About 10% of wildlife watchers report a Plain Flashwing sighting in Kozhikode on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 75th most-seen of the 138 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Plain Flashwing is recorded against all the insects logged in Kozhikode (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.
