The Diana fritillary (Speyeria diana) is a fritillary butterfly found in several wooded areas in southern and eastern North America (primarily in the Arkansas River valley, several counties in South Carolina, spots along the Appalachian mountain range, and a few places on the southern Cumberland Plateau).

[3] On February 28, 2007, Act 156 of the Arkansas General Assembly designated the Diana fritillary as the official state butterfly.

Introduced by Representative John Paul Wells of Logan County, the legislation for making the butterfly a state symbol took note of the butterfly's beauty, educational importance, and impact on tourism.

[4] The opposed threat to these magnificent species is climate change since it has altered and affected the Diana fritillary butterfly's natural habitat.

Other threats to the Diana fritillary butterflies include loss of habitat and agricultural development.
