The genus Halictus is a large assemblage of bee species in the family Halictidae. The genus is divided into 15 subgenera, containing well over 300 species, primarily in the Northern Hemisphere (a few species occur in South America and Africa). Most species are black or dark brown, sometimes metallic greenish-tinted, with apical whitish abdominal bands (the related genus Lasioglossum, which is otherwise often similar in appearance, has the abdominal hair bands located basally, not apically).
