Today i was looking at my fennel in the whiskey barrel with some larkspur. Hey what is this? I have 2 large caterpillars munching away. I read the adults munch on fennel and the caterpillars munch on the milkweed. I have seen nothing on the milkweed but here are these 2 big boys, looking they are ready to cocoon soon. Maybe I will have some butterflies afterall. On the bottom picture you need to look below the stalk that is pretty bare and there he is. On the top picture look under the top spead of seeds.
