Speyeria nokomis
Nokomis fritillary
Speyeria nokomis, the Nokomis fritillary, is a North American butterfly in the family Nymphalidae. The species has a highly specialized relationship with its host plant, with larvae feeding exclusively on northern bog violet (Viola nephrophylla). It is currently recognized with nine subspecies, including the imperiled Carson Valley silverpot butterfly (S. n. carsonensis), which has experienced significant population declines. Conservation efforts focus on habitat restoration through propagation of its obligate host plant.
