

Distribution in Great Britain and Ireland: Widespread in southern England including Anglesey, Berkshire, Caernarvonshire, Cambridgeshire, Cardiganshire, Dorset, East Cornwall, Merionethshire, Montgomeryshire, North Hampshire, Oxfordshire, Shropshire, Surrey and West Kent (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 (Speight, 2004 in Fauna Europaea). Also Beltany approach path, Raphoe, Co. Donegal (British leafminers).
