one flight from (late) August to October. In captivity sometimes earlier. Eggs overwinter.
Not difficult. Take the eggs out of the fridge as soon as the hawthorn or willows are starting to regrow. Caterpillars prefer the very young and fresh leaves. Growth is fast (ready to pupate within 4 to 5 weeks). The cocoons oversummer and the moths appear as soon as the nights become cooler. Keep in well ventilated plastic containers at room temperature. The eggs overwinter.
