Black swallowtail butterfly caterpillar (I think)

Found two of these in my garden. I think they are black swallowtail butterfly caterpillars. The supposedly eat plants from the carrot family, though they are not in my carrot bed (yet?). Should i be worried about them?

Looks exactly like my place. They wiped out a few dill plants just like yours, not much else.

Yes, I believe that is a black swallowtail caterpillar. I love them, I plant extra dill and parsley hoping to attract them, and the only one I found was on a queen anne's lace this year. I keep looking! I do not consider them a pest, but a guest.

Excellent! Thank you for your reply.

I don't consider them a pest either, but as a chicken snack. Chickens really like the bubble gum flavor they give off.
