Oviposition is in the ground; larvae therefore have to search and mount a host plant. Large, glassy, irregular blotches without a recognisable preceding corridor. Frass in a black mass, mainly in the oldest part of the mine. The larvae move several times, and can also bore in the stem and underground parts.
Larvae in July – September (Bland ao, Britain, 2002a); several generations per year in warmer regions.
BE recorded (Phegea, 2009).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).
