With luck
About 10% of wildlife watchers report a Ceylon Blue Glassy Tiger sighting in Kuala Lumpur on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 224th most-seen of the 323 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–April, June and October

GBIF citizen-science records
It is estimated from how often the Ceylon Blue Glassy Tiger is recorded against all the insects logged in Kuala Lumpur (7 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.
