Rare
Under 5% of wildlife watchers report a Four-Spotted Footman sighting in Tokyo on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 509th 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 Four-Spotted Footman in Tokyo on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Four-Spotted Footman sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
12th of 14
Of the 14 cities where we can rate Four-Spotted Footman sightings, Tokyo ranks 12th at under 5%. The best odds are in Kharkiv (Ukraine, about 30%), Porto (Portugal, about 10%) and Vienna (Austria, about 10%).
Same family: Erebidae
The closest relatives of the Four-Spotted Footman that you can see in Tokyo (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Japanese Nine-Spotted Moth (about 10%), Ramie Moth (about 10%) and Brown-Striped Semilooper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Four-Spotted Footman is recorded against all the insects logged in Tokyo (16 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.
