The mine begins as a narrow corridor along the leaf margin, usually running around a leaf segment. Then follows a deep, therefore quite transparant, upper-surface corridor. Frass at first in two rows of grains, further on in more irregular, coarser grains. Pupation outside the mine; exit slit in upper epidermis.
Larvae in June (Hering, 1957a), own observations also in September.
