Euptoieta claudia
The Variegated Fritillary (Euptoieta claudia) is a butterfly in the family Nymphalidae. It is native to North America and South America. The Variegated Fritillary is closely related to butterflies in the genus Speyeria. It has some differences from Speyeria butterflies. Some of the differences are: Variegated Fritillaries have 2-3 broods per year vs. one per year in Speyeria. They travel more vs. staying in the same place. And they use a wide range of host plants vs. just violets. Variegated Fritillaries use passionflowers as a host plant. Because of this, Variegated Fritillaries have taxonomic links to the heliconians. Their flight is low and fast, and they are hard to approach. Its genus name was taken from the Greek word euptoietos meaning "easily scared".[1]

(Submarginal means just inward of the wing edge. Median means through the center of the wing.)[2][3] The underside of the fore wing is orange. The hind wing is mottled with browns and grays. There is a pale postmedian band (postmedian means just outward of the median). There is no silvering.[3] The wingspan is 1.75-2.25 inches.[4]

Life cycle
Females lay their eggs singly on the host plant's leaves and stems. The eggs are pale green or cream colored. The caterpillar eats the leaves, flowers, and stems of the food plant.[1][8] The caterpillar is red with black stripes. There are white spots in the black stripes. In many individuals, the white is more noticeable than the black.[9] It has six rows of black spines. It has a pair of long, clubbed spines on the head.[5][8] The chrysalis is shiny white with small black spots. It has a variable amount of brown markings and has orange and gold projections. Adults overwinter in the south and fly north each spring and summer.[8] It has 2-3 broods per year.[3]
