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 Tokyo on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 612th most-seen of the 1013 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Ampelophaga rubiginosa in Tokyo on a given day, so our monthly data shows no clear season.
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.
4th of 4
Of the 4 cities where we can rate Ampelophaga rubiginosa sightings, Tokyo ranks 4th at under 5%. The best odds are in Nanjing (China, about 10%), 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 Tokyo (family Sphingidae, Sphinx Moths) are White-Banded Hunter Hawkmoth (about 20%), Maile Pilau Hornworm (about 10%) and Pellucid 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 Tokyo (13 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.
