Rare
Under 5% of wildlife watchers report a Bastilla arctotaenia sighting in Tokyo on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 482nd 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 Bastilla arctotaenia in Tokyo on a given day, so our monthly data shows no clear season.
2nd of 3
Of the 3 cities where we can rate Bastilla arctotaenia sightings, Tokyo ranks 2nd at under 5%. The best odds are in Osaka (Japan, about 10%).
Same family: Erebidae
The closest relatives of the Bastilla arctotaenia 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 Bastilla arctotaenia is recorded against all the insects logged in Tokyo (17 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.
