Amata fortunei, the white-spotted moth, is a moth of the family Erebidae. The species was first described by d'Orza in 1869. It is found in Japan, South Korea and Taiwan. The wingspan is 30–37 mm. It is a day-flying species. There are two generations per year, with adults on wing from early June to mid July and again from mid August to mid September.
The larvae feed on the leaves of Trifolium repens, Taraxacum species, Equisetum arvense and Typha angustifolia. They are known to eat dead leaves as well as living tissue. Wikipedia →

Possible
About 20% of wildlife watchers report a Japanese Nine-Spotted Moth sighting in Nagoya on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 52nd most-seen of the 195 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 60% of wildlife watchers report a Japanese Nine-Spotted Moth in Nagoya on a given day, against under 5% in July and September–May, the lowest months.
Among the best
Of the 7 cities where we can rate Japanese Nine-Spotted Moth sightings, Nagoya ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Sendai (Japan, about 20%).
Same family: Erebidae
The closest relatives of the Japanese Nine-Spotted Moth that you can see in Nagoya (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Oriental Fruit-Piercing Moth (about 20%), Ramie Moth (about 10%) and Oraesia emarginata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Japanese Nine-Spotted Moth is recorded against all the insects logged in Nagoya (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.
