Rare
Under 5% of wildlife watchers report a Curved-Ribbon sighting in Tokyo on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 726th 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 Curved-Ribbon 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 Curved-Ribbon sightings, Tokyo ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Baltimore (United States, under 5%).
Same family: Erebidae
The closest relatives of the Curved-Ribbon 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 Curved-Ribbon is recorded against all the insects logged in Tokyo (9 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.
