In 3 days ~10% in a week ~30%
Ampelophaga rubiginosa is a moth of the family Sphingidae. It was described by Otto Vasilievich Bremer and William (Vasilii) Grey in 1853. It is found from north-eastern Afghanistan, east around the southern margin of the Himalaya to Yunnan, then throughout China to the Russian Far East, the Korean Peninsula and Japan. It is also found south through Thailand and Vietnam to Sumatra and Peninsular Malaysia.
The wingspan is 72–100 mm. There is one generation per year in north-eastern China, with adults on wing from June to August. Further south, there may be up to three generations per year. In Shanghai, adults are on wing from February to October. In Korea, they are found from early May to early August.
Larvae have been recorded feeding on Vitaceae species (including Cayratia, Parthenocissus and Vitis), Hydrangea paniculata and Saurauia. Ampelophaga rubiginosa rubiginosa Ampelophaga rubiginosa lohita Kishida & Yano, 2001 (Japan (Kyushu and the Ryukyu Archipelago))

Rare
Under 5% of wildlife watchers report an Ampelophaga rubiginosa sighting in Beijing on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 201st 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.
June–August and December
In those months about 10% of wildlife watchers report an Ampelophaga rubiginosa in Beijing on a given day, against under 5% in January–May and September–November, the lowest months. Those are among Beijing's wettest months, with about 85 mm of rain a month against almost none in January.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Ampelophaga rubiginosa sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
3rd of 4
Of the 4 cities where we can rate Ampelophaga rubiginosa sightings, Beijing ranks 3rd at under 5%. The best odds are in Nanjing (China, about 10%) and Seoul (South Korea, under 5%).
Same family: Sphingidae
The closest relatives of the Ampelophaga rubiginosa 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 Ampelophaga rubiginosa is recorded against all the insects logged in Beijing (11 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.
