Under 5% of wildlife watchers report a Dusky Owl-Butterfly sighting in São Paulo on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 751st most-seen of the 832 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dusky Owl-Butterfly in São Paulo on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Dusky Owl-Butterfly is recorded against all the insects logged in São Paulo (5 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.
