With luck
About 10% of wildlife watchers report a Leuce Yellow sighting in Curitiba on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 73rd most-seen of the 177 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.

GBIF citizen-science records
It is estimated from how often the Leuce Yellow is recorded against all the insects logged in Curitiba (13 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.
