With luck
About 10% of wildlife watchers report a Willow Leaf Beetle sighting in Seoul on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 170th most-seen of the 525 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.
March–July and September
In those months about 10% of wildlife watchers report a Willow Leaf Beetle in Seoul on a given day, against under 5% in August and October–February, the lowest months.
Among the best
Of the 21 cities where we can rate Willow Leaf Beetle sightings, Seoul ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Sendai (Japan, about 10%), Rotterdam [The Hague] (Netherlands, about 10%) and Boston (United States, about 10%).
Same family: Chrysomelidae
The closest relatives of the Willow Leaf Beetle that you can see in Seoul (family Chrysomelidae, Leaf Beetles) are Chrysochus chinensis (about 10%) and Ragweed Leaf Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Willow Leaf Beetle is recorded against all the insects logged in Seoul (19 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.
