About 10% of wildlife watchers report a Pierella nereis sighting in São Paulo on a given day, based on 62 verified sightings from GBIF citizen-science data. It is the 124th most-seen of the 832 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.
October to February
In those months about 10% of wildlife watchers report a Pierella nereis in São Paulo on a given day, against under 5% in March to September, the lowest months. Those are among São Paulo's wettest months, with about 170 mm of rain a month against 35 mm in August.

GBIF citizen-science records
It is estimated from how often the Pierella nereis is recorded against all the insects logged in São Paulo (62 verified sightings), 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.
