One of four small, metallic Lasioglossum species. Males are easily distinguished from the others by the pale yellow mid and hind tarsi. Females resemble L. morio but are stockier with a shinier thorax and propodeum, and lack minute transverse ridges on the apical depression of tergite 2.

Found in a range of habitats foraging on a wide variety of flowers.

Females may be found between May and October, males between July and September. As with all Lasioglossum in Britain, only mated females hibernate.

A possible host of Sphecodes geoffrellus.

This is a widespread and locally common species.

Status in Leicestershire and Rutland not known.
