Black Swallowtail Caterpillar photographs

These are some photographs of Black Swallowtail Caterpillars(Papilio polyxenes).  I planted some Parsley plants in my garden.  These caterpillars showed up and ate all of the Parsley.

Black Swallowtail Caterpillars are orange, white and black.  The pattern can vary quite a bit so its not easy to describe them.  They are usually mostly white with orange spots or stripes and black stripes.  Black Swallowtail Caterpillars like to eat Parsley and related plants.
