Euphydryas anicia
Anicia checkerspot, Sacramento Mountains checkerspot
Euphydryas anicia is a checkerspot ( ) to the southwestern United States. The is represented by several , including E. a. howlandi and E. a. cloudcrofti, the latter being a rare, localized form to the Sacramento Mountains of New Mexico. The subspecies E. a. cloudcrofti has been proposed for listing under the due to its extremely restricted range and vulnerability to changes. Checkerspot butterflies in this are typically associated with specific plants and occupy distinct elevational zones.

Identification
Distinguished from other Euphydryas by geographic location and, in the case of E. a. cloudcrofti, by subtle differences in pattern and coloration compared to nominate E. anicia. The E. a. cloudcrofti is known only from high-elevation areas in the Sacramento Mountains of New Mexico, making location a identification feature. Separation from E. editha and other western checkerspots requires examination of or molecular analysis.
Appearance
-sized with orange and black checkered pattern typical of the Euphydryas. The exact coloration and pattern intensity varies among . E. a. cloudcrofti exhibits distinctive markings that distinguish it from other . Wingspan and detailed color patterns are not explicitly documented in available sources.
Habitat
Montane and subalpine zones, particularly in coniferous forest openings and meadows. E. a. cloudcrofti is specifically associated with high-elevation (approximately 9000 feet) in the Sacramento Mountains of New Mexico, where its larval plants occur in open areas within pine and mixed-conifer forest.
Distribution
Southwestern United States, with different occupying distinct ranges. The nominate subspecies occurs in broader areas of the Southwest, while E. a. cloudcrofti is restricted to the Sacramento Mountains in Otero County, New Mexico. E. a. howlandi has a separate, more northern distribution.
Seasonality
are active during summer months. Specific period varies by and elevation, with higher-elevation emerging later in the season.
Diet
feed on specific plants; visit flowers for nectar. The exact larval host plants for E. a. cloudcrofti are not explicitly documented in available sources, though other Euphydryas typically use plants in the Scrophulariaceae or Orobanchaceae.
Host Associations

More Details
Conservation status
The E. a. cloudcrofti is currently proposed for listing under the U.S. . A small protected area with caged food plots has been established in the Sacramento Mountains to support the . The subspecies' extremely limited range makes it vulnerable to climate change, alteration, and events.
Research access restrictions
Due to concerns, researchers must obtain permission to access sites where E. a. cloudcrofti occurs. One source document notes that a Forest Service required assurances that observers were not before revealing the location of protected food plots.
