Once a nest is found, studies show that Nomada females assess their hosts nests based on three guiding principles: 1) vulnerability and quality of the host cell, 2) threat of a maternal host's presence, 3) competition with other Nomada bees.
When a nest is identified, research shows that Nomada females consider three essential aspects: 1) the susceptibility and excellence of the host cell, 2) the potential danger from a maternal host's presence, and 3) the level of competition with other Nomada bees.
