Leaf-mine: The mine is underside, occupying the whole leaflet, which turns down at edges (British leafminers).

Lower surface tentiform mine that occupies an entire leaflet; lower epidermis strongly folded. Fully developed mines are strongly inflated and the leaflet is so completely folded over the mine that the latter becomes practically invisible. In this stage the larva has consumed also all tissue in the roof of the mine, making the mine very conspicuous (Bladmineerders van Europa).

Larva: Details unknown.

Pupa: Cremaster with two pairs of spines. The inner pair has shifted so far sidewards that the inner and outer pairs seem to form one whole. The inner spines are fairly slender, the outer ones are stout, and the two combined look like one long spine with a broad base (Gregor and Patocka, 2001a; Patocka and Turcani, 2005a) (Bladmineerders van Europa).

Adult: Not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidopetra Dissection Group (check for update).

Distribution in Great Britain and Ireland: Britain including East Sussex, 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) and Northern Ireland (Karsholt and van Nieukerken in Fauna Europaea). It occurs on woodland rides and the bottom of hedges (British leafminers). See also British leafminers distribution map.

Also recorded in the Republic of Ireland (Karsholt and van Nieukerken in Fauna Europaea).
