I did not know that - will do that if I ever get hornworms again. got a bunch of devils claw in the pasture that showed up a few years ago - pretty flower and trippy seed pods - although I have to pull a lot of them up they are good at taking over a pasture and my goats only eat it once I pull it up then it's just a nibble. but a few I leave because they are just interesting plants.
I actually love tomato hornworms, they are so beautiful and the moths are spectacular! I try to move the tomato worms to our native Devil's Claw plants, the only non-nightshade plant these guys eat.
