I felt kind of bad because the deer and rabbits ate all of the stuff I’d planted for Black Swallowtail butterflies, but I needn’t have because I have US Marine butterflies. No Golden Alexander, dill, parsley, fennel, or carrot? Fine…we’ll use rue. I’d planted the rue for Giant Swallowtail, which I’ve had only one year, but it’s a perennial, and it hasn’t died so far. I now have a pretty good idea of what kind of swallowtail chrysalis was on the west side of the house because it was only about 15′ from the bed where the rue lives.
