Possible
About 20% of wildlife watchers report a Pierella lena sighting in Manu National Park on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 26th most-seen of the 366 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Pierella lena in Manu National Park on a given day, against under 5% in January, May and August, the lowest months. That is one of Manu National Park's driest months, with about 80 mm of rain against 290 mm in February.
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, Manu National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Yasuní National Park (Ecuador, about 20%).
Same genus: Pierella
The closest relatives of the Pierella lena that you can see in Manu National Park (genus Pierella) are Pierella rhea (about 10%), Pierella hortona (about 10%) and Pierella dracontis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pierella lena is recorded against all the insects logged in Manu National Park (33 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.
