Spilosoma virginica – Virginian Tiger Moth

7/28/2012  I found some unknown eggs on Lamb's Quarters (Chemopodium)

 

7/31/2012  The eggs hatched.

 

8/9/2012  2nd or 3rd instar

 

8/14/2012  late instar

 

8/17/2012  I gave the caterpillars the host plant, dry leaves, and soil for choices since I didn't know what they needed for pupating.

 

8/21/2012  Here's the cocoon in the plastic container.  Actually it is two cocoons, because the second caterpillar made its cocoon right on top of the first cocoon.  I was afraid to take the lid off the container for fear of damaging the pupae.

 

8/29/2012  After a few days, when both cats had cocooned, and I was sure that they had made pupas, I took the lid off.  I was getting worried that it was going to get moldy in the container.......this is the cocoon from the top.
