A rather common species in Belgium, more frequently observed in the north of the country.
The larva lives at first in the opening buds of Prunus spinosa, but also of Crataegus, Malus or Sorbus aria, later on in a folded leaf-edge, and finally in spun leaves. Pupation in a flimsy cocoon in a folded leaf, or in debris on the ground. The adult hibernates. The moths are active at dusk and later occasionally come to light.
The adults have been observed from the end of July till May.
