The (Eastern) Black Swallowtail is a butterfly found throughout much of North America. It has a wingspan of 3.1 to 4.3 iches. The upper surface of the wings is mostly black. On the inner edge of the hindwing is a black spot centered in larger orange spot. A male of this species has a yellow band near edge of wings; a female has row of yellow spots.

Here's a whimsical interpretation of the Black Swallowtail Caterpillar. I took this photo at the South Carolina Botanical Garden earlier this year.
