Camponotus japonicus
In 3 days ~40% in a week ~70%
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 20% of wildlife watchers report a Japanese Carpenter Ant sighting in Wuhan on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 18th most-seen of the 62 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March–July and September
In those months about 20% of wildlife watchers report a Japanese Carpenter Ant in Wuhan on a given day, against under 5% in August and October–February, the lowest months.
9th of 15
Of the 15 cities where we can rate Japanese Carpenter Ant sightings, Wuhan ranks 9th at about 20%. The best odds are in Busan (South Korea, about 30%), Hefei (China, about 30%) and Harbin (China, about 30%).
Same order: Hymenoptera
The closest relatives of the Japanese Carpenter Ant that you can see in Wuhan (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Yellow-Legged Hornet (about 30%), Asian Honey Bee (about 30%) and Asian Giant Hornet (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Japanese Carpenter Ant is recorded against all the insects logged in Wuhan (11 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.
