Biology

Little is known about the biology of the species. Although the grapevine (Vitis vinifera ) is mentioned in the literature, so there is nothing to show that the caterpillars have been grown on this plant. Rather, it is assumed that the first description Diakonoff Herrich - Schaffer followed the mentioned 1854 "will take place on vines in July ". In various evidence of caterpillars on the buds of apple trees (Malus ) and young shoots of the interventions leagues hawthorn (Crataegus monogyna ) is apparently to avoid confusion with the melanistic form of Blastodacna atra. The moths fly from early June to early August.
