This is the only genus of army ants found in California. These are nomadic, predacious ants that engage in group foraging. Workers are usually active at night, and often forage below the soil surface. Other ant species (both adults and brood) appear to be the principal prey items of Neivamyrmex , although the habits of the smaller, subterranean species are not well known.
