Possible
About 30% of wildlife watchers report a White Four Ring sighting in Minneriya National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 44 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

Of the 4 parks where we can rate White Four Ring sightings, Minneriya National Park ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Sinharaja Forest Reserve (Sri Lanka, about 30%).

GBIF citizen-science records
It is estimated from how often the White Four Ring is recorded against all the insects logged in Minneriya National Park (27 verified sightings from 2019 to 2026), 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.
