In 3 days ~10%
Spirama helicina is a moth of the family Erebidae first described by Jacob Hübner in 1824. In older texts, the species was classified as morph of Spirama retorta. The wingspan is 60–70 mm. As in many species of genus Spirama, the pattern on the wings when the moth is resting looks like the face of a snake with slightly opened mouth. Forewings with arched costa towards apex, which is nearly rectangular. Male with a fold on inner area of hindwings, containing an erectile ridge of very long hair. Antennae fasciculate. Very similar to S. retorta, but differs from more brightly colored than that species. Female with ochreous sub-marginal line of hindwings crenulate. Male has dark chestnut brown head and collar. Thorax paler with dark bands. Abdomen crimson with triangular black dorsal patches. Wings fuscous brown. A large "inverted comma" mark found beyond end of cell, with ochreous and black edges and some white on inner edge of "tail", the center fuscous black.
It is found in Russia (south-eastern Siberia, Ussuri, Primorye), China (Sichuan, Yunnan), Taiwan, Korea, Japan (Honshu, Kyushu), India (Assam, Meghalaya, Orissa, West Bengal), Nepal, Thailand... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spirama helicina sighting in Tokyo on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 929th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Spirama helicina in Tokyo on a given day, so our monthly data shows no clear season.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Spirama helicina sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spirama helicina is recorded against all the insects logged in Tokyo (5 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.
