A very common species throughout Belgium, known from all provinces in every period.
The caterpillar at first feeds on the young leaves and later on the flower-buds and flowers of the food plant. It hibernates when small and resumes feeding in springtime. It rests on the underside of a leaf or along the stem. Its presence is revealed by brown spots on the leaf caused by feeding on the underside. Pupation at the underside of a leaf.
The adults are active at dusk and come to light.
One generation a year: from the end of May till September.
Ruderal places, wasteland, abandoned gardens.
