Nesting biology
This mining bee is thought to be primitively eusocial; early accounts of a solitary life cycle are now considered incorrect. Nests are excavated in horizontal ground which is usually sparsely vegetated or with a short sward. The burrow is vertical or nearly so, occasionally branched, with sessile cells opening off the main shaft of the nest. The foundress female constructs 6-9 horizontal cells off a short tunnel in the spring, of which 2 or 3 may produce males, the remainder producing workers. Many of these workers mate but do not undergo ovarian development. The second brood produces males and females which mate and then the latter hibernate. There are accounts of foundresses hibernating for a second winter.

Flowers visited
A wide range of flowers are visited for nectar.
