Leaf-mine: Mine beginning on lower surface, the linear upper surface section eaten out somewhat irregularly at sides (Spencer, 1972: 80).

Corridor mine; the corridor begins with a lower-surface spiral or patch. The upper-surface corridor that follows has very irregular sides, and frass in long pearl chains. Pupation outside the mine (Bladmineerders van Europa).

A narrow gallery similar to P. vitalbae, but starting on the lower surface. The linear upper section eaten out irregularly at sides (British leafminers).

Larva: The larvae are described by de Meijere (1928, as auricomi) and the posterior spiracle is illustrated in Bladmineerders van Europa.

Puparium: Dark brown (Spencer, 1972: 80).
