Speyeria callippe meadii
Speyeria callippe meadii is a subspecies of the Callippe fritillary butterfly, a member of the brush-footed butterfly family Nymphalidae. It belongs to the greater fritillary genus Speyeria, which comprises large, orange-brown butterflies with distinctive silvery spots on the wing undersides. The subspecies was described by W.H. Edwards in 1872. Like other Speyeria fritillaries, it maintains an obligate relationship with violet plants (Viola spp.) as larval host plants.
Speyeria mormonia erinna
Mormon Fritillary
Speyeria mormonia erinna is a subspecies of the Mormon fritillary butterfly, a member of the brush-footed family Nymphalidae. Like other Speyeria species, it is closely associated with violet host plants for larval development. Research on congeneric species has demonstrated that this group relies primarily on visual cues for navigation to suitable habitat patches. The subspecies is distributed across prairie and montane regions of western Canada.
