Scaphinotus schwarzi
Schwarz's snail-eating beetle
Scaphinotus schwarzi is a species of ground beetle in the family Carabidae, commonly known as Schwarz's snail-eating beetle. It is one of the "snail hunter" beetles in the nominate subfamily Carabinae, characterized by large size and specialized mandibular morphology adapted for predation on snails. The species is known from forest habitats in North Carolina. Adults are brachypterous (short-winged) and nocturnal.
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.
Scaphinotus subtilis
Slender Snail-eating Beetle
Scaphinotus subtilis, commonly known as the slender snail-eating beetle, is a species of ground beetle in the family Carabidae. It is endemic to California in North America. Adults are brachypterous (short-winged) and nocturnal, and the species is typically found near bodies of water.
Scaphinotus tenuis
Thin Snail-eating Beetle
Scaphinotus tenuis, commonly known as the thin snail-eating beetle, is a species of ground beetle in the family Carabidae. It is found in North Carolina, USA, where it inhabits forest environments. Adults are brachypterous (short-winged) and nocturnal in their activity pattern.
Scaphinotus tricarinatus
Three-ridged Snail-eating Beetle
Scaphinotus tricarinatus, the three-ridged snail-eating beetle, is a species of ground beetle in the family Carabidae. It is a member of the Carabinae subfamily and Cychrini tribe, placing it among the so-called 'snail-eating' beetles. The species is found in the southeastern United States, specifically in North Carolina, South Carolina, and Tennessee. Adults are brachypterous (short-winged) and nocturnal, inhabiting forested areas often in ravines along streams.
Scaphinotus velutinus
Velvet Snail-eating Beetle
Scaphinotus velutinus, commonly known as the velvet snail-eating beetle, is a flightless ground beetle species in the family Carabidae. It is endemic to western North America, with confirmed records from California and Oregon. The species inhabits coniferous forest ecosystems and is characterized by reduced wings (brachyptery). As a member of the genus Scaphinotus, it is specialized for predation on terrestrial snails.
Scaphinotus ventricosus
potbellied snail-eating beetle, pot-bellied snail-eating beetle
Scaphinotus ventricosus is a species of ground beetle in the family Carabidae, commonly known as the potbellied snail-eating beetle. It is native to western North America, with documented occurrence in California and Oregon. Adults are distinctive among ground beetles for their brachypterous (short-winged) condition, which renders them flightless. The species exhibits gregarious and nocturnal behavior. It inhabits deciduous forests and poison-oak thickets, where it presumably feeds on snails as suggested by its common name and the feeding habits of related species in the genus.
Scaphinotus violaceus
violet snail-eating beetle
Scaphinotus violaceus is a flightless ground beetle native to the southeastern United States. Adults are brachypterous and nocturnal, inhabiting deciduous and mixed forests. The species is one of several snail-eating beetles in the genus Scaphinotus.
Sepedophilus brachypterus
Sepedophilus brachypterus is a rove beetle described by Campbell in 1976. It belongs to the subfamily Tachyporinae, a group often associated with fungal fruiting bodies and decaying organic matter. The species is characterized by reduced wings (brachyptery), as indicated by its specific epithet. It is known from eastern North America with a range extending from Canada through the eastern and central United States.
Slaterobius chisos
Slaterobius chisos is a species of seed bug in the family Rhyparochromidae, described by Slater & Sweet in 1993. It is known from the Chisos Mountains region of western Texas, a rugged desert mountain range within Big Bend National Park. The species belongs to a genus of ground-dwelling seed bugs associated with arid and semi-arid habitats. Like other members of Rhyparochromidae, it is presumed to feed on seeds, though specific ecological details remain poorly documented. The species is rarely collected and appears to have a restricted geographic range.
Sphaeroderus bicarinatus
Two-ridged False Snail-eating Beetle
Sphaeroderus bicarinatus is a ground beetle in the family Carabidae, commonly known as the two-ridged false snail-eating beetle. It is a brachypterous, mostly nocturnal predator found in forested habitats of the southeastern United States. Despite its common name, it has been observed preying on snails as well as Lepidoptera caterpillars and pupae.
Sphaeroderus indianae
Indiana False Snail-eating Beetle
Sphaeroderus indianae is a flightless ground beetle in the tribe Cychrini, known from deciduous forests of the eastern United States. Adults possess reduced wings (brachypterous), restricting dispersal and contributing to its patchy distribution. The species is one of several North American Sphaeroderus with limited range and specific habitat requirements.
