Scaphinotus ridingsii monongahelae
Scaphinotus ridingsii monongahelae is a subspecies of ground beetle in the family Carabidae, described by Leng in 1917. It belongs to the genus Scaphinotus, commonly known as snail-eating beetles or snail hunters, which are specialized predators of terrestrial snails. The subspecies epithet "monongahelae" suggests an association with the Monongahela River region of the eastern United States. Like other members of the tribe Cychrini, this beetle possesses enlarged, asymmetrical mandibles adapted for extracting snails from their shells.
Tetropium velutinum
Western Larch Borer
Tetropium velutinum, commonly known as the Western Larch Borer, is a species of longhorn beetle in the family Cerambycidae. It was described by John Lawrence LeConte in 1869. The species is associated with coniferous forests of western North America, particularly with larch trees (Larix spp.) which serve as its larval host. Like other members of the genus Tetropium, adults are typically attracted to recently dead or dying host trees.
Thymalus marginicollis
Bark-gnawing Beetle
Thymalus marginicollis is a species of bark-gnawing beetle in the family Thymalidae (sometimes historically placed in Trogossitidae). The species was described by Chevrolat in 1842 and occurs across much of Canada, with records from Alberta, British Columbia, Manitoba, New Brunswick, and Newfoundland. As a member of Thymalidae, it belongs to a small family of predatory beetles associated with woody substrates.
Trichochrous ferrugineus
Trichochrous ferrugineus is a species of false click beetle in the family Eucnemidae, a group of saproxylic beetles associated with decaying wood. The genus Trichochrous comprises small to medium-sized beetles characterized by their elongated bodies and reduced or non-functional clicking mechanism compared to true click beetles (Elateridae). Species in this genus are typically found in forested habitats where they develop in dead or dying hardwoods.
Uloma
Uloma is a genus of darkling beetles in the family Tenebrionidae comprising more than 200 species and subspecies worldwide. The genus is particularly diverse in China, with at least 37 recorded species. Immature stages have been described for few species, revealing oligopod larvae and exarate pupae with sexual dimorphism in some species. Members are primarily associated with decaying wood in forest habitats.
Uloma mentalis
Uloma mentalis is a darkling beetle species in the family Tenebrionidae, described by George Henry Horn in 1870. It belongs to the genus Uloma, a group of small to medium-sized beetles associated with decaying wood and forest floor habitats. The species is known from limited observations in North America, with confirmed records from Ontario, Canada. As with many tenebrionid beetles, its biology is poorly documented in the scientific literature.
Xylopinus aenescens
Xylopinus aenescens is a species of darkling beetle in the family Tenebrionidae, first described by John Lawrence LeConte in 1866. It belongs to a genus of beetles associated with decaying wood and forest habitats. Records indicate it occurs in eastern Canada, specifically New Brunswick, Ontario, and Quebec. As a member of Tenebrionidae, it likely contributes to nutrient cycling through decomposition processes, though specific ecological studies on this species appear limited.
