With luck
About 10% of wildlife watchers report a Pale-Spotted Emperor sighting in Guangzhou on a given day, based on 46 verified sightings from GBIF citizen-science data. It is the 156th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

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.
