Camponotus japonicus
In 3 days ~70% 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 →

Possible
About 30% of wildlife watchers report a Japanese Carpenter Ant sighting in Busan on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 31 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 50% of wildlife watchers report a Japanese Carpenter Ant in Busan on a given day, against under 5% in January and March, the lowest months.
Yes
Of the 15 cities where we can rate Japanese Carpenter Ant sightings, Busan has the highest daily chance: about 30%. Next come Hefei (China, about 30%) and Harbin (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 Busan (18 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.
