Rare
Under 5% of wildlife watchers report a Donacia bicoloricornis sighting in Seoul on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 460th 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
In that month about 10% of wildlife watchers report a Donacia bicoloricornis in Seoul on a given day, against under 5% in August to June, the lowest months. That is one of Seoul's wettest months, with about 360 mm of rain against 20 mm in January.
Only Seoul, in our data
Seoul is the only city on Wallace's Line with enough records to rate Donacia bicoloricornis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Chrysomelidae
The closest relatives of the Donacia bicoloricornis that you can see in Seoul (family Chrysomelidae, Leaf Beetles) are Chrysochus chinensis (about 10%), Ragweed Leaf Beetle (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 Donacia bicoloricornis is recorded against all the insects logged in Seoul (5 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.
