Amara conflata
Amara conflata is a ground beetle species in the family Carabidae, described by John Lawrence LeConte in 1855. It belongs to the large genus Amara, which comprises numerous species of small to medium-sized carabid beetles distributed primarily in the Northern Hemisphere. The species occurs in North America, with documented records from Canada and the United States.
Amara farcta
Amara farcta is a ground beetle species in the family Carabidae, described by John Lawrence LeConte in 1855. It belongs to the large genus Amara, which contains numerous species of small to medium-sized ground beetles found primarily in the Northern Hemisphere. The species is recorded from North America, specifically from Canada and the United States.
Berosus aculeatus
Berosus aculeatus is a species of hydrophilid beetle first described by John Lawrence LeConte in 1855. It is native to the eastern United States and Cuba, with records spanning from Florida to New England and west to Iowa and Wisconsin. The species is distinguished by its prolonged elytral apices—a diagnostic morphological feature. Like other members of the genus Berosus, it is associated with aquatic or semi-aquatic habitats, though specific ecological details remain poorly documented.
Cymbiodyta bifida
Cymbiodyta bifida is a species of water scavenger beetle in the family Hydrophilidae. It belongs to the genus Cymbiodyta, which comprises aquatic beetles typically found in freshwater habitats. The species was described by John Lawrence LeConte in 1855 and is known from eastern North America, with records from Canada and the United States. Like other members of its family, it is presumed to inhabit aquatic or semi-aquatic environments where it contributes to nutrient cycling through scavenging behavior.
Elonus basalis
ant-like leaf beetle
Elonus basalis is a species of ant-like leaf beetle in the family Aderidae, first described by LeConte in 1855. The species is distributed across North America, with records from Canada (Ontario, Québec) and the northeastern United States (Vermont). As a member of Aderidae, it exhibits the characteristic compact body form and ant-like appearance typical of this family of small beetles.
Gymnochthebius fossatus
Gymnochthebius fossatus is a species of minute moss beetle in the family Hydraenidae, first described by LeConte in 1855. It is one of the smallest beetles in North America, with adults typically measuring less than 2 mm in length. The species has a broad geographic distribution spanning the Caribbean Sea, Central America, North America, and South America. As a member of Hydraenidae, it belongs to a family of beetles commonly known as moss beetles or minute moss beetles, which are primarily associated with moist microhabitats.
Hydrochus callosus
Hydrochus callosus is a species of water scavenger beetle in the family Hydrochidae, first described by John Lawrence LeConte in 1855. The species is found in the southeastern United States, with records from Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, South Carolina, and Texas. Hydrochidae are small aquatic beetles typically associated with freshwater habitats.
Hydrochus simplex
Hydrochus simplex is a small water scavenger beetle in the family Hydrochidae, a group sometimes treated as a subfamily within Hydrophilidae. The species was described by John Lawrence LeConte in 1855 and is documented from the southeastern United States and the Bahamas. Like other hydrochids, it occupies aquatic or semi-aquatic habitats.
Hygrotus nubilus
Hygrotus nubilus is a diving beetle in the family Dytiscidae, first described by John Lawrence LeConte in 1855. Like other members of the genus, this species is associated with freshwater aquatic habitats. The genus Hygrotus is widely distributed across North America and includes numerous species of small to medium-sized diving beetles.
Hygrotus patruelis
Hygrotus patruelis is a species of diving beetle in the family Dytiscidae, first described by John Lawrence LeConte in 1855. It belongs to the genus Hygrotus, a group of small to medium-sized predaceous diving beetles commonly found in aquatic habitats. The species is recorded from North America. Like other dytiscids, it is adapted to underwater life with specialized respiratory structures.
Limnohydrobius tumidus
Limnohydrobius tumidus is a species of water scavenger beetle in the family Hydrophilidae, described by John Lawrence LeConte in 1855. It is a small aquatic beetle distributed across the eastern and central United States. The species belongs to the tribe Hydrobiusini, which includes aquatic beetles associated with freshwater habitats. Records indicate it has been collected from Maine to Florida and west to Illinois and Indiana.
Monotoma producta
root-eating beetle
Monotoma producta is a species of small beetle in the family Monotomidae, commonly referred to as root-eating beetles. The species was described by John Lawrence LeConte in 1855 and is known to occur in North America, with documented records from Canada including New Brunswick, Nova Scotia, and Prince Edward Island. Like other members of Monotomidae, it is associated with decaying plant material and fungal environments. The species remains poorly documented in scientific literature beyond basic taxonomic and distributional records.
Nematoplus collaris
Nematoplus collaris is a species of false longhorn beetle in the family Stenotrachelidae. It is known from eastern North America, with records from New Brunswick, Ontario, and Québec in Canada. The species was described by John Lawrence LeConte in 1855. Very little published information exists regarding its biology, habitat preferences, or ecology.
Oosternum costatum
Oosternum costatum is a species of water scavenger beetle in the family Hydrophilidae. It is a small beetle found in North America, with records from the eastern and central United States and Mexico. The species was described by John Lawrence LeConte in 1855.
Tropisternus sublaevis
Tropisternus sublaevis is a species of water scavenger beetle in the family Hydrophilidae. The species was described by John Lawrence LeConte in 1855. It is distributed across western and central North America, with records from the United States and Mexico. The species belongs to the subgenus Tropisternus (Tropisternus) and has been subject to some taxonomic confusion, with a later homonym described by Blatchley in 1910.
