Nomiinae
Guides
Dieunomia
Dieunomia is a genus of sweat bees in the family Halictidae, containing approximately nine described species. These bees are among the largest in their family, second only to the genus Nomia. They are relatively uncommon and exhibit specialized ecological relationships with their pollen sources.
Dieunomia heteropoda
Giant Sweat Bee
Dieunomia heteropoda is a large sweat bee in the family Halictidae, commonly known as the Giant Sweat Bee. It occurs in Central America and North America. The species nests in aggregations in hard-packed soil, with males exhibiting patrolling and digging behaviors to locate females at nest entrances. Two subspecies are recognized: D. h. heteropoda and D. h. kirbii.
Dieunomia nevadensis angelesia
Nevada nomia
Dieunomia nevadensis angelesia is a subspecies of sweat bee in the family Halictidae, originally described by Cockerell in 1910 as a form of Nomia nevadensis. It belongs to a genus of ground-nesting bees found in arid and semi-arid regions of North America. The subspecies designation indicates geographic variation within the widespread D. nevadensis species complex.
Dieunomia nevadensis bakeri
Baker's Nomia
Baker's Nomia is a subspecies of the Nevada nomia, a sweat bee in the family Halictidae. It was described by Cockerell in 1898 and is distinguished from the nominate subspecies by morphological characteristics. The subspecies occurs in western North America, where it is associated with alkali and saline habitats. Like other Dieunomia species, it is a ground-nesting bee with specialized ecological requirements.
Nomia angustitibialis
Canyon Nomia
Nomia angustitibialis is a species of ground-nesting bee in the family Halictidae, described by Ribble in 1965. The species is known from Middle America and North America. As a member of the genus Nomia, it shares the group's characteristic nesting biology in soil, though specific details of its ecology remain poorly documented compared to the well-studied congener Nomia melanderi.
