[1][2] These bees have been observed to make nests in hard, compact soil, using cracks to enter the ground below.

[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.

[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.

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.
