These bees have been observed to make nests in hard, compact soil, using cracks to enter the ground below. Females will make solitary nests. The female seeks out cracks in the ground, in which she digs a tunnel down to make her nest. She will repeatedly thump the walls of the tunnel with her abdomen, to make them more compact. Like all mining bees, they will create cells which they fill with pollen and eggs, closing them off until the larvae pupate and emerge the next year. Some larvae hibernate in a pupated state up to 2 years. This is probably because these bees live in an arid climate, where it is uncertain whether it will rain enough in a year to sustain the plants they need for food. As one generation of emerging adults might die because of drought, the next generation might survive, giving the species more chance of survival.
