Formica cinerea
From Collingwood (1979) [1]
This species characteristically occurs in drift sand on coastal dunes in North Europe but also locally inland on coarse morainic drift. It is an aggressive species living largely by predation. Nests may be founded by single queens but where the species is pop¬ulous, colonies are frequently polygynous and polycalic. Alatae occur in July. Its ecology and distribution in Finland are described by Kilpainen, Valkeila, Vesajoki and Wuorenrinna(1977).
