This bee's nest architecture is described by Sakagami and Michener (1962). From Sakagami and Michener (1962): 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. Nests are known from both flat ground and banks.
