Excavator: Ground. This species usually nests in large aggregations. R.C.L. Perkins (1919e) describes its nesting habits in Devon. According to him the very characteristic burrow entrances were scattered over three or four square metres of a large pasture field. The diameter of each appeared small for the size of the bee and the excavated spoil lay around the entrance, not heaped above it. On digging out a specimen it was found that the upper section of the main burrow was constricted and it was in this part that the female guarded her nest, her head exactly filling the entrance. So tight was the opening that a pollen laden female returning to her nest deposited a ring of pollen around the burrow mouth, this being accidentally scraped off as she entered. The large head and narrow, cylindrical form of he body are presumably adaptations for such a nesting habit.
This is a eusocial species, its biology being similar to that of Lasioglossum malachurum (E. Stoeckhert, 1923). Westrich (1989) briefly describes the form of the nest and reports that workers mated with males often take part in social egg-laying (polygyny). He further states that up to 10 gynes overwinter communally in the natal nest. The gynes are usually a little larger than the workers.
