Biology

Workers are unable to forage outside the nest and are not capable of brood tending or feeding themselves. Host species workers (slaves) are needed for the continuation of the colony. In mixed colonies no host queen can survive, though unmated gynes of the host species frequently develop from raided pupae. They dealate and serve as slaves. Host brood is commonly not devoured. During raids, host species eggs are even discarded outside the host nest and are not carried to the slavemaker nest.

Harpagoxenus sublaevis is a species with queen polymorphism. Most functional queens are wingless ergatoid queens that usually look like large workers; alate queens are very rare and seem absent in northern parts of the range. A genetical mechanism is claimed to underlie this queen polymorphism.

Collingwood (1979) - In Denmark and Fennoscandia nests containing host species and inquiline are commonly found in twigs on the ground, tree stumps or under bark but in the mountains of Central Europe they occur rarely under stones.
