Leaf-mine: Larva forming a narrow, unusually long, upper surface leaf-mine up to 12 cms, sometimes considerably widening at end; young leaves are frequently distorted (Spencer, 1976: 93, fig. 130).

An unusually long, upper-surface corridor that widens only little and winds freely through the leaf. Frass in two neat rows. Pupation outside the mine; exit slit (always?) in the lower epidermis (Bladmineerders van Europa).

A long, greenish, winding, upper surface gallery which sometimes broadens considerably at the end (British leafminers).

Larva: Yellow. Anterior spiracles each with 10 bulbs, posterior spiracles with 3 bulbs (Skuhravá and Roques, 2000). The larva is illustrated in Bladmineerders van Europa.

Puparium: Reddish brown; posterior spiracles each with 3 bulbs (Spencer, 1976: 93).
