 N. ensifer is active throughout the day , where they forage on the ground and sometimes on low herbs . Colonies are found under stones and other objects in tropical dry forests and pine @-@ oak forests . These ants are solitary foragers and predominately feed on insects such as wasps and months . The only known predator of N. ensifer is the giant horned lizard ( Phrynosoma asio ) . While nothing is known about its reproduction , nuptial flight may take place during spring or summer , where queens establish their nests under stones and other objects .
