With luck
About 10% of wildlife watchers report a Japanese Cockchafer sighting in Tokyo on a given day, based on 93 verified sightings from GBIF citizen-science data. It is the 151st most-seen of the 1013 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.
July
In that month about 20% of wildlife watchers report a Japanese Cockchafer in Tokyo on a given day, against under 5% in September to June, the lowest months.
Among the best
Of the 3 cities where we can rate Japanese Cockchafer sightings, Tokyo ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Fukuoka (Japan, about 10%) and Sendai (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Japanese Cockchafer is recorded against all the insects logged in Tokyo (93 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.
