我们回顾了行军蚁的有性繁殖和群体分裂的不寻常过程，并简要地将其与其他蚂蚁的繁殖进行了比较。行军蚁是一个多系群，其特征是趋同进化的综合征，包括群体规模大、集体觅食大型猎物、游牧、周期性产卵以及体型大且无翅的蚁后。由于蚁后不会飞，也不会离开蚁群，工蚁可以选择哪位蚁后接管每个新蚁群。雄性在蚁群之间飞行，必须经过外来蚁群中工蚁的挑战才能接近蚁后。出于这个原因，工蜂还可以选择哪些雄性将为它们的蜂王授精。因此，行军蚁工蚁可能参与选择新蚁群的女族长和族长。我们认为，这种不寻常的性选择形式导致了所有不同的行军蚁谱系中同种雄性和雌性的相似性。雄性像女王一样，体型大而健壮，有长圆柱形腹部，外分泌腺的形状和位置与雌性相似，当它们进入新的群体时，它们的翅膀会脱落。此外，当雄性进入新的群体时，它们后面会跟着一群工蚁，就像陪伴蚁后的工蚁一样。我们认为，雄性与蚁后相似并不是一种欺骗性的模仿，而是因为在性选择的影响下，它们开始使用与蚁后相同的沟通渠道来展示自己对劳动力的潜在适应性。
We review the unusual processes of sexual reproduction and colony fission in army ants and briefly compare this to reproduction in other ants. Army ants are a polyphyletic group and are characterized by a syndrome of convergently evolved trait including large colony size, group foraging for large prey, nomadism, cyclical brood production and queens who are large and wingless. Because queens are flightless and never leave their colony, workers are in a position to choose which queen will take over each new colony. Males fly between colonies and must run the gauntlet of the workers in alien ones before they can approach the queen. For this reason workers can also choose which males will inseminate their queen. Army ant workers may therefore be involved in choosing both the matriarch and patriarch of new colonies. We suggest that this unusual form of sexual selection has led to the close resemblance of conspecific male and females in all the separate lineages of army ants. Males are queen-like in that they are large and robust, have long cylindrical abdomens, with exocrine glands of similar form and location to those of females and shed their wings when they enter new colonies. Furthermore, when males enter new colonies they are followed by an entourage of workers which resemble those that accompany queens. We suggest that males resemble queens not as a form of deceitful mimicry but because under the influence of sexual selection they have come to use the same channels of communication to demonstrate their potential fitness to the workforce as those used by queens.
