Speyeria hydaspe, the Hydaspe fritillary, is a species of orange-brown butterfly found in the western portions of the United States and Canada. A small fritillary, it usually has cream-colored underwing spots, but the Vancouver Island subspecies has silver spots. It is similar to S. zerene and S. atlantis, but may be distinguished by the smooth and even appearance of its postmedian spotband. The caterpillars feed on violets including Viola glabella. A single brood flies from July through September and feeds on flower nectar. They may be found in moist forests, in clearings and subalpine meadows.

<i>Euptoieta claudia</i> Species of butterfly

Euptoieta claudia, the variegated fritillary, 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 two or three 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. And because of their use of passionflowers as a host plant, variegated fritillaries also have taxonomic links to the heliconians. 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".
