Black Swallowtails are attracted to parsley and carrot plants, and take nectar at various flowers including phlox and milkweeds. Their flight is much less frenzied than the pipevine swallowtail, which it resembles. Black Swallowtails' flight is swooping and dipping. They are not easily disturbed, but when they are, they take off like the proverbial bat out of you-know-where.
