With luck
About 10% of wildlife watchers report a Yellow-Vented Hornet sighting in Nanjing on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 188th most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Yellow-Vented Hornet in Nanjing on a given day, against under 5% in February–March, May–July, September and November–December, the lowest months. That is one of Nanjing's driest months, with about 50 mm of rain against 240 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yellow-Vented Hornet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
9th of 11
Of the 11 cities where we can rate Yellow-Vented Hornet sightings, Nanjing ranks 9th at about 10%. The best odds are in Nagoya (Japan, about 20%), Yogyakarta (Indonesia, about 10%) and Sendai (Japan, about 10%).
Same genus: Vespa
The closest relatives of the Yellow-Vented Hornet that you can see in Nanjing (genus Vespa, Hornets) are Yellow-Legged Hornet (about 20%), Black-Bellied Hornet (about 20%) and European Hornet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-Vented Hornet is recorded against all the insects logged in Nanjing (8 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.
