The adults fly in two generations a year; onwards from early May till June and in August. They are active in the evening.
The young larva mines the leaf of Leucanthemum vulgare in a long gallery, sometimes changing to another leaf. Later, it feeds externally on the underside of the leaf. Pupation in a white, ribbed cocoon on a leaf or the adjacent herbage.
