Parsley worm is what they called it when I researched what on earth this thing was when I found it a few years ago, my family raised parsley every year and I had never seen it before, and if my grandfather had found it eating his parsley, I would have heard about it in no uncertain terms, in two languages! I thought it was sweet that the woman who answered my question said she always plants additional parsley especially for them. And I saw pictures of the Black Swallowtail butterflies when I read that article, but never in a million years thought I would see any in person. But when I saw them the following year, I couldn't get over it. That was about three years ago now, never saw them again, caterpillar or butterfly. I think I'm going to learn a lot from you!
I didn't think about the birds, so I guess I should keep the parsley on the lower deck where I have some control, even though I really don't have any birds. I can't shake the feeling that I'm going to put a lot of time, money, work, research and hope into my new property, just to end up with some gladiatorial Darwinian bloodbath by the 4th of July!!!
