Hyenism in Ants: Non-Target Ants Profit From Polyergus rufescens Raids (Hymenoptera: Formicidae)

The presence of slavemaker ants alters the structure of the ant community. The influence of slavemakers on non-host ants is believed to be indirect, via changing competitive interactions among the ants. According to my observation Myrmica sabuleti (and probably also Lasius alienus) profited from a Polyergus rufescens raid against a Formica fusca nest. Both non-host species collected F. fusca corpses. These carcasses were used as food in the case of M. sabuleti at least. M. sabuleti profited substantially from the Polyergus raid because the dry biomass weight of the collected F. fusca carcasses was approximately half of the dry biomass weight of all M. sabuleti workers
