Rare
Under 5% of wildlife watchers report a Nerthus taivanicus sighting in Beijing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 349th most-seen of the 401 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.
August and September
In those months about 10% of wildlife watchers report a Nerthus taivanicus in Beijing on a given day, against under 5% in October to July, the lowest months. Those are among Beijing's wettest months, with about 85 mm of rain a month against almost none in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Nerthus taivanicus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 cities where we can rate Nerthus taivanicus sightings, Beijing ranks 2nd at under 5%. The best odds are in Nanjing (China, about 10%).
Same order: Hemiptera
The closest relatives of the Nerthus taivanicus that you can see in Beijing (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Spotted Lanternfly (about 30%), Panaorus csikii (about 20%) and Brown Marmorated Stink Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nerthus taivanicus is recorded against all the insects logged in Beijing (5 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.
