Catonia picta
Catonia picta is a planthopper species in the family Achilidae, first described by Van Duzee in 1908. The species belongs to the subfamily Myconinae and tribe Plectoderini. It is a member of the diverse Hemipteran fauna of eastern North America, with documented records across the southeastern and mid-Atlantic United States. As with other achilid planthoppers, it is associated with forest and woodland habitats where it feeds on fungal hyphae.
Eustrophus tomentosus
Eustrophus tomentosus is a species of polypore fungus beetle in the family Tetratomidae, found in North America. It is characterized by abundant yellowish-orange setae covering the elytra surface. The species can be distinguished from related genera by the absence of a prothoracic episternal transverse suture. As a member of the polypore fungus beetles, it is associated with bracket fungi in forested habitats.
Himacerus
damsel bugs
Himacerus is a genus of predatory damsel bugs in the family Nabidae, subfamily Nabinae. The genus includes several Eurasian species, with Himacerus apterus being the most studied. These bugs are generalist predators that inhabit forest edges, meadows, and open woodlands. Some species have been introduced to North America, notably H. apterus in eastern Canada.
Pediacus hesperoglaber
Pediacus hesperoglaber is a species of flat bark beetle described from western North America in 2004. It belongs to the family Cucujidae, a group of elongate beetles associated with decaying wood and fungal habitats. The species epithet 'hesperoglaber' references its western distribution and smooth appearance. Like other members of the genus, it likely inhabits forest environments where it occurs under bark or in wood-decay communities.
Scaphidium
shining fungus beetles
Scaphidium is a genus of shining fungus beetles in the family Staphylinidae. Members are small beetles with compact, rounded bodies and short elytra that leave much of the abdomen exposed. The genus contains approximately 62 described species distributed across multiple continents.
Scaphinotus bilobus
Bilobed Snail-eating Beetle
Scaphinotus bilobus, commonly known as the bilobed snail-eating beetle, is a species of ground beetle in the family Carabidae. It is a brachypterous (short-winged), nocturnal predator specialized in feeding on snails. The species occurs across a broad swath of North America, ranging from eastern Canada through the Great Lakes region and into the north-central United States.
Scaphinotus elevatus
eastern snail eater, Large-thoraxed Snail-eating Beetle, elevated thorax snail-eating beetle
Scaphinotus elevatus is a species of ground beetle in the family Carabidae, commonly known as the eastern snail eater. It is one of the larger carabid beetles in North America, with most individuals measuring at least 15 mm in length. The species belongs to the Carabinae subfamily, which includes the so-called 'caterpillar hunters' and 'snail hunters'—giant ground beetles closely related to tiger beetles. Six subspecies are recognized, distributed across eastern, central, and southwestern North America.
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 riversi
Rivers' snail-eating beetle
Scaphinotus riversi, commonly known as Rivers' snail-eating beetle, is a flightless ground beetle in the family Carabidae. The species is endemic to California, where it inhabits forested environments. Adults are brachypterous (short-winged) and exhibit nocturnal activity patterns. As a member of the genus Scaphinotus, it is presumed to be a molluscivore, feeding on snails and slugs, though direct dietary observations for this specific species are not documented.
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.
Thalycra concolor
Thalycra concolor is a species of sap-feeding beetle in the family Nitidulidae. The species was described by LeConte in 1850 and is known from western and central North America. Like other members of the genus Thalycra, it is attracted to lights at night and associated with fermenting plant materials.
