I found this caterpillar eating elm leaves, on 6/7/09
This is the same caterpillar on 6/10/09
It pupated on 6/15/09
The adult emerged on 6/27/09
I found another chrysalis on 6-28-09. It was very light colored – almost white – so I thought it might be parasitized.
But it hatched into a butterfly on 7-4-09.Â It was much more cooperative, so I got pictures of both sides of its wings.
