Formica subintegra is a species of slave-making ant in the genus Formica.[1]Formica subintegra seems to be obligate parasites, enslaving ants of the fusca group of Formica. The ants are not active outside the nest except during slave-raids; foraging is conducted entirely by their slaves, which make up 70-90% of the colony.[2]
