5/23/2010 – female came to lights
Another view that shows her size – one wing is almost as long as my finger.
I kept her in a cage overnight, and she laid about 12 eggs. They were green at first, and then they turned purple.
First instar caterpillars – 6/3/2010
6/30/2010 – eating an aspen leaf
They pupated shortly after this. This photo of the pupae was taken on 9/20/2010.
The pupae were kept in the refrigerator all winter, and then placed outside in late March. The first adults started hatching at the beginning of June 2011.
Reared female emerged 6/2/2011
I put released her onto a small tree outside our house. By the next day she had attracted a mate.
