Euptoieta
fritillary butterflies
Euptoieta is a genus of fritillary butterflies in the subfamily Heliconiinae, distributed throughout the Neotropical region and extending northward into temperate North America. The genus includes approximately eight described species, with Euptoieta claudia (variegated fritillary) and Euptoieta hegesia (Mexican fritillary) being the most widely recognized. Members of this genus are characterized by their orange and black wing patterns and their ecological association with Viola (violet) species as larval host plants.
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.
