Polyergus rufescens
''Polyergus rufescens'' is a species of slave-making ant native to southern Europe and parts of Asia, commonly referred to as the European Amazon ant or as the slave-making ant.

A newly mated female ''Polyergus rufescens'' needs to make its way into one of these "host" nests, kill the host queen and be accepted by the host workers in her place.
