Possible
About 20% of wildlife watchers report a Greater Blue Skimmer sighting in Busan on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 31 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Greater Blue Skimmer in Busan on a given day, against under 5% in September to May, the lowest months. That is one of Busan's wettest months, with about 290 mm of rain against 40 mm in January.
4th of 11
Of the 11 cities where we can rate Greater Blue Skimmer sightings, Busan ranks 4th at about 20%. The best odds are in Naha (Japan, about 30%), Nagoya (Japan, about 20%) and Osaka (Japan, about 20%).
GBIF citizen-science records
It is estimated from how often the Greater Blue Skimmer is recorded against all the insects logged in Busan (8 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.
