Apodemia mormo mormo
Mormon Metalmark
Apodemia mormo mormo is a subspecies of metalmark butterfly in the family Riodinidae. It belongs to the genus Apodemia, a group of small butterflies commonly known as metalmarks due to their distinctive metallic wing markings. The subspecies epithet 'mormo' is shared with the species name, indicating this is the nominate subspecies. Like other members of Riodinidae, it is likely associated with specific host plants in its larval stage, though detailed biological information for this particular subspecies is limited in the provided sources.
Asterocampa celtis celtis
Eastern Hackberry Butterfly
Asterocampa celtis celtis is the nominate subspecies of the Hackberry Butterfly, a brush-footed butterfly in the family Nymphalidae. It is strongly associated with hackberry trees (Celtis spp.) throughout its life cycle, with larvae feeding exclusively on these host plants. The subspecies ranges across eastern North America, where it is a common and widespread resident of woodland edges and riparian corridors.
Athous rufiventris rufiventris
Athous rufiventris rufiventris is a subspecies of click beetle in the family Elateridae, first described by Eschscholtz in 1822. The nominate subspecies is characterized by its reddish-orange ventral coloration, a trait reflected in its species epithet. As a member of the genus Athous, it possesses the family's characteristic elongated body form and the ability to perform the 'click' mechanism for righting itself when overturned. The subspecies is part of a complex that includes additional subspecies with variable coloration and distribution patterns.
Cicindela decemnotata decemnotata
Badlands Tiger Beetle
Cicindela decemnotata decemnotata is the nominate subspecies of the Badlands Tiger Beetle, a western North American cicindelid occupying the northwestern Great Plains, northern Great Basin, and Rocky Mountains north to Yukon. This subspecies is part of a species complex characterized by green coloration with variable red markings on the head, pronotum, and elytra, along with variably developed white elytral markings. Molecular and morphological evidence supports the recognition of this and three other subspecies, with populations having undergone rapid phylogenetic radiation following glacial recession within the last 10,000 years.
Cicindela lengi lengi
Blowout Tiger Beetle
Cicindela lengi lengi is the nominate subspecies of the blowout tiger beetle, a tiger beetle restricted to dry sand habitats in the central and northern Great Plains of North America. It is distinguished from the superficially similar C. formosa by its narrower body form, longer and narrower labrum, and obliquely straight (rather than C-shaped) humeral marking. Adults are active from late summer into early fall, with peak activity in September. The subspecies is characterized by dark coloration on the underside of the thorax, unlike the coppery underside seen in the northern subspecies C. lengi versuta.
Cicindela parowana parowana
Dark Saltflat Tiger Beetle
Cicindela parowana parowana is a subspecies of tiger beetle in the family Carabidae, described by Wickham in 1905. It is one of the nominate subspecies of the Dark Saltflat Tiger Beetle, a species associated with saline or alkaline habitats. The subspecies occurs in western North America where it inhabits salt flat environments. Like other tiger beetles, it is a fast-running, visually-oriented predator.
Cicindelidia obsoleta obsoleta
Large Grassland Tiger Beetle
Cicindelidia obsoleta obsoleta, the Large Grassland Tiger Beetle, is a subspecies of large tiger beetle found in dry grassland habitats of the southwestern United States. Adults are active during summer months and are among the largest tiger beetles in their range. The nominate subspecies occurs from western Texas and eastern New Mexico northward into eastern Colorado, overlapping with related subspecies in some areas. It is distinguished from the disjunct Missouri/Arkansas population (subspecies vulturina) by its summer adult phenology and generally darker coloration with reduced elytral maculations.
Dicheirus dilatatus dilatatus
Dicheirus dilatatus dilatatus is a subspecies of ground beetle in the family Carabidae. It is native to North America and has been recorded in the United States. As a member of the subfamily Harpalinae and tribe Anisodactylini, it belongs to a diverse group of ground-dwelling beetles.
Dichelotarsus cavicollis cavicollis
Dichelotarsus cavicollis cavicollis is a subspecies of soldier beetle in the family Cantharidae. It belongs to a genus distributed primarily in the Southern Hemisphere, with most species recorded from South America. The nominate subspecies represents the typical form of the species. Like other cantharids, adults are likely active on vegetation and possess soft, flexible elytra.
Euphilotes enoptes enoptes
dotted blue
Euphilotes enoptes enoptes is the nominate subspecies of the dotted blue butterfly, a small lycaenid found in western North America. It belongs to a species complex with localized, patchy distributions tied to specific host plant communities. The subspecies is less studied than its federally endangered relative E. e. smithi, with most ecological research focusing on that coastal California population.
Metoponium abnorme abnorme
Metoponium abnorme abnorme is a subspecies of darkling beetle in the family Tenebrionidae, originally described by LeConte in 1851. The genus Metoponium contains species associated with arid and semi-arid regions of western North America. As a nominate subspecies, it represents the typical form of Metoponium abnorme. Published records for this taxon are sparse, with no observations documented in major biodiversity databases.
Sympetrum semicinctum semicinctum
Sympetrum semicinctum semicinctum is a subspecies of meadowhawk dragonfly in the family Libellulidae. As a member of the genus Sympetrum, it shares characteristics typical of meadowhawks, including relatively small size and late-season flight activity. The nominate subspecies designation indicates this is the type subspecies of the species Sympetrum semicinctum. Like other Sympetrum species, it undergoes incomplete metamorphosis with aquatic nymphal stages and aerial adult predation.
