This bee's nest architecture is described by Sakagami and Michener (1962). From Sakagami and Michener (1962): Nest architecture is Type IIIb: Lateral burrows are very short or absent such that cells are almost attached to the burrow walls at a right angle. The cells are not spatially concentrated in any part of the burrow. Or nest architecture is Type IIIc: Lateral burrows are very short or absent such that cells are almost attached to the burrow walls at a right angle. The cells are not spatially concentrated in one part of the burrow, and project from the main burrow radially. Flat ground is the only or typical substrate used for nesting. Nests, but not cells, are re-used by subsequent generations.
