Argoporis costipennis
Argoporis costipennis is a species of darkling beetle in the family Tenebrionidae, originally described by LeConte in 1851. It belongs to the genus Argoporis, which comprises flightless beetles endemic to western North America. The species is recorded from Mexico (MX) and has been documented through 17 iNaturalist observations as of the available data. Like other members of its genus, it is likely adapted to arid or semi-arid environments typical of the region.
Scaphinotus interruptus
Ménétriés' snail-eating beetle, Menetries' Snail-eating Beetle
Scaphinotus interruptus is a species of ground beetle in the tribe Cychrini, commonly known as Ménétriés' snail-eating beetle. Adults are flightless due to reduced wings (brachyptery) and are specialized predators of terrestrial snails. The species is endemic to mountainous regions of the western United States, specifically California and Oregon.
Scaphinotus obliquus
Oblique Snail-eating Beetle
Scaphinotus obliquus is a large ground beetle in the family Carabidae, commonly known as the oblique snail-eating beetle. It belongs to the Carabinae subfamily, which includes specialized snail-hunting beetles characterized by their elongated jaws adapted for extracting snails from shells. Adults are brachypterous (short-winged), rendering them flightless. The species occurs in forested regions of California and Oregon.
Scaphinotus striatopunctatus
Pore-winged Snail-eating Beetle
A species of ground beetle in the family Carabidae, commonly known as the pore-winged snail-eating beetle. It is native to California in western North America, where it inhabits deciduous forests, canyons, and grassy knolls. Adults are distinctive for being brachypterous (short-winged), gregarious, and nocturnal in their activity patterns.
Stenomorpha horrida
Stenomorpha horrida is a species of darkling beetle in the family Tenebrionidae, tribe Asidini. First described by Champion in 1892, this flightless beetle belongs to a large genus historically comprising 88 species with limited modern taxonomic revision until recent work by Fran Keller and colleagues. The species is known from Mexico, though specific habitat and ecological details remain poorly documented in published literature. Like other Stenomorpha species, it likely inhabits arid or semi-arid environments given the genus's association with such habitats.
Stenomorpha wickhami
Stenomorpha wickhami is a darkling beetle species in the family Tenebrionidae, transferred into the genus Stenomorpha from its original combination by Horn. It belongs to the furcata species group, a newly recognized informal grouping within Stenomorpha established to accommodate this species and three related taxa including the type species S. furcata, S. roosevelti, and S. granicollis. The species is native to the southwestern United States, specifically southern Arizona. As a member of the Asidini tribe, it shares the general characteristics of flightless or weakly flighted desert-dwelling tenebrionids, though specific biological details for this species remain poorly documented.
Trichoton sordidum
Trichoton sordidum is a small, flightless darkling beetle (Tenebrionidae) native to the Sonoran Desert borderlands of southern Arizona and northern Mexico. The species exhibits sophisticated behavioral thermoregulation, including photonegativity and temperature-dependent activity patterns. Under resource limitation or environmental stress, individuals form adhesive aggregations or physical clumps of 2–10 beetles as a threat evasion mechanism. Dispersal follows cohesive patterns consistent with Minimum Risk Distribution models.
