With luck
About 10% of wildlife watchers report a Ragweed Leaf Beetle sighting in Seoul on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 143rd 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 40%, if each day is a fresh chance.
May–July and September
In those months about 10% of wildlife watchers report a Ragweed Leaf Beetle in Seoul on a given day, against under 5% in August and October–April, the lowest months. Those are among Seoul's wettest months, with about 170 mm of rain a month against 20 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ragweed Leaf Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 13 cities where we can rate Ragweed Leaf Beetle sightings, Seoul ranks 6th at about 10%, level with the leaders once rounded. The best odds are in Turin (Italy, about 10%), Bucharest (Romania, about 10%) and Lyon (France, about 10%).
Same family: Chrysomelidae
The closest relatives of the Ragweed Leaf Beetle that you can see in Seoul (family Chrysomelidae, Leaf Beetles) are Chrysochus chinensis (about 10%) and Willow Leaf Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ragweed Leaf Beetle is recorded against all the insects logged in Seoul (23 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.
