Michener and Kerfoot (1967) studied the habits of Caenaugochlora costaricensis, and reported the species to be semisocial. Nests are constructed in earthen banks; about two-thirds of the nests are built and guarded bylone females. In some cases nests are later reused and enlarged by a group of bees (apparently sisters) that work together.
