I have successfully raised many Monarchs years ago. For the past few years the property seems to burst with Black Swallowtail cats but that's it. I grow extra dill and parsley for them but they grow so far and disappear. They were food to something. So this year since I am too broke to buy trees for the different BF and because the BWT need me, I am raising any cats I find in a butterfly enclosure. That's fine but I would LOVE to raise Lunas. My big dream. I have looked everywhere for sweetgum trees around here. Nothing. I saw a few weeping willows at a neighbors maybe I could sponge off of. The only tree on the list on my property is a black walnut. Has anyone successfully raised Lunas on Black Walnut tree leaves?

Thanks so much for your help.
