Rare
Under 5% of wildlife watchers report a Blue-Spotted Emperor sighting in Tokyo on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 290th 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.
April to June
In those months about 10% of wildlife watchers report a Blue-Spotted Emperor in Tokyo on a given day, against under 5% in July to March, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Blue-Spotted Emperor sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Blue-Spotted Emperor sightings, Tokyo ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Seoul (South Korea, under 5%).
GBIF citizen-science records
It is estimated from how often the Blue-Spotted Emperor is recorded against all the insects logged in Tokyo (40 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.
