Rare
Under 5% of wildlife watchers report a Cassida versicolor sighting in Tokyo on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 534th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cassida versicolor in Tokyo on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Cassida versicolor sightings, Tokyo ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Hong Kong (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Cassida versicolor is recorded against all the insects logged in Tokyo (15 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.
