A rare and local species in Belgium, more observed in the northern part. Occasionally it can become a pest.
The larva feeds on the parenchyma on the upper surface of the leaf leaving the veins intact and thus creating a skeleton leaf appearance.
The adults are active during the day. The moths of the second generation overwinter and reappear in spring.
The adults fly in two generations per year: in July and during September.
Old gardens, orchards, forest edges.
