Camponotus japonicus
In 3 days ~60% in a week ~90%
Camponotus japonicus, commonly known as the Japanese carpenter ant, is a species of ant native to eastern 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.
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 have three ocelli.
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. The ant has sensilla, which can recognize CHC-mixtures from non-nestmates, to which it can be aggressive.
Camponotus japonicus inhabits a wide range, including Japan, Korea, Pakistan, Iran, the Philippines, China, Mongolia and Russia... Wikipedia →

No species of the same family or order lives in Harbin, so these are its closest relatives here: other insects.
Possible
About 30% of wildlife watchers report a Japanese Carpenter Ant sighting in Harbin on a given day, based on 7 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June and August
In those months about 50% of wildlife watchers report a Japanese Carpenter Ant in Harbin on a given day, against under 5% in April–May and September–October, the lowest months. Those are among Harbin's wettest months, with about 110 mm of rain a month against 5 mm in January.
Among the best
Of the 15 cities where we can rate Japanese Carpenter Ant sightings, Harbin ranks 3rd at about 30%, level with the leaders once rounded. The best odds are in Busan (South Korea, about 30%) and Hefei (China, about 30%).
GBIF citizen-science records
It is estimated from how often the Japanese Carpenter Ant is recorded against all the insects logged in Harbin (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
