Rare
Under 5% of wildlife watchers report a Eustenogaster nigra sighting in Hong Kong on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 613th 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.
June and September
In those months about 10% of wildlife watchers report a Eustenogaster nigra in Hong Kong on a given day, against under 5% in July–August and October–May, the lowest months. Those are among Hong Kong's wettest months, with about 220 mm of rain a month against 25 mm in December.
2nd of 3
Of the 3 cities where we can rate Eustenogaster nigra sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Tuen Mun (China, about 10%).
Same family: Vespidae
The closest relatives of the Eustenogaster nigra 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 Eustenogaster nigra is recorded against all the insects logged in Hong Kong (13 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.
