Egg of a Cloudless Sulphur on Cassia tree in my backyard. October 3, 2008.

First instar larva in my garden. I don't think it lasted long thanks to the ants. September 27, 2008.

This one is farther along, though still pretty small. I kept a new plant in its pot and put that in a water basin "moat" to keep the ants out, and this one is doing well. November 26, 2008.

Now that this little tree is more mature, the Cloudless Sulphur caterpillars have had a better chance of outlasting the ants, as this one has. October 22, 2009.
