Hooklike, upper-surface corridor. The corridor begins near the base of a leaflet, runs along the margin to the tip, then, quickly widening, redescends over the midrib towards the base of the leaflet. Frass in the corridor part in fine grains, further up in smal clumps. Pupation outside the mine. Older mines turn black, and then are somewhat easier to find.
Occasionally on Lupinus.
Larvae between April and September (Hering, 1957a).
BE recorded (Ellis: La Calamine).
NE recorded (de Meijere, 1924a).
LUX recorded (Ellis: Kautenbach).
