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))

With luck
About 10% of wildlife watchers report an Ampelophaga rubiginosa sighting in Nanjing on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 223rd most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June–August and October
In those months about 10% of wildlife watchers report an Ampelophaga rubiginosa in Nanjing on a given day, against under 5% in September and November–May, the lowest months. Those are among Nanjing's wettest months, with about 160 mm of rain a month against 40 mm in December.
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.
Yes
Of the 4 cities where we can rate Ampelophaga rubiginosa sightings, Nanjing has the highest daily chance: about 10%. Next come Seoul (South Korea, under 5%) and Beijing (China, under 5%).
Same family: Sphingidae
The closest relatives of the Ampelophaga rubiginosa that you can see in Nanjing (family Sphingidae, Sphinx Moths) are Theretra japonica (about 10%), Callambulyx tatarinovii (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 Nanjing (6 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.
