在婚礼飞行后，黑蚁蚁后在地面上的密度非常高。在这项研究中，蚁后避开了已建立的殖民地的工蚁经常光顾的区域，导致了巢基的额外聚集。在野外，18%的蚁群基巢含有一只以上的蜂王（多雌）。皇后既没有表现出偏好，也没有避免多形性的创始，这表明foundress协会是兼性的，拥挤和激烈的殖民地间竞争的促进。事实上，在实验室条件下发生了育雏袭击。在这种情况下，蚁后群体具有优势，因为它们最初生产更多的工蚁，而拥有最多工蚁的殖民地在育雏突袭中更成功。蚁后们会战斗到只剩下一只活的。移除工蚁会延迟战斗，而添加工蚁则会导致过早的战斗，这表明工蚁的存在会导致蚁后之间的战斗。一旦工蚁开始觅食，额外的蚁后会对蚁群的生产力产生负面影响：有三个或四个蚁后的蚁群比有一个蚁后的蚁群生产的工蚁少。工蜂也会影响蚁后与蚁后之间的互动结果，因为它们会优先喂养最有生育能力的蚁后，因此最有可能存活下来。无论是体重的女王的时候，婚礼飞行或注射保幼激素影响的结果之间的战斗女王。(C)1995年动物行为研究协会
After the nuptial flight, queens of Lasius niger occur in very high densities on the ground. Queens in this study avoided areas frequented by workers of established colonies, leading to additional clumping of nest foundations. In the field 18% of colony foundation-nests contained more than one queen (pleometrosis). Queens showed neither preference for nor avoidance of pleometrotic founding, indicating that foundress associations are facultative, promoted by crowding and intense inter-colony competition. Indeed, under laboratory conditions brood raiding occurred. In this situation groups of queens had an advantage because they produced more workers initially and the colony with the most workers was more successful in brood raids. The queens in a colony fight until only one is left alive. Removal of workers delayed fighting and addition of workers led to premature fights, indicating that the presence of workers induces fighting amongst the queens. As soon as workers started to forage, additional queens negatively affected colony productivity: colonies with three or four queens produced fewer workers than colonies with one queen. Workers also influenced the outcome of queen-queen interactions, by preferentially feeding the most fertile queen, which was therefore the most likely to survive. Neither weight of the queens by the time of the nuptial flight nor injections of juvenile hormone affected the outcome of fights between queens.
