Two butterflies

Two butterflies on the butterfly bushes.

A female Eastern Tiger Swallowtail

A Great Spangled Fritillary. In the west, males and females are quite different, and neither look quite like this, but in the East you can't tell them apart by looking (unless, I suppose, you are also a Great Spangled Fritillary). Note how different the inner- and outer-wing patterns are; note, too, the tiny forelegs making the butterfly look four-legged. Both of those are characteristic of Brush-footed butterflies, which fritilaries are among.
