Aradus acutus
flat bug
Aradus acutus is a species of flat bug in the family Aradidae, first described by Thomas Say in 1832. It belongs to a group of insects commonly known as flat bugs due to their strongly dorsoventrally flattened bodies. The species is found in North America, though specific ecological details remain poorly documented in the available literature.
Aradus curticollis
Aradus curticollis is a species of flat bug in the family Aradidae, described by Bergroth in 1913. Like other members of the genus Aradus, it belongs to a group of true bugs commonly associated with dead wood habitats. The species is recorded from North America, though specific details about its biology and ecology remain poorly documented in available literature.
Aradus medioximus
Aradus medioximus is a species of flat bug in the family Aradidae, described by Parshley in 1921. The genus Aradus comprises bark-dwelling true bugs commonly associated with dead wood habitats. Species in this genus are characterized by their dorsoventrally flattened bodies, an adaptation for living under bark. As with other members of Aradidae, they are thought to feed on fungal hyphae and decaying organic matter, though specific details for A. medioximus remain poorly documented. The species is recorded from North America.
Aradus quadrilineatus
four-lined flat bug
Aradus quadrilineatus is a species of flat bug in the family Aradidae, described by Thomas Say in 1825. It is distributed across Central America and North America. As with other members of Aradidae, it is presumed to inhabit dead wood habitats, though specific ecological details for this species remain poorly documented.
Bitoma ornata
Bitoma ornata is a species of cylindrical bark beetle in the family Zopheridae. The species was described by LeConte in 1858. Like other members of its genus, it is associated with dead wood and bark habitats. The specific epithet "ornata" suggests some form of decorative or patterned appearance, though detailed descriptions of its morphology are not widely documented in available sources.
Chalcosyrphus satanicus
Chalcosyrphus satanicus is a hoverfly species in the family Syrphidae, first described by Bigot in 1884. Like other members of the genus Chalcosyrphus, this species exhibits morphological adaptations associated with dead wood habitats. The specific epithet "satanicus" places it among a small group of insects with devil-themed scientific names. The species occurs in North America, with records from Canada and the United States.
Colydium nigripenne
Colydium nigripenne is a species of cylindrical bark beetle first described by LeConte in 1863. It belongs to the family Zopheridae, a group of beetles commonly associated with dead or decaying wood. The species is documented from North America. Very few observations exist in public databases, with only seven records on iNaturalist.
Cryptorhynchinae
hidden-snout weevils
Cryptorhynchinae is a large subfamily of weevils (Curculionidae) comprising approximately 6,000 species. The subfamily is distinguished by a rostrum that folds backward between the fore coxae in repose, fitting within a protective channel on the mesoventrite. Molecular evidence supports its monophyly as an independent subfamily rather than inclusion within Molytinae. The group is most diverse in the Neotropics, Australia, and Oceania, with an evolutionary origin in the Late Cretaceous of South America.
Dromaeolus californicus
Dromaeolus californicus is a species of false click beetle in the family Eucnemidae, described by Bonvouloir in 1875. The species is known from western North America, with distribution records from British Columbia, Canada. Like other members of the family Eucnemidae, it belongs to the elateroid beetles and is characterized by the inability to produce the clicking sound typical of true click beetles (Elateridae). The genus Dromaeolus is part of a group of eucnemids often associated with decaying wood and forest habitats.
Hyporhagus punctulatus
opossum beetle
Hyporhagus punctulatus is a species of opossum beetle in the family Zopheridae, described by Thomson in 1860. The species is native to North America. Members of the genus Hyporhagus are commonly referred to as opossum beetles due to their defensive behavior of feigning death when disturbed. Like other zopherid beetles, they are typically found in association with dead or decaying wood.
Lasconotus pusillus
Lasconotus pusillus is a small beetle species in the family Zopheridae, first described by LeConte in 1863. It belongs to a genus of cylindrical bark beetles associated with dead or decaying wood. The species is known from North America, though detailed ecological information is limited.
Silvanoprus angusticollis
Silvanoprus angusticollis is a silvanid flat bark beetle (family Silvanidae) first described by Reitter in 1876. The species occurs in North America, including the Canadian province of Québec. Like other members of Silvanidae, it inhabits environments associated with dead or decaying wood and stored plant products. The genus Silvanoprus is distinguished from related genera by specific morphological features of the antennae and pronotum.
