Airora minuta
Airora minuta is a species of beetle in the family Trogossitidae. The genus Airora belongs to this family of predatory beetles commonly known as bark-gnawing beetles. Very little published information exists regarding this particular species. The family Trogossitidae comprises beetles that are typically found in association with dead or decaying wood, where they prey on other arthropods.
Calitys scabra
Calitys scabra is a species of beetle in the family Trogossitidae, originally described by Thunberg in 1784 under the basionym Hispa scabra. It belongs to a small family of predatory beetles commonly known as bark-gnawing beetles. The species has a Holarctic distribution with confirmed records from several Canadian provinces.
Corticotomus cylindricus
Corticotomus cylindricus is a species of beetle in the family Trogossitidae. The genus Corticotomus contains few described species, and C. cylindricus appears to be a rarely encountered species with limited documentation. Members of Trogossitidae are commonly known as bark-gnawing beetles.
Eronyxa pallida
Eronyxa pallida is a species of beetle in the family Lophocateridae (formerly placed in Trogossitidae), described by Motschulsky in 1863. It belongs to a family of predatory beetles commonly known as bark-gnawing beetles. The species has been documented in western North America, with confirmed records from British Columbia, Canada.
Euschaefferia hicoriae
Euschaefferia hicoriae is a species of beetle in the family Trogossitidae, a group commonly known as bark-gnawing beetles. The species is known from very few records, with only one documented observation on iNaturalist. Members of the genus Euschaefferia are poorly studied, and little is known about their biology or ecology. The specific epithet "hicoriae" suggests a possible association with hickory (Carya species), though this relationship remains unconfirmed.
Nemozoma punctulatum
Nemozoma punctulatum is a species of bark-gnawing beetle in the family Trogossitidae, described by Van Dyke in 1920. It is known from a small number of observations in British Columbia, Canada. Members of this family are generally associated with woody substrates and are predatory or feed on fungi.
Temnoscheila acuta
Temnoscheila acuta is a bark-gnawing beetle in the family Trogossitidae. The species was described by LeConte in 1858. It closely resembles Eleodes suturalis, a darkling beetle with which it shares size, coloration, and a reddish-brown sutural stripe on the elytra. Both species occur sympatrically in the Great Plains region. T. acuta averages larger than E. suturalis, approximately 30 mm versus under 26 mm.
Temnoscheila aerea
Temnoscheila aerea is a bark-gnawing beetle in the family Trogossitidae. The genus Temnoscheila is characterized by highly agile beetles that are usually at least slightly iridescent or metallic in appearance. This species is part of a family whose members are associated with dead or decaying wood, particularly on conifers. The specific epithet "aerea" suggests a bronze or coppery metallic coloration.
Temnoscheila chlorodia
green bark-gnawing beetle, green bark beetle, Pine Trogossitid Beetle
Temnoscheila chlorodia is a bark-gnawing beetle in the family Trogossitidae, known by common names including green bark-gnawing beetle and Pine Trogossitid Beetle. Adults are metallic green or blue predators that forage beneath bark of dead trees. The species occurs in western North America and shows bimodal adult activity in late spring and late summer. Both adults and larvae are predatory, hunting in decaying wood and associated with wood-boring insect nests and wood-decay fungi.
Temnoscheila omolopha
Temnoscheila omolopha is a species of bark-gnawing beetle in the family Trogossitidae. It belongs to a genus of beetles associated with dead and decaying wood, particularly on conifers. The species is rarely encountered in the field, with only six observations documented on iNaturalist, suggesting either genuine rarity or highly specialized habitat requirements that limit detection.
Temnoscheila virescens
Temnoscheila virescens is a predatory beetle in the family Trogossitidae, commonly known as bark-gnawing beetles. Research demonstrates that this species is attracted to cerambycid beetle pheromones, specifically 3-hydroxyhexan-2-one, with ethanol enhancing this attraction. This chemical eavesdropping behavior indicates a predator-prey relationship with longhorn beetles (Cerambycidae). The species belongs to a family whose members are typically associated with dead or dying wood habitats.
Temnoscheila yuccae
Temnoscheila yuccae is a species of bark-gnawing beetle in the family Trogossitidae. The genus Temnoscheila contains species associated with dead or dying wood, particularly conifers. Members of this genus share the characteristic convex, bullet-like body shape and bead-like antennae typical of the family. T. yuccae is distinguished from congeners by its association with yucca plants rather than conifers.
Tenebroides collaris
bark-gnawing beetle
Tenebroides collaris is a bark-gnawing beetle in the family Trogossitidae. New substantial distributional records have been documented for Montana, USA, and the species has also been recorded from Ontario, Canada. As a member of Trogossitidae, it is associated with bark habitats, though specific biological details remain poorly documented in available literature.
Tenebroides corticalis
Twisted Bark-gnawing Beetle
Tenebroides corticalis is a bark-gnawing beetle in the family Trogossitidae, known by the common name Twisted Bark-gnawing Beetle. The species was described by Melsheimer in 1844 and occurs in North America. As a member of Trogossitidae, it is associated with woody substrates, though specific ecological details remain limited in published sources.
Tenebroides crassicornis
A species of bark-gnawing beetle in the family Trogossitidae, described by Horn in 1862. Known from limited observations in western North America, with confirmed records from British Columbia. As with other members of Trogossitidae, this species is likely associated with decaying wood and fungal communities.
Tenebroides marginatus
Tenebroides marginatus is a species of beetle in the family Trogossitidae, commonly known as bark-gnawing beetles. The genus Tenebroides includes species associated with dead or decaying wood and bark habitats. Very limited information is available for this particular species.
Tenebroides nanus
Tenebroides nanus is a species of bark-gnawing beetle in the family Trogossitidae. The specific epithet "nanus" (Latin for "dwarf") suggests small body size relative to congeners. As a member of Trogossitidae, it likely inhabits forest environments where it feeds on fungi, decaying wood, or other organic matter associated with dead or dying trees. The genus Tenebroides contains numerous species primarily distributed across the Northern Hemisphere, with many species poorly studied due to their cryptic habits.
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.
