I don't know what it was using at the ranch. There is no penta out there. Will have to research what natives it might use. I don't recognize any of the larval hosts listed under BAMONA for it as growing at the ranch.
mamajack - I have the regular ruta graveolens. At least that's what it looks like. The Black Swallowtails out here prefer it over dill, fennel and parsley and every now and then I'll find Giant Swallowtail caterpillars on it.
