Rare
Under 5% of wildlife watchers report a Black-Tailed Hornet sighting in Guangzhou on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 294th most-seen of the 482 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.
July and September
In those months about 10% of wildlife watchers report a Black-Tailed Hornet in Guangzhou on a given day, against under 5% in August and October–June, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-Tailed Hornet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
10th of 11
Of the 11 cities where we can rate Black-Tailed Hornet sightings, Guangzhou ranks 10th at under 5%. The best odds are in Hefei (China, about 20%), Taichung (Taiwan, about 10%) and Taipei (Taiwan, about 10%).
Same genus: Vespa
The closest relatives of the Black-Tailed Hornet that you can see in Guangzhou (genus Vespa, Hornets) are Yellow-Legged Hornet (about 10%), Black Shield Hornet (about 10%) and Lesser Banded Hornet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-Tailed Hornet is recorded against all the insects logged in Guangzhou (9 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.
