With luck
About 10% of wildlife watchers report a Dolichus halensis sighting in Seoul on a given day, based on 21 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.
August and September
In those months about 10% of wildlife watchers report a Dolichus halensis in Seoul on a given day, against under 5% in October to July, the lowest months. Those are among Seoul's wettest months, with about 200 mm of rain a month against 20 mm in January.
Among the best
Of the 7 cities where we can rate Dolichus halensis sightings, Seoul ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%).
Same family: Carabidae
The closest relatives of the Dolichus halensis that you can see in Seoul (family Carabidae, Ground Beetles) are Carabus jankowskii (about 10%), East Asian Tiger Beetle (about 10%) and Cylindera elisae (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dolichus halensis is recorded against all the insects logged in Seoul (21 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.
