With luck
About 10% of wildlife watchers report a Charcoal-Winged Percher sighting in Chennai on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 237th most-seen of the 376 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.
June and August–November

GBIF citizen-science records
It is estimated from how often the Charcoal-Winged Percher is recorded against all the insects logged in Chennai (10 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.
