Dieunomia

Dieunomia is a genus of halictid bees in the family Halictidae. These bees are typically found in arid and semi-arid regions of North America. Dieunomia species are known for their oligolectic pollen foraging habits, meaning they specialize in collecting pollen from a limited number of plant species, often within the sunflower family (Asteraceae). They are important pollinators within their specific ecosystems. Characteristics of Dieunomia bees include small to medium size, dark coloration, and specific morphological features used to distinguish them from other bee genera. Their nests are typically constructed in the ground. Their presence and population health are important indicators of ecosystem health and floral resource availability.
