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.

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.
