Smerinthus planus
In 3 days ~10% in a week ~20%
Smerinthus planus, the Oriental eyed hawkmoth, is a moth of the family Sphingidae. It was described by Francis Walker in 1856. It is found from northern Xinjiang across northern China, Mongolia and south-eastern Siberia to the Russian Far East and Japan, and then south through Korea and Taiwan to Hainan, Yunnan and eastern Tibet.
The wingspan is 70–100 mm. There are probably two generations per year in western China. Depending on latitude and weather, there are between one and four generations further east in China, with adults on wing between April and September.
The larvae feed on Populus and Salix species. Wikipedia →

Rare
Under 5% of wildlife watchers report an Oriental Eyed Hawkmoth sighting in Beijing on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 247th 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 20%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report an Oriental Eyed Hawkmoth in Beijing on a given day, against under 5% in June to April, the lowest months.
Among the best
Of the 2 cities where we can rate Oriental Eyed Hawkmoth sightings, Beijing ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Seoul (South Korea, under 5%).
Same family: Sphingidae
The closest relatives of the Oriental Eyed Hawkmoth 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 Oriental Eyed Hawkmoth is recorded against all the insects logged in Beijing (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.
