Camponotus japonicus, more often known under the common name Japanese carpenter ant, is a species of ant native to East Asia. It is black, and one of the largest ants. A nest has about ten to thousands of individuals, and it can be a pest when it enters households or protects aphids. There are several subspecies of this ant in different areas of Asia, with the largest of the species being located in Northern China.[citation needed]


The queen is black, but has microscopic brown hair protruding from the thorax and abdomen. They are 17 millimeters long. Before mating, the queen has four transparent brown wings supported by brown veins. The 12-millimeter-long male has a longer and straighter antennae and a slimmer body. Unlike the workers, both the queen and the male has three ocelli.[citation needed]

The workers are divided into three subcastes based on their size, which varies from 6 to 15 millimeters. The largest subcaste of workers is also called the soldier.[citation needed]


Camponotus japonicus inhabit a wide range, including Japan, Korea, Myanmar, the Philippines, China, Mongolia and Siberia.[citation needed]
