Only caterpillars actually eat the leaves of the various plants; adult butterflies feed on nectar from various plant types. Caterpillars feed on varying members of the carrot family including parsnip (this butterfly is also sometimes called the parsnip swallowtail), Queen Anne's Lace, dill, parsley and others.
Like other butterflies, black swallowtails feed on flowering plants. The types of plants they feed from depends on their location and the availability of certain plant species.
The larval stage of Eastern Black Swallowtail (Papilio polyxenes) does have parsley as one of its host plants, meaning: the caterpillars eat parsley (as well as dill and carrot tops.) If you see them in your garden-- don't kill them! Plant more parsley and enjoy the beautiful adult stage.

Adult butterflies do not eat flowers; they eat the nectar produced by the flowers. Only the caterpillars eat the leaves and stems of certain plants. In the case of the Black Swallowtail butterfly, the adults will feed on nectar from most any flower that produces nectar including milkweed, red clover and thistles. The caterpillars feed on the leaves and stems of many plants in the carrot family such as dill, parsley, Queen Anne's Lace and others.
