The prey is usually thought to gain no benefit from being killed by the predator. In social insects, however, the death of a colony member can increase its inclusive fitness if it contributes to the survival of its colony. We investigated the effects the specialist predator ant Pachycondyla chinensis, and the generalist predator ant Lasius productus on the survival of termite colonies. Here we show that coexisting with P. chinensis increase survival of the termite colony in the presence of another predator. We found that P. chinensis has a sustainable foraging strategy avoiding the annihilation of the termite colony, while L. productus quickly terminated the prey colony. In addition, P. chinensis eliminated L. productus when both of the ant species were placed in the same container. These results suggest that termite colonies nesting in the same wood with the specialist predator P. chinensis would have higher survivorship under the presence of another predator. In conclusion, even though a portion of members were preyed on, living with P. chinensis is advantageous to the survival of the termite colony and thus preyed individuals. This is the first demonstration of “the benefit of being preyed on” in the true predator-prey relationship.
