The reproductive behavior of Eurysternus plebejus Harold under laboratory conditions is described. Following a feeding period, reproduction takes place starting with a nuptial feast characterized by female production of food balls. Mating then takes place prior to nesting. One or two compound nests are made during the lifespan of the female. Nests are located in a crater beneath a dung pat, and contain several brood balls that are cared for by the female until emergence of the offspring. Larvicide does not occur. Males live for a significantly shorter time than females.
