Euphydryas anicia hermosa
Euphydryas anicia hermosa is a subspecies of checkerspot butterfly in the family Nymphalidae. The species Euphydryas anicia is currently placed in the genus Euphydryas, though some sources recognize it under the genus Occidryas. This subspecies was described by W.G. Wright in 1905. The broader species Euphydryas anicia is known as the Anicia checkerspot, with several recognized subspecies distributed across western North America.
Plebejus optilete
Cranberry Blue
Plebejus optilete, commonly known as the Cranberry Blue, is a montane lycaenid butterfly species found in European mountain systems. The species has a restricted distribution in Slovenia, limited to six separate sites on the crests of the western Pohorje Mountains. It is associated with silicate grasslands containing abundant Vaccinium species, which likely serve as larval host plants. Population monitoring indicates declining abundance across most sites, with habitat degradation from overgrazing, inappropriate land use, and tourism development posing significant threats.
Speyeria mormonia mormonia
Mormon Fritillary
Speyeria mormonia mormonia is a montane butterfly subspecies found in western North America. Research indicates adults exhibit compensatory feeding behavior to offset energy costs of increased flight activity. Females demonstrate higher early-life fecundity under conditions of abundant food resources, with metabolic rates declining with age. The subspecies shows sexual dimorphism in demographic parameters including survival patterns correlated with weather conditions.
