Rare
Under 5% of wildlife watchers report a Pale-Spotted Emperor sighting in Bangkok on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 173rd most-seen of the 245 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.
April and September
In those months about 10% of wildlife watchers report a Pale-Spotted Emperor in Bangkok on a given day, against under 5% in May–August and October–March, the lowest months. Those are among Bangkok's wettest months, with about 180 mm of rain a month against 10 mm in December.
3rd of 4
Of the 4 cities where we can rate Pale-Spotted Emperor sightings, Bangkok ranks 3rd at under 5%. The best odds are in Guangzhou (China, about 10%) and Singapore (Singapore, under 5%).
GBIF citizen-science records
It is estimated from how often the Pale-Spotted Emperor is recorded against all the insects logged in Bangkok (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.
