Langia zenzeroides, the apple hawkmoth, is a species of moth in the family Sphingidae. It was described by Frederic Moore in 1872. It is found in northern India, eastern and southern China, South Korea, northern Thailand, northern Vietnam, Japan and Taiwan.
The wingspan is 100–156 mm. In northern China, there is one generation per year, with adults on wing from April to May. In Korea, adults have been recorded from late April to mid-May and in Thailand, the main flight period is January and February. They also are very large compared to a regular moth.
The larvae have been recorded on Prunus persica, but feed on most woody Rosaceae species, such as cherries, apples, pears and medlars. Langia zenzeroides zenzeroides (northern India, eastern and southern China, South Korea, northern Thailand and northern Vietnam) Wikipedia →

Rare
Under 5% of wildlife watchers report an Apple Hawkmoth sighting in Seoul on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 319th most-seen of the 525 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.
April
In that month about 10% of wildlife watchers report an Apple Hawkmoth in Seoul on a given day, against under 5% in May to March, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Apple Hawkmoth sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Seoul, in our data
Seoul is the only city on Wallace's Line with enough records to rate Apple Hawkmoth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Sphingidae
The closest relatives of the Apple Hawkmoth that you can see in Seoul (family Sphingidae, Sphinx Moths) are Theretra japonica (about 10%), Clanis bilineata (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 Apple Hawkmoth is recorded against all the insects logged in Seoul (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.
