Rare
Under 5% of wildlife watchers report a Blue Shield Bug sighting in Seoul on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 353rd 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 Blue Shield Bug 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 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Blue Shield Bug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 11
Of the 11 cities where we can rate Blue Shield Bug sightings, Seoul ranks 7th at under 5%. The best odds are in Birmingham (United Kingdom, about 10%), Manchester (United Kingdom, under 5%) and Liverpool (United Kingdom, under 5%).
Same family: Pentatomidae
The closest relatives of the Blue Shield Bug that you can see in Seoul (family Pentatomidae, Stink Bugs) are Brown Marmorated Stink Bug (about 10%), Oriental Stink Bug (about 10%) and Painted Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue Shield Bug is recorded against all the insects logged in Seoul (7 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.
