The Diana Fritillary is one of North America's most spectacular butterflies, with striking sexual dimorphism: males are tawny orange and black, while females mimic the Pipevine Swallowtail with iridescent blue-black hindwings. It is restricted to the Appalachian highlands and adjacent lowlands and is a species of conservation concern. Males emerge weeks before females each summer.
