Augochlora aurifera
Auriferous Green Sweat Bee
Augochlora aurifera is a metallic green sweat bee in the family Halictidae, described by Cockerell in 1897. As a member of the tribe Augochlorini, it exhibits the characteristic bright metallic coloration common to this group. The species is distributed across North America and Middle America. Like other Augochlora species, it is presumed to be solitary or primitively social, though specific behavioral details for A. aurifera remain poorly documented compared to better-studied congeners such as Augochlora pura.
Augochlora pura mosieri
Augochlora pura mosieri is a subspecies of the solitary sweat bee Augochlora pura, described by Cockerell in 1922. As a member of the Halictidae family, it exhibits the metallic green coloration typical of the Augochlorini tribe. Like other Augochlora pura populations, it is solitary, nesting in rotting wood galleries rather than soil. The subspecies designation indicates geographic variation within the broader species range in eastern North America.
Augochlorella neglectula
sweat bee
Augochlorella neglectula is a metallic green sweat bee in the family Halictidae. It is one of sixteen recognized species in the genus Augochlorella, which is distributed across the New World. The species exhibits the bright metallic coloration typical of the tribe Augochlorini, making it visually similar to congeners and other augochlorine bees. Subspecific variation includes the coastal form A. neglectula maritima, though this has been synonymized with the nominate subspecies in some treatments.
Augochlorella nigrocyanea
Augochlorella nigrocyanea is a species of sweat bee in the family Halictidae, tribe Augochlorini. The genus Augochlorella contains several species of small, metallic bees that are difficult to distinguish from related genera Augochlora and Augochloropsis without microscopic examination. Members of this genus are known for their bright metallic green, blue-green, or occasionally brassy coloration. Some Augochlorella species exhibit communal nesting or primitively social behavior, with multiple females sharing nest entrances.
Augochlorella pomoniella
Peridot Sweat Bee
Augochlorella pomoniella is a small, metallic green sweat bee in the family Halictidae, commonly known as the Peridot Sweat Bee. It belongs to the tribe Augochlorini, a group of bright metallic bees that are frequently mistaken for cuckoo wasps due to their similar appearance. The species is distributed across North America and Middle America. Like other Augochlorella species, it is a ground-nesting bee that visits flowers for pollen and nectar.
Lasioglossum albipenne
white-winged metallic-sweat bee, white-winged sweat bee
Lasioglossum albipenne is a metallic sweat bee in the family Halictidae, commonly known as the white-winged metallic-sweat bee. It belongs to the subgenus Dialictus, a large and taxonomically challenging group of small bees. The species was originally described by Robertson in 1890 and has undergone taxonomic revision, with several synonymies resolved in recent Canadian treatments. Like other members of its genus, it is a ground-nesting bee and likely contributes to pollination in its native range.
Lasioglossum cattellae
A small metallic sweat bee in the subgenus Dialictus, originally described from the eastern United States. The species was previously known under the synonym Dialictus alternatus until synonymized by Gibbs (2010). Like other members of this large subgenus, it is a ground-nesting bee with likely solitary or weakly social behavior.
Lasioglossum laevissimum
Very Smooth Sweat Bee
Lasioglossum laevissimum is a small metallic sweat bee in the subgenus Dialictus, one of the most species-rich and taxonomically challenging groups of North American bees. The species was described by Smith in 1853 and has accumulated seven synonymies due to historical difficulties in distinguishing Dialictus species. It occurs in Canada and the northern United States, where it nests in soil and visits flowers for pollen and nectar. Like other Dialictus, it is likely a solitary or weakly social ground-nesting bee with females provisioning individual brood cells.
Lasioglossum leucocomum
Lasioglossum leucocomum is a small metallic sweat bee in the subgenus Dialictus, one of the largest and most taxonomically challenging bee genera in North America. The species was resurrected from synonymy in a 2010 revision of Canadian Dialictus, which recognized it as a valid species distinct from previously confused names. Like other Dialictus, it is a ground-nesting bee with variable social organization, ranging from solitary to small-colony sociality. The species contributes to pollination services in its native range.
Lasioglossum nigroviride
Black-and-green Metallic-Sweat bee, black-and-green dialictus sweat bee
Lasioglossum nigroviride is a small metallic sweat bee in the family Halictidae, placed in the subgenus Dialictus. The species was described by Graenicher in 1911 and is one of numerous metallic Lasioglossum species in North America. Halictus (Chloralictus) richardsoni Cockerell was synonymized with this species in Gibbs's 2010 revision of Canadian Dialictus. Like other members of this large genus, it is a ground-nesting bee with likely solitary or semi-social behavior.
Lasioglossum perpunctatum
Densely Punctured Sweat Bee
Lasioglossum perpunctatum is a metallic sweat bee in the subgenus Dialictus, one of the most diverse and commonly collected bee groups in North America. The species was originally described by Ellis in 1913 and has undergone taxonomic revision, with two former species (D. highlandicus and D. junaluskensis) now synonymized with it. Like other Dialictus, it exhibits varied social systems ranging from solitary to eusocial. As a member of the largest bee genus, it contributes to pollination services in its native range.
Lasioglossum versans
Friendless Sweat Bee
Lasioglossum versans is a species of sweat bee in the family Halictidae, subgenus Dialictus. It was described by Lovell in 1905 and is one of 84 metallic Dialictus species treated in the Canadian taxonomic revision. The species is known from North America with records from Vermont. Like other members of the large genus Lasioglossum, it is a ground-nesting bee with likely solitary or semi-social nesting biology.
Lasioglossum versatum
Experienced Sweat Bee
Lasioglossum versatum is a sweat bee species in the family Halictidae, subgenus Dialictus, native to North America. It was described by Robertson in 1902 and has undergone taxonomic revision, with three synonymies proposed in a 2010 Canadian revision. Like other Dialictus species, it is small and likely metallic, though specific ecological details remain poorly documented. The species contributes to the diverse assemblage of Lasioglossum bees that dominate many North American bee surveys.
Osmia aglaia
Oregon berry bee
Osmia aglaia is a solitary mason bee native to the western United States. It is commonly known as the Oregon berry bee due to its specialized role as a pollinator of brambles, particularly raspberries and blackberries. The species exhibits metallic coloration and nests in pre-existing wood tunnels. Adults are active in late spring, coinciding with Rubus bloom periods.
