Can you see it on the dill plant? We had two on our parsley and the boys and I were watching it grow everyday. Then one day they were gone. A few days later David told me about the caterpillar he found on my herbs and he tried to feed them to the chickens. After I told him about them being our science experiment, he said he didn't know they were our pets.
So the boys and I were a bit excited when he found more in the garden on the dill plant. We've been watching them get BIG. Then they disappeared and David had nothing to do with.
