I found this caterpillar eating oak leaves on July 8, 2009.
July 28, 2009 – attaching to a leaf with silk
August 3, 2009 – eating.
It pupated against the glass bottom of the container, surrounded by a net of silk.Â August 11, 2009
I kept the pupa in a plastic container in the refrigerator all winter.Â I took it out in March, and this adult hatched on June 19, 2010.
