Any of several North American species of black-and-yellow swallowtail butterflies.
The eastern tiger swallowtail ( Papilio glaucus ) is a large, widely distributed species. The yellow male has black margins and black stripes on the wings. The female is similarly marked in the north, where the black and distasteful pipevine swallowtail ( Battus philenor ) does not occur; in the south, where the two coexist, the female tiger swallowtail is very often all or mostly black.
