Leaf-mine: A funnel-shaped blotch mine at margin of leaf (Spencer, 1972: 36 (fig. 100), 38).

Blotch, invariably beginning at the leaf margin, widening fast and strongly, giving the mine a funnel-like shape. Primary and secondary feeding lines very conspicuous. Frass in large grains. The larvae leaves the mine before pupation; according to Spencer (1954) the exit slit is in the lower epidermis (Bladmineerders van Europa).

Larva: Posterior spiracles witth about 40 bulbs (Groschke, 1957a; Hering, 1957a) (Bladmineerders van Europa).

Puparium: Details unknown.

Hosts elsewhere:

Time of year - mines: June-July.

Time of year - adults: June. Only a single generation in summer.

Distribution in Great Britain and Ireland: Uncommon in England including Middlesex (Scratch Wood), Surrey (Chelsham) and Huntingdonshire (Monk's Wood) (Spencer, 1972: 38), Surrey (Godstone) (pers. observation) 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).
