Euphydryas anicia cloudcrofti
Sacramento Mountains Checkerspot
Euphydryas anicia cloudcrofti is a subspecies of checkerspot butterfly endemic to the Sacramento Mountains of New Mexico. It is currently proposed for listing under the Endangered Species Act. The subspecies is known from high-elevation habitats and has been the subject of research on parasitoid interactions, specifically with Cotesia wasps (Braconidae). Its restricted range and specific habitat requirements contribute to its conservation concern.
Speyeria idalia
regal fritillary
Speyeria idalia, commonly known as the regal fritillary, is a prairie-obligate butterfly species native to North America. The species has experienced severe population declines, with abundance and occupied range reduced by over 99% due to tallgrass prairie loss and degradation. Populations are now largely restricted to isolated remnant prairie patches, primarily in the Flint Hills ecoregion of Kansas and scattered sites across the Midwest. The species is under consideration for protection under the Endangered Species Act and serves as an indicator for grassland ecosystem health.
