Speyeria callippe macaria
Speyeria callippe macaria is a subspecies of the callippe fritillary butterfly, a member of the Nymphalidae family. This subspecies was named in honor of California lepidopterist Charles "Chuck" Hageman, who conducted extensive field research on California butterflies. The species is part of the Speyeria genus, commonly known as greater fritillaries, which are characterized by their close ecological relationship with violet host plants.
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 hesperis dennisi
Dennis' Fritillary
Speyeria hesperis dennisi is a subspecies of fritillary butterfly in the family Nymphalidae. As a member of the genus Speyeria, it belongs to a group of large, orange and black butterflies commonly known as greater fritillaries. The subspecies epithet "dennisi" honors an individual associated with its discovery or study. Like other Speyeria species, it is likely associated with violet family plants (Violaceae) for larval development, though specific ecological details for this subspecies are not well documented in the provided sources.
Speyeria hesperis irene
Speyeria hesperis irene is a subspecies of the Hesperis fritillary, a North American butterfly in the family Nymphalidae. It belongs to the greater fritillary group within the genus Speyeria, which are medium to large butterflies with characteristic silver spots on the undersides of their wings. The subspecies designation indicates geographic variation within the broader species S. hesperis. Like other Speyeria species, it is associated with violets (Viola spp.) as larval host plants. GBIF currently lists this taxon as a synonym of Speyeria atlantis, reflecting ongoing taxonomic revision in this complex group.
Speyeria hesperis ratonensis
Speyeria hesperis ratonensis is a subspecies of fritillary butterfly described by Scott in 1981. It belongs to the genus Speyeria, commonly known as greater fritillaries, which are characterized by their orange and black wing patterns and violet-feeding larvae. The subspecies epithet "ratonensis" suggests an association with Raton, New Mexico or the Raton Mesa region. Like other Speyeria species, it is expected to exhibit visual-based navigation to locate suitable habitat patches, though specific studies on this subspecies are lacking.
