A very rare species in Belgium.
It pupates on the underside of a leaf in a typical white silken cocoon with a large open mesh.
The moths come to light and can easily disturbed by day from the food plant.
The adults have been observed in Belgium from early May towards late Oktober in two generations a year.
The larvae feed on Brassicaceae, including Hesperis matronalis.
