Abstract

Colony composition inCardiocondyla wroughtoni and the fighting and mating behaviors of 2 types of males, alates and ergatoids, are described. This species is polygynous, with a mean of 7.0 queens per nest, and forms polycalic colonies. Within nests, ergatoid males fight with each other, leading to the death of all but one in single nests. On the other hand, alate males exhibit no aggressive behavior towards any of their colony members. Both types of males conduct intranidal mating with their sisters, though the alate males also conduct nuptial flights. Many alate females leave their maternal nest even if they have already been inseminated by intranidal mating.
