A rare and local species throughout Belgium. Populations have declined because of the Dutch elm disease.
The larva feeds on the seeds, flowers and leaves. Later on, it accepts also various species of herbaceous plants. Hibernates as an egg on the twigs of the foodplant. The adults come to light and sugar.
The adults fly in one generation a year: from early September till late October.
