Rare
Under 5% of wildlife watchers report a Black Longicorn Beetle sighting in Seoul on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 291st 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 30%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Black Longicorn Beetle 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.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black Longicorn Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 10 cities where we can rate Black Longicorn Beetle sightings, Seoul ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Stockholm (Sweden, under 5%), Prague (Czechia, under 5%) and Berlin (Germany, under 5%).
Same family: Cerambycidae
The closest relatives of the Black Longicorn Beetle that you can see in Seoul (family Cerambycidae, Longhorn Beetles) are Thin-Winged Longicorn Beetle (about 10%), Oak Longicorn Beetle (about 10%) and Citrus Longhorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Longicorn Beetle is recorded against all the insects logged in Seoul (9 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.
