Rare
Under 5% of wildlife watchers report a Copaxa decrescens 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.
February
In that month about 10% of wildlife watchers report a Copaxa decrescens in São Paulo on a given day, against under 5% in March to January, the lowest months. That is one of São Paulo's wettest months, with about 180 mm of rain against 35 mm in August.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Copaxa decrescens sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only São Paulo, in our data
São Paulo is the only city on Wallace's Line with enough records to rate Copaxa decrescens sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Copaxa decrescens 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.
