formica sanguinea

Like other Servifusca, this species is subject to raids by dulotic species such as Formica sanguinea and Polyergus rufescens where their ranges coalesce.

P. formicarum is found in Europe, and is parasitic on the ants Lasius alienus, Lasius niger, Lasius emarginatus, Lasius flavus, Lasius fuliginosus, Formica sanguinea, Myrmica lobicornis and others.
