With luck
About 10% of wildlife watchers report an Emerald-Patched Cattleheart sighting in Manu National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 103rd most-seen of the 366 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.
June, September and December
In those months about 20% of wildlife watchers report an Emerald-Patched Cattleheart in Manu National Park on a given day, against under 5% in April–May, July–August and October–November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Emerald-Patched Cattleheart sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 parks where we can rate Emerald-Patched Cattleheart sightings, Manu National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Tenorio Volcano National Park (Costa Rica, about 10%) and Tambopata National Reserve (Peru, about 10%).
GBIF citizen-science records
It is estimated from how often the Emerald-Patched Cattleheart is recorded against all the insects logged in Manu National Park (13 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.
