It is the 188th 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 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Idaea gemmaria is recorded against all the insects logged in Chennai (12 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.
