Rare
Under 5% of wildlife watchers report a Svistella bifasciata sighting in Tokyo on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 416th 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 20%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report a Svistella bifasciata 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.
6th of 6
Of the 6 cities where we can rate Svistella bifasciata sightings, Tokyo ranks 6th at under 5%. The best odds are in Nagoya (Japan, about 10%), Hangzhou (China, about 10%) and Nanjing (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Svistella bifasciata is recorded against all the insects logged in Tokyo (24 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.
