Biology. This is the famous Amazon ant. Raiding forays are carried out by small troops of workers on hot days after mid summer and are invariably successful. The adversary ants are decapitated or have their heads pierced by the PolyergusHNS with their pincerlike jaws. The worker pupae of members of the Formica fuscaHNS group, usually F. fuscaHNS or F. rufibarbisHNS, are carried back to the parent nest for rearing as auxiliary workers by ants of the same or similar species introduced by earlier raids. Single queens whether ergatoid or normal secure adoption in nests of the auxiliary species by destroying and replacing the host queen. A mature colony may consist of a few dozen to a few hundred PolyergusHNS workers and many more up to a few thousand of the auxiliary species. Queens and workers are unable to feed themselves or to rear brood. Nests are under flat stones in warm sheltered places.
