Variegated Fritillary

Euptoieta claudia

Summary 5

The Variegated Fritillary (Euptoieta claudia) is a North and South American butterfly in the family Nymphalidae. Even though the Variegated Fritillary has some very different characteristics from the Speyeria Fritillaries, it is still closely related to them. Some of the differences are: Variegated Fritillaries have 2–3 broods per year vs. one per year in Speyeria; they are nomadic vs. sedentary; and they use a wide range of host plants vs. just violets. Variegated Fritillaries use passionflowers as a host plant, they also have taxonomic links to the heliconiines. Their flight is low and swift, but even when resting or nectaring, this species is extremely difficult to approach, and, because of this, its genus name was taken from the Greek word euptoietos meaning "easily scared".There are no Speyeria in Florida.
