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). The species exhibits marked sexual dimorphism, with males of the species exhibiting an orange color on the edges of their wings, with a burnt orange underwing. Females are dark blue, with dark, almost dusty underwings, and are also larger than males.[3]
The larvae feed on violet leaves. Dianas are unusual in that they do not lay their eggs directly on the host plant, instead scattering the eggs around the base of the plant. Upon hatching, larvae burrow into the ground over winter to emerge in spring. Adults feed on flower nectar and dung.[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. Arkansas is the only state to designate the Diana fritillary as its state butterfly; pairing it with its state insect, the honeybee. Arkansas is the twenty-sixth state to designate a butterfly as a state symbol.[4]
The opposed threat to these magnificent species is climate change since it has altered and affected the Diana fritillary butterfly's natural habitat. The Diana fritillary population in the Appalachian Mountains and populations living out west will have a decrease of their kind. Other threats to the Diana fritillary butterflies include loss of habitat and agricultural development. Overall, the Diana fritillary species is expected to have a population decrease by the year 2050. [5] [6]

Speyeria diana est une espèce nord-américaine de lépidoptères de la famille des Nymphalidae et de la sous-famille des Heliconiinae.
Speyeria diana a été nommé par Cramer en 1777.
Synonymes : Papilio diana Drury, [1777][1].
Speyeria diana se nomme Diana en anglais.
C'est un grand papillon d'une envergure de 87 à 113 mm, et présente un dimorphisme sexuel : le mâle est de couleur marron à large bordure orange alors que la femelle est noire avec les postérieures marquées de bleu.
Le revers des antérieures chez le mâle est marron à large bordure orange alors que les postérieures sont orange ornées de d'une ligne submarginale de chevrons blancs, chez la femelle le revers est brun marqué de bleu.
Il vole en une génération à partir de juin.
Ce sont les jeunes chenilles qui hivernent[2].
Les plantes hôtes de ses chenilles sont des Viola[1].
Il est présent en Amérique du Nord, dans le sud-est des États-Unis, principalement dans les Appalaches en Caroline du Nord, Alabama et Arkansas[1],[3].
Il réside dans les champs, les prairies, les vallées et les zones de pâturage[3].
Ce papillon est rare et ses populations doivent être protégées par protection de leur habitat[3].

Speyeria diana (Anglice Diana fritillary) est dimorphicus familiae Nymphalidarum papilio, in nonnullis Americae Septentrionalis meridianae orientalisque regionibus silvaticis endemicus, et praecipue in valle Fluminis Arcansiae, in aliquibus Carolinae Meridianae comitatibus, et in locis secundum Montes Appalachianos observatus. Is est publicum Arcansiae insectum.
Mari est color aurantius in marginibus alarum nigrarum. Femina autem est caerulea obscura,[2] et ea mare est multo maior.
Adulti ova recte in planta non pariunt, sed ea potius super solum circa plantam spargunt. Larvae, simul atque ex ovis excluduntur, se in solum infodiunt ut hiement; vere emergunt et foliis Violae vescuntur. Adulti nectar ex variis floribus sorbillant.[2]
