A fairly common species in Belgium.
A white cocoon inside the mine.
The eggs are mainly deposited singly. The full-grown larva constructs a white silken cocoon in which it hibernates. Pupation in spring time. The adults are mainly active at dusk and come to light.
The adults fly in two, perhaps three, generations a year: from late April till June and again in August.
The larva lives on a variety of cultivated and wild Prunus species, in Belgium most recorded on Prunus avium and Prunus cerasus. It has also rarely been recorded on Malus.
