With luck
About 10% of wildlife watchers report a Belemnia eryx sighting in Manu National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 130th 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.
December
In that month about 20% of wildlife watchers report a Belemnia eryx in Manu National Park on a given day, against under 5% in January–March and July–August, the lowest months. That is one of Manu National Park's wettest months, with about 250 mm of rain against 60 mm in August.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Belemnia eryx sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Belemnia eryx sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Belemnia eryx that you can see in Manu National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Paraethria flavosignata (about 20%), Walker's Moth (about 20%) and Emeraldine (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Belemnia eryx is recorded against all the insects logged in Manu National Park (17 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.
