between six and a half and seven and a half centimeter
one flight annually (from May to mid July), cocoons overwinter
Robinia and other woody Fabaceae preferred. Less easy on Quercus.
Not difficult but some experience is required. Keep in well ventilated plastic containers also when older. This helps to keep the food plants fresh enough (cut Fabaceae don't last very long)-. Watch out for condensation and do not give wet leaves. Fast growing and ready to pupate in approximately six to seven weeks . A living room temperature is enough. The cocoons overwinter in a cool, unheated, frostfree room (not in the fridge). Moths emerge only after a longer period of warmer weather.
