With luck
About 10% of wildlife watchers report a Soldier Grasshopper sighting in São Paulo on a given day, based on 121 verified sightings from GBIF citizen-science data. It is the 58th 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 50%, if each day is a fresh chance.
January and February
In those months about 20% of wildlife watchers report a Soldier Grasshopper in São Paulo on a given day, against under 5% in June to August, the lowest months. Those are among São Paulo's wettest months, with about 200 mm of rain a month against 35 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Soldier Grasshopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
11th of 14
Of the 14 cities where we can rate Soldier Grasshopper sightings, São Paulo ranks 11th at about 10%. The best odds are in Cochabamba (Bolivia, about 40%), Porto Alegre (Brazil, about 20%) and Curitiba (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Soldier Grasshopper is recorded against all the insects logged in São Paulo (121 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.
