Antheraea polyphemus




throughout most of Canada and the USA


In between 12 and 14 cm


multiple flights. Pupae overwinter.

Food plants:

Quercus, Betula, Alnus, Corylus, Fagus, Castanea, Carpinus, Juglans, Ulmus, Acer, Rosa, Prunus, Malus, Pyrus,  and many more


One of the easiest Silkmoths to rear, very suitable for newcomers and even children. Keep at room temperature in spacious, well ventilated plastic containers. Try not to overcrowd (difficult when you know how easily this species pairs and how many eggs 1 female deposits). Caterpillars are ready to pupate within 4 to 5 weeks. The pupal stage in summer is short (approximately 3 weeks or less). The cocoons from the last flight in autumn can be stored in the fridge until spring.
