A not so common species throughout Belgium, more frequently observed in the northwestern and southern part of the country.
Hibernates as an egg, laid in small groups on twigs of the larval food plant. Pupates in a cocoon formed in soil or leaf litter. The adults come to light and sometimes also on sugar.
