The nesting biology was described by Hicks (1929), who studied a nest deep in the ground among dense plants at the foot of a hill in California. The nest size was large; Hicks estimated that the nest contained 458 bees at the time of excavation (324 workers, 81 gynes, and 53 males) (Hicks 1929). The nest was located at the end of an approximately 6 foot long tunnel, approximately 3 feet below the surface (Hicks 1929).
