These bees have been observed to make nests in hard, compact soil, using cracks to enter the ground below.[3] Females will make solitary nests.[3] The female seeks out cracks in the ground, in which she digs a tunnel down to make her nest.[2][3] She will repeatedly thump the walls of the tunnel with her abdomen, to make them more compact.[3] 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.[2][3] Some larvae hibernate in a pupated state up to 2 years.[3] 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.[3] As one generation of emerging adults might die because of drought, the next generation might survive, giving the species more chance of survival.
The name Euherbstia, (From Herbst, German[4]) is a reference to the activity of these bees, which is in the months of October and November.[3] Males, and females that have yet to build a nest, sleep overnight in convenient cracks in the soil.[3] Foraging activity peaks around midday.[3]
No cuckoo bee species seem to target the nests of Euherbstia.[3]
