White Admiral

Limenitis arthemis is a polytypic species of North American brush-footed butterfly, common throughout much of the eastern United States. L. a. arthemis has a large white band traversing both the forewings and hindwings.
Both sexes of this species are identical except that the females are slightly larger than the males.[1] The upper side of L. a. arthemis is mostly blackish-blue with white postmedian bands across both wings. Some individuals have a row of red submarginal spots, while others have this area being blue. The underside of the wings is a blackish color with a broad white postmedian band. The basal area of both wings contains many red spots. The submarginal area may contain a row of red spots and the marginal area having bluish spots. However, sometimes the submarginal and marginal areas are just a reddish-brown color
