from Canada into Mexico
in between 10 and 12 cm
one to multiple flights (when kept warm). Pupae overwinter.
Juglans, Carya and Liquidambar preferred. Depending on origin of the stock sometimes (but most certainly not always) also Betula, Salix or Rhus
A very easy species, suitable for newcomers and children. Keep above 18°C and clean, in well ventilated plastic containers (just watch out for condensation). Fast growing and ready to pupate within 4 weeks. The pupal stage in between flights is short (approximately 2 to 3 weeks). The warmer the faster they develop. Cocoons after the last flight in autumn can overwinter in the fridge.
