Summary First descendants' founding ability was tested inP. dominulus colonies by experimentally removing the original nests and queens 21–24 days after the first emergence. Foundation tests were carried out after three different periods had elapsed after the removal and the results were analyzed with regards to the effects of participation in social tasks, duration of stay within the colony and seasonal factors. 1.Immediately after the removal, the foundations that occurred were performed almost entirely by workers, regardless of the duration of their stay within the colony. The number of foundations depended on the season in which the females had emerged. 2.Two months and four months after the removal, foundations were made by only a small number of females (workers and non-workers). These females, which were therefore able to found a nest the year they were born, were mostly among the very first-born individuals in the colonies. 3.The following year after hibernation: females (workers and non-workers) which had stayed for only a short time within the colony (1–15 days) had the highest survival rates. The foundation rates among the surviving females depended only on seasonal factors, since the foundation rates were higher among the non-workers which had emerged later in the season. The results throw some light on the first descendants' nest-founding potential in colonies developing under natural conditions, where many workers in fact stay for only a short time at the nest.
