With luck
About 10% of wildlife watchers report a Chiapas White sighting in Yasuní National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 89th most-seen of the 203 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a Chiapas White in Yasuní National Park on a given day, against under 5% in January, March–June and September–October, the lowest months.

Across all the parks we cover, that three-hour window holds the most Chiapas White sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.

Of the 5 parks where we can rate Chiapas White sightings, Yasuní National Park ranks 5th at about 10%. The best odds are in Rincón de la Vieja National Park (Costa Rica, about 20%), Tambopata National Reserve (Peru, about 20%) and Manu National Park (Peru, about 10%).
GBIF citizen-science records
It is estimated from how often the Chiapas White is recorded against all the insects logged in Yasuní National Park (10 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.
