Mystery Solved

My beautiful spiky caterpillar is an American Lady. It is a true Bush-footed Butterfly. The American Lady is not in any danger at this time. Probably because the caterpillars eat a species of plants that are readily available. The caterpillars eat plants in the sunflower family and burdock is one of those plants. I think my little one started off on my Black-eyed Susan flowers as they are right beside the Pussy-toes. Both of those plants are in the family of plants that they use for food. However now that it has been eating a steady diet of Pussy-toes it doesn't want anything else so I had to put some more pussy-toes into a pot for him as most of the ones in the first pot are all eaten. I hope it becomes a chrysalis soon as I don't think I can keep potting up my pussy-toes. A great website for butterfly information is http://www.butterfliesandmoths.org
