The Black Swallowtail (Papilio polyxenes) also called the American Swallowtail or Parsnip Swallowtail is a butterfly found throughout much of North America. It is the state butterfly of Oklahoma. After mating, small, yellow eggs are laid, typically on plants from the carrot family, Apiaceae, including dill, fennel, Queen Anne's lace, parsley, and golden alexanders. They are also found eating rue and bishop's weed. First instar larvae grow to about 1.5 cm (0.59 in) long and resemble bird droppings.
