I was thrilled to find 4 small Monarch caterpillars on my butterflyweed, Asclepias tuberosa, yesterday afternoon. I just hope they don't eat the flower buds! No caterpillars on the parsley, dill, spicebush, pipevine, lambs quarters or American senna.....YET. (It's only a matter of time.) Bill Haley Chattanooga, TN
