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.[2] 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.[2] 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.[3] References{{Commons category|Speyeria diana}}1. ^{{cite web|title=Speyeria diana Cramer 1779|url=http://www.eol.org/pages/162627|accessdate=2009-11-17}} {{Taxonbar|from=Q3062216}}{{Heliconiinae-stub}}2. ^1 {{cite web | title = Diana, Butterflies and Moths of North America | url = http://www.butterfliesandmoths.org/species?l=1674 | accessdate = 2008-09-15}} 3. ^{{cite web|last=Spencer|first=Lori|title=Mount Magazine State Park|url=http://www.encyclopediaofarkansas.net/encyclopedia/entry-detail.aspx?entryID=5236|work=Encyclopedia of Arkansas|publisher=Central Arkansas Library System|accessdate=31 May 2012}} 7 : Speyeria|Butterflies of North America|Butterflies of the United States|Natural history of Arkansas|Symbols of Arkansas|Butterflies described in 1779|Taxa named by Pieter Cramer |
