This is a beautiful and fun species to rear, as the larvae get quite large, and they go from egg to cocoon in about 8 weeks, overwinter as cocoons, and hatch in May/June of the following year. These are great for beginners in this fascinating and rewarding hobby!

I created the following Website for those who are curious about raising these, and other large moth species.

Also called by the name Cecropia moth I got a larvae of it at the Minnesota State fair this year (2008) - they only have a very brief description about it - food - elm. Luckly I found out that it also eats birch and gave it some - it are hungry, and I had to clean out the sticks and dropping it left behind. Then it weaves a cocoon and then so far nothing else had happened.
