Speyeria atlantis (W.H. Edwards, 1862) | |
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. [1] [2] It resides as far north as James Bay. The species is listed as endangered in Connecticut. [3]
Its upperside is dark orange with many rows of black markings and black wing margins. Its underside is a light brown with many silvery-white spots. Wingspan ranges from 50–64 millimetres (2.0–2.5 in). [1] [4]
The larvae are hosted by violets. Adult foods include common milkweed, mint, mountain laurel, crown vetch, burdock, boneset, ox-eye daisy, spiraea, and virgin's bower. [5]
Atlantis fritillaries are sensitive to temperature [6] [7] with population trajectories showing declines in response to climate warming trends. [7]

Speyeria zerene, the zerene fritillary, is a butterfly found in the western portions of the United States and Canada. The species was first described by William John Swainson in 1827.
The great spangled fritillary is a North American butterfly of the family Nymphalidae.
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.
The regal fritillary is a striking nymphalid butterfly found among some of the remaining tallgrass and mixed-grass prairies in the east-central United States. This prairie-specialist butterfly has a characteristic deep orange color and unmistakable dark hindwings with two bands of spots. On the female, both bands of spots are white. However, on the male, the outer band of spots is orange in color. Females also tend to be slightly larger than males. The ventral surface of the hindwings is olive brown to black in color with bold silvery white spots. The wingspan of S. idalia usually measures 68–105 millimetres (2.7–4.1 in). Flight is in the summertime from approximately June to September and adults tend to be swift in flight, coasting close to the ground. It is listed as a species of special concern and believed extirpated in the US state of Connecticut.
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.
The Aphrodite fritillary is a fritillary butterfly, from North America.
Speyeria hesperis, the northwestern fritillary, is a butterfly of the family Nymphalidae. It is found in the northwestern United States and western Canada, as far east as Manitoba and the Dakotas.
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 adiaste, the unsilvered fritillary or adiaste fritillary, is a species of butterfly of the family Nymphalidae. It is found in California north to San Mateo County and east to north Los Angeles County and Kern County.
Speyeria egleis, commonly known as the Great Basin fritillary or egleis fritillary, is a butterfly of the family Nymphalidae. It is found in the United States, 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.
Speyeria nokomis, the nokomis fritillary, is a species of fritillary in the family of butterflies known as Nymphalidae. It is found in North America.
