In 3 days ~10% in a week ~30%
Callambulyx tatarinovii, or unmonsuzume (ウンモンスズメ) in Japanese, is a moth of the family Sphingidae. The species was first described by Otto Vasilievich Bremer and William (Wasilii) Grey in 1853. It is found from northern Xinjiang across northern China, Mongolia, southern Siberia to the Russian Far East and Japan, and then south through Korea and central China to eastern Tibet. It is also found in Taiwan.
The wingspan is 56–82 millimetres (2.2–3.2 in). It is very similar to Smerinthus kindermannii. There are one to two generations per year in China. In Korea, adults are on wing from early May to mid-October.

With luck
About 10% of wildlife watchers report a Callambulyx tatarinovii sighting in Beijing on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Callambulyx tatarinovii in Beijing on a given day, against under 5% in September to April, the lowest months. Those are among Beijing's wettest months, with about 95 mm of rain a month against almost none in January.
Among the best
Of the 3 cities where we can rate Callambulyx tatarinovii sightings, Beijing ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Nanjing (China, about 10%) and Seoul (South Korea, about 10%).
Same family: Sphingidae
The closest relatives of the Callambulyx tatarinovii that you can see in Beijing (family Sphingidae, Sphinx Moths) are Eurasian Hummingbird Hawkmoth (about 10%), Plain Grey Hawkmoth (about 10%) and Convolvulus Hawkmoth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Callambulyx tatarinovii is recorded against all the insects logged in Beijing (19 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.
