Rare
Under 5% of wildlife watchers report a Polionemobius taprobanense sighting in Tokyo on a given day, based on 46 verified sightings from GBIF citizen-science data. It is the 302nd 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.
September and October
In those months about 10% of wildlife watchers report a Polionemobius taprobanense in Tokyo on a given day, against under 5% in November to August, the lowest months. Those are among Tokyo's wettest months, with about 230 mm of rain a month against 75 mm in February.
10th of 11
Of the 11 cities where we can rate Polionemobius taprobanense sightings, Tokyo ranks 10th at under 5%. The best odds are in Beijing (China, about 10%), Osaka (Japan, about 10%) and Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 10%).
GBIF citizen-science records
It is estimated from how often the Polionemobius taprobanense is recorded against all the insects logged in Tokyo (46 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.
