An insect of the family Formicidae in the order Hymenoptera. It is the most common species of ant in the subfamily Porphyrinae, with worker ants measuring 4.5-5 mm in length and black with a slight sheen. It nests underground or in rotten wood, and is carnivorous, preying on small insects. Male and female winged ants appear in early summer. It is found throughout Japan except for Hokkaido and the northern part of the Tohoku region, and is also known to be found in the Korean peninsula, Taiwan, and parts of China. Its venomous stinger is well developed, and when it stings, it causes a pain similar to that of a bee sting. Generally, it has little connection to human life, but there have been cases where this ant has appeared in mine tunnels and caused harm to workers.
