Papilio polyxenes
Both male and female Eastern Black Swallowtails are bluish-black with yellow spots on the wings. They also have two orange eyespots with black dots in the middle. The male has a yellow band on the hindwings with a blue cloud under it. The female has a row of yellow dots above a blue band. It's easiest to remember that males have more yellow, and females have more blue.
