Diacamma ant. Diacamma ants show no physical differences between the worker and reproductive castes, and each individual has the potential to reproduce up to early adulthood. Bottom: Representing the more typical condition, Wasmannia auropunctata queens are surrounded by much smaller worker ants.  Differences between queens and workers are fixed in early larval development.
