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.
The Diana fritillary is a fritillary butterfly found in several wooded areas in southern and eastern North America. 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.
Myrtle's silverspot is a medium-sized butterfly in the brush foot family (Nymphalidae), an endangered subspecies of the zerene fritillary. It is endemic to California, where it is known from only about four locations just north of the San Francisco Bay Area, including two at Point Reyes National Seashore. Its wingspan is approximately 2.2 inches (56 mm). The upper surfaces of the wings are golden brown with numerous black spots and lines. The undersides are brown, orange and tan with black lines and silver and black spots. Larvae are dark colored with many sharp branching spines on their backs. Myrtle's silverspot is larger and paler than the closely related Behrens' silverspot, which is now limited to the vicinity of Point Arena in Mendocino County. Myrtle's silverspot is also closely related to the Oregon silverspot.
Speyeria, commonly known as greater fritillaries, is a genus of butterflies in the family Nymphalidae commonly found in North America, Europe, and Asia. Some authors used to consider this taxon a subgenus of Argynnis, but it has been reestablished as a separate genus in 2017.
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".
The Aphrodite fritillary is a fritillary butterfly, from North America.
Speyeria atlantis, the Atlantis fritillary, is a butterfly of the family Nymphalidae of North America. It is from the Avalon Peninsula of Newfoundland and Labrador to northern British Columbia, across the northern United States south as far as Colorado and West Virginia. It resides as far north as James Bay. The species is listed as endangered in Connecticut.
Speyeria edwardsii, the Edwards' fritillary, is a butterfly of the family Nymphalidae of North America. It is common from Alberta east to Manitoba and south as far as northern New Mexico.
Speyeria callippe, the callippe fritillary, is a North American species of butterflies in the brush-footed family Nymphalidae.
Speyeria coronis, the Coronis fritillary, is a butterfly of the family Nymphalidae of North America. It is common from Baja California to Washington and east to Colorado and western South Dakota and once reported in Alberta.
Speyeria mormonia, commonly known as the Mormon fritillary, is a North American butterfly belonging to the family Nymphalidae. It is highly diverse, having differentiated into several subspecies which occupy a wide geographic range. S. mormonia exhibits extreme protandry, which is the emergence of male adults before female adults. This has several consequences on male and female behavior. Habitat specificity is still being investigated, as there are few known environmental predictors, and S. mormonia appears to be associated with a wide range of habitats. This species is not under threat, and conservation efforts are generally not necessary.
Argynnis is a genus of butterflies in the family Nymphalidae, one of several groups known as "fritillaries".
Speyeria egleis, commonly known as the Great Basin fritillary or egleis fritillary, is a butterfly of the family Nymphalidae. It is found in North America, where it has been recorded from North Dakota southwest through Oregon to California and south to Colorado. The habitat consists of mountain meadows, forest openings and exposed rocky ridges.
Speyeria carolae, or Carole's fritillary, is a butterfly in the family Nymphalidae. It was described by Cyril Franklin dos Passos and Lionel Paul Grey in 1942 and is found in North America, where it has only been recorded from the Charleston Mountains of Clark County, Nevada. The habitat consists of mountain slopes, foothills and forest openings.
