Rare
Under 5% of wildlife watchers report a Sympetrum risi sighting in Tokyo on a given day, based on 69 verified sightings from GBIF citizen-science data. It is the 215th most-seen of the 1013 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.
July to October
In those months about 10% of wildlife watchers report a Sympetrum risi in Tokyo on a given day, against under 5% in November to June, the lowest months.
4th of 4
Of the 4 cities where we can rate Sympetrum risi sightings, Tokyo ranks 4th at under 5%. The best odds are in Daegu (South Korea, about 20%), Nagoya (Japan, about 10%) and Osaka (Japan, about 10%).
Same genus: Sympetrum
The closest relatives of the Sympetrum risi that you can see in Tokyo (genus Sympetrum, Meadowhawks) are Autumn Darter (about 10%), Four-Tipped Darter (about 10%) and Banded Darter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sympetrum risi is recorded against all the insects logged in Tokyo (69 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.
