Anapleus marginatus
clown beetle
Anapleus marginatus is a species of clown beetle in the family Histeridae, first described by J.L. LeConte in 1853. The species is found in North America, with confirmed records from multiple U.S. states including Arizona, Illinois, Kansas, Oklahoma, and Texas. As a member of the Histeridae family, it belongs to a group of beetles commonly known as clown beetles or hister beetles, which are typically associated with decaying organic matter and are known for their compact, oval body shape and clubbed antennae.
Anaspis atrata
Black False Flower Beetle
Anaspis atrata is a species of false flower beetle in the family Scraptiidae, described by Champion in 1891. It is known from North America, with records from Canada (Alberta, British Columbia, Saskatchewan) and the United States. The common name "Black False Flower Beetle" refers to its dark coloration. Like other members of Scraptiidae, it belongs to a group sometimes treated as a subfamily of Melyridae (soft-winged flower beetles).
Ariotus luteolus
Ariotus luteolus is a species of ant-like leaf beetle in the family Aderidae, first described by Casey in 1895. It is found in North America. Members of this family are commonly known as ant-like leaf beetles due to their resemblance to ants in morphology and behavior. The species epithet "luteolus" refers to a yellowish or golden coloration.
Barilepis grisea
flower weevil
Barilepis grisea is a species of flower weevil in the beetle family Curculionidae, first described by Casey in 1920. The species is provisionally accepted in taxonomic databases and is known to occur in North America. As a member of the Curculionidae, it possesses the characteristic elongated snout (rostrum) typical of weevils.
Barilepton quadricolle
flower weevil
Barilepton quadricolle is a species of flower weevil in the beetle family Curculionidae. It was described by LeConte in 1876 and is found in North America. As a member of Curculionidae, it possesses the characteristic elongated snout (rostrum) typical of weevils. The genus Barilepton is a small group within the diverse flower weevil assemblage.
Bassareus mammifer
Red-Banded Bassar
Bassareus mammifer is a case-bearing leaf beetle in the family Chrysomelidae, commonly known as the Red-Banded Bassar. The species is characterized by its distinctive red banding pattern and is found across North America, with documented records from Canada and the United States. As a member of the Cryptocephalinae subfamily, larvae construct protective cases from fecal material and shed exoskeletons.
Botrodus estriatus
Botrodus estriatus is a small beetle species in the family Murmidiidae, a group of minute fungus beetles. The species was first described by Thomas L. Casey in 1890. GBIF currently lists this name as a synonym of Botrodus championi. Records indicate presence in North America.
Branchus
Branchus is a genus of darkling beetles in the family Tenebrionidae, subfamily Pimeliinae, and tribe Branchini. The genus was established by John Lawrence LeConte in 1862. It is placed within the speciose superfamily Tenebrionoidea, which includes many arid-adapted beetle lineages. The genus name derives from Greek mythology, though this etymological connection has no biological significance.
Dolerosomus silaceus
Siliceous Click Beetle
Dolerosomus silaceus is a click beetle in the family Elateridae, commonly known as the Siliceous Click Beetle. The species was described by Thomas Say in 1825 and is native to northeastern North America. It is a moderately well-documented species with over 300 citizen science observations recorded on iNaturalist.

false jewel beetle
Dystaxia murrayi is a species of false jewel beetle in the family Schizopodidae, described by LeConte in 1866. It is found in North America. The species belongs to a small family of beetles historically associated with jewel beetles (Buprestidae) but now recognized as a distinct lineage within the superfamily Buprestoidea. Very little is known about its biology or ecology.
Ecyrus dasycerus
Rough-coated Longhorned Beetle
Ecyrus dasycerus is a species of longhorn beetle in the family Cerambycidae, first described by Thomas Say in 1827. It is known from North America, with records from the United States and Mexico. The species exhibits two recognized subspecies: the nominate E. d. dasycerus and E. d. floridanus described by Linsley in 1935. Like other members of the subfamily Lamiinae, it is a wood-associated beetle whose larvae develop in dead or dying woody plants.

cyanipennis
Eumecomera cyanipennis is a species of false blister beetle in the family Oedemeridae. The species was described by Horn in 1870. It occurs in North America. The specific epithet cyanipennis refers to blue-colored wings, a characteristic feature of this species.
Euparius lugubris
Black and White Fungus Weevil
Euparius lugubris is a species of fungus weevil in the beetle family Anthribidae. It is found in North America, where it has been documented in at least 35 observations. The species was described by Olivier in 1800 and is commonly known as the Black and White Fungus Weevil.
Haliplus pantherinus
Haliplus pantherinus is a species of crawling water beetle in the family Haliplidae. It is known from North America, with confirmed records from Canada (New Brunswick, Nova Scotia) and the United States. As a member of Haliplidae, it is associated with aquatic or semi-aquatic habitats. The species was described by Aubé in 1838.
Listronotus tuberosus
Listronotus tuberosus is an underwater weevil in the family Curculionidae, distinguished from related species by its aquatic habitat. It is found in North America, with records from Canada including Manitoba, New Brunswick, Ontario, and Québec. The species was described by J.L. LeConte in 1876. Very little is known about its biology, ecology, or life history.
