About 20% of wildlife watchers report a Pierella lena sighting in Amacayacu National Natural Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026.

Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Pierella lena sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Pierella lena sightings, Amacayacu National Natural Park ranks 3rd at about 20%, level with the leaders once rounded. The best odds are in Yasuní National Park (Ecuador, about 20%) and Manu National Park (Peru, about 20%).
GBIF citizen-science records
It is estimated from how often the Pierella lena is recorded against all the insects logged in Amacayacu National Natural Park (6 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.
