Epiblema foenella, the white-foot bell, is a moth of the family Tortricidae. The wingspan is 17–26 mm. This quite-common moth has dark brown forewings with a striking falcate medio-dorsal white marking and a gray-colored area at the ends of the wings. The shape of the white marking is quite variable.
This species has one generation and the mature caterpillars overwinter. The larvae feed on the roots and lower stem of mugwort or common wormwood (Artemisia vulgaris), of southernwood (Artemisia abrotanum) and of golden marguerite (Anthemis tinctoria). The moth flies from May to August depending on the location. They usually fly from late afternoon into the evening.
This species can be found in most of Europe, southern Russia, the Caucasus, Siberia, Kazakhstan, Kyrgyzstan, Mongolia, the Russian Far East, China (Tianjin, Hebei, Inner Mongolia, Jilin, Heilongjiang, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong, Henan, Hubei, Hunan, Guangxi, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu, Qinghai, Ningxia, Xinjiang), Korea, Japan, India, Taiwan and Vietnam.
The white-foot bell prefers rough uncultivated ground, grassland, scrub, river banks... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-Foot Bell sighting in Seoul on a given day, based on 8 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.
July and August
In those months about 10% of wildlife watchers report a White-Foot Bell in Seoul on a given day, against under 5% in September to June, the lowest months. Those are among Seoul's wettest months, with about 310 mm of rain a month against 20 mm in January.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most White-Foot Bell 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.
7th of 11
Of the 11 cities where we can rate White-Foot Bell sightings, Seoul ranks 7th at under 5%. The best odds are in Helsinki (Finland, about 10%), Novosibirsk (Russia, about 10%) and Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the White-Foot Bell is recorded against all the insects logged in Seoul (8 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.
