With luck
About 10% of wildlife watchers report a Corydalus affinis sighting in Manu National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 246th most-seen of the 366 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Corydalus affinis in Manu National Park on a given day, against under 5% in October and December–July, the lowest months. That is one of Manu National Park's driest months, with about 60 mm of rain against 290 mm in February.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Corydalus affinis sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Corydalus affinis sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Corydalus affinis is recorded against all the insects logged in Manu National 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.
