Rare
Under 5% of wildlife watchers report a Red-Bordered Satyr sighting in Mexico City on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 207th most-seen of the 557 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.
August and September
In those months about 10% of wildlife watchers report a Red-Bordered Satyr in Mexico City on a given day, against under 5% in October to July, the lowest months. Those are among Mexico City's wettest months, with about 150 mm of rain a month against 5 mm in December.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Red-Bordered Satyr sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nymphalidae

GBIF citizen-science records
It is estimated from how often the Red-Bordered Satyr is recorded against all the insects logged in Mexico City (31 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.
