Quick facts for kidsVariegated Fritillary
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".
The upper side of the wings is orange and black. The fore wing and hind wing have a row of submarginal black spots and black median lines running across the wings. (Submarginal means just inward of the wing edge. Median means through the center of the wing.) 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. The wingspan is 1.75-2.25 inches.
There is a butterfly similar to the Variegated Fritillary. It is the Mexican Fritillary (Euptoieta hegesia). The Mexican Fritillary is brighter orange. The upper side of its hind wing has more orange. The underside of its wings is plainer, with no submarginal spots or median black lines.
