Rare
Under 5% of wildlife watchers report a Powdered Oakblue sighting in Osaka on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 271st most-seen of the 352 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.
January and August–November
In those months about 10% of wildlife watchers report a Powdered Oakblue in Osaka on a given day, against under 5% in February–July and December, the lowest months.
5th of 5
Of the 5 cities where we can rate Powdered Oakblue sightings, Osaka ranks 5th at under 5%. The best odds are in Nanjing (China, about 10%), Tokyo (Japan, about 10%) and Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Powdered Oakblue is recorded against all the insects logged in Osaka (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.
