Hypomecis punctinalis, the pale oak beauty, is a moth of the family Geometridae. The species was first described by Giovanni Antonio Scopoli in his 1763 Entomologia Carniolica. The species can be found in central and southern Europe, Asia Minor, Transcaucasia, Russia, the Russian Far East, Japan, Korea, Ussuri and western China.
The wingspan is 46–55 mm. The length of the forewings is 22–26 mm. The forewings have a grey-white ground colour with a brownish tinge and are fine blackish dusted. The outer margin of the forewing has a convexity. The forewings have conspicuous transverse lines and a clear discal mark. The discal mark is pale centred and dark ringed. The forewings of the male have a fovea. The hindwings are similarly marked. The hindwing median and second lines are conspicuously dark and wavy.
The moths fly in one generation from the end of April to July.[1] The larvae feed on various trees including oak and birch. Similar species: Hypomecis roboraria (H.roboraria has a pale spot on a dark background at the apex forewing underside which is not present in H. punctinalis

Rare
Under 5% of wildlife watchers report a Pale Oak Beauty sighting in Seoul on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 353rd 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.
May and July–August
In those months about 10% of wildlife watchers report a Pale Oak Beauty in Seoul on a given day, against under 5% in June and September–April, the lowest months. Those are among Seoul's wettest months, with about 240 mm of rain a month against 20 mm in January.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Pale Oak Beauty sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
9th of 17
Of the 17 cities where we can rate Pale Oak Beauty sightings, Seoul ranks 9th at under 5%. The best odds are in Porto (Portugal, about 20%), Kharkiv (Ukraine, about 10%) and Kyiv (Ukraine, about 10%).
Same family: Geometridae
The closest relatives of the Pale Oak Beauty that you can see in Seoul (family Geometridae, Geometer Moths) are Erannis golda (about 10%) and Biston panterinaria (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pale Oak Beauty is recorded against all the insects logged in Seoul (7 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.
