With luck
About 10% of wildlife watchers report a Four-Tipped Darter sighting in Beijing on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 401 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.
June to September
In those months about 10% of wildlife watchers report a Four-Tipped Darter in Beijing on a given day, against under 5% in October to May, the lowest months. Those are among Beijing's wettest months, with about 100 mm of rain a month against almost none in January.
7th of 7
Of the 7 cities where we can rate Four-Tipped Darter sightings, Beijing ranks 7th at about 10%. The best odds are in Daegu (South Korea, about 30%), Nagoya (Japan, about 10%) and Osaka (Japan, about 10%).
Same genus: Sympetrum
The closest relatives of the Four-Tipped Darter that you can see in Beijing (genus Sympetrum, Meadowhawks) are Nomad (about 10%) and Spotted Darter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Four-Tipped Darter is recorded against all the insects logged in Beijing (34 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.
