|A beautiful "worm"|
No—your first thought of killing them doesn’t get thumbs-up here because the “worms” are more good than bad. They are bad in the sense they’ll eat some of your dill and parsley—and maybe some of the foliage of your carrots and celery too—but they are good because they are caterpillars or larvae of the black swallowtail butterfly (Papilio polyxenes). Parsley gives both the caterpillar and the adult their nicknames, “parsley worm” and “parsley swallowtail.”

And as the summer wears on, let some of your dill go to seed, so you’ll have volunteer plants next year to add both herbal essence and food for the black swallowtail caterpillars to your 2012 garden.
Take a second look at the “worm.”
Beautiful, isn’t it?
