With luck
About 10% of wildlife watchers report a Spotted Darter sighting in Beijing on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 143rd 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 30%, if each day is a fresh chance.
August to October
In those months about 10% of wildlife watchers report a Spotted Darter in Beijing on a given day, against under 5% in November to July, the lowest months. Those are among Beijing's wettest months, with about 70 mm of rain a month against almost none in January.
3rd of 4
Of the 4 cities where we can rate Spotted Darter sightings, Beijing ranks 3rd at about 10%. The best odds are in Daegu (South Korea, about 20%) and Seoul (South Korea, about 10%).
Same genus: Sympetrum
The closest relatives of the Spotted Darter that you can see in Beijing (genus Sympetrum, Meadowhawks) are Four-Tipped Darter (about 10%) and Nomad (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spotted Darter is recorded against all the insects logged in Beijing (40 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.
