This species is easy to rear. They emerge days over, and pairing takes  
place after 22:00 and is short. Pairing is easy in a small cage. Fertile  
eggs show a black dot (like most automeris species do) after 2-3  
days. Larva first start to feed in groups, and in the later instar  
solitaire. When fully grown, they can reach 7 cm in length. They spin  
a paper thin cocoon. The more South you come, there are several  
generations. Species from Canada and northern USA have only 1  
generation. They can be kept cold for overwintering.
