For ants, the ability to instantly distinguish nestmates from outsiders who might hijack the colony is crucial. Now, a new study shows that the system that ants use to determine who belongs in the colony is far more flexible than once thought. The findings, published in Current Biology, demonstrate how clonal raider ants update their sense of nestmate identity throughout adulthood through repeated exposure, while still retaining an intrinsic recognition of their kin.
