The sweat bee genus Lasioglossum is the largest of all bee genera, containing over seventeen hundred species in numerous subgenera worldwide. They are highly variable in size, colouration, and sculpture; among the more unusual variants, some are cleptoparasites, some are nocturnal, and some are oligolectic. Most Lasioglossum nest in the ground, but some species nest in rotten logs.

The term oligolecty is used in pollination ecology to refer to bees that exhibit a narrow, specialized preference for pollen sources, typically to a single genus of flowering plants. The preference may occasionally extend to multiple genera within a single plant family, or be as narrow as a single plant species.
