This investigation started with the discovery of numerous Hesperapis regularis (Cresson) adults in May 1955, by P. F. Torchio and D. W. Ribble, within a restricted area near the Arroyo Seco Campground, Monterey Co., California. During the ensuing years the authors have made observations on the general activity around the nesting area, the sleeping habits, burrow and cell construction, flower relationships, and mating attempts. In addition larvae were collected for study and comparisons made with the larval description of H. ruficeps (Ashmead) (Michener 1953).
