About 10% of wildlife watchers report a Blue Glassy Tiger sighting in Singapore on a given day, based on 477 verified sightings from GBIF citizen-science data. It is the 60th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
January–March and June

GBIF citizen-science records
It is estimated from how often the Blue Glassy Tiger is recorded against all the insects logged in Singapore (477 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.
