Rare
Under 5% of wildlife watchers report a The Sorcerer sighting in Tokyo on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 644th 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 The Sorcerer in Tokyo on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most The Sorcerer sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
4th of 5
Of the 5 cities where we can rate The Sorcerer sightings, Tokyo ranks 4th at under 5%. The best odds are in Porto (Portugal, about 10%), Turin (Italy, about 10%) and Lyon (France, under 5%).
GBIF citizen-science records
It is estimated from how often the The Sorcerer is recorded against all the insects logged in Tokyo (12 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.
