In 3 days ~10% in a week ~20%
Vespula flaviceps is a species of social wasp in the genus Vespula. It found in Eastern Asia and Japan. Studies have suggested that the queens of this species may mate with more males and use sperm more evenly. The reason for this is not yet well understood.
V. flaviceps is native to Eastern Asia and Japan. It can be found most prominently on the Japanese Islands, but is also present in South Korea and the southern portion of Primorsky Krai. Its population may be threatened by invasive raccoons, which prey upon it during the summer and autumn.
V. flaviceps is found in forests. During a two-year study in Japan, the species was observed to be one of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Asian Yellowjacket sighting in Hong Kong on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 648th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February and March
In those months about 10% of wildlife watchers report a Common Asian Yellowjacket in Hong Kong on a given day, against under 5% in April to January, the lowest months. Those are among Hong Kong's driest months, with about 50 mm of rain a month against 280 mm in June.
9th of 9
Of the 9 cities where we can rate Common Asian Yellowjacket sightings, Hong Kong ranks 9th at under 5%. The best odds are in Guiyang (China, about 30%), Hefei (China, about 20%) and Kunming (China, about 10%).
Same family: Vespidae
The closest relatives of the Common Asian Yellowjacket that you can see in Hong Kong (family Vespidae, Hornets, Paper Wasps, Potter Wasps, and Allies) are Yellow-Legged Hornet (about 20%), Black Shield Hornet (about 10%) and Parapolybia indica (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Asian Yellowjacket is recorded against all the insects logged in Hong Kong (12 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.
