With luck
About 10% of wildlife watchers report a Yellow Palm Dart sighting in Singapore on a given day, based on 177 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
March to December
In those months about 10% of wildlife watchers report a Yellow Palm Dart in Singapore on a given day, against under 5% in January and February, the lowest months.

GBIF citizen-science records
It is estimated from how often the Yellow Palm Dart is recorded against all the insects logged in Singapore (177 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.
