Possible
About 20% of wildlife watchers report a Soldier Grasshopper sighting in Rosario on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 35th most-seen of the 82 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January and February
In those months about 30% of wildlife watchers report a Soldier Grasshopper in Rosario on a given day, against under 5% in April to October, the lowest months. Those are among Rosario's wettest months, with about 130 mm of rain a month against 20 mm in June.
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.
4th of 14
Of the 14 cities where we can rate Soldier Grasshopper sightings, Rosario ranks 4th at about 20%. The best odds are in Cochabamba (Bolivia, about 40%), Porto Alegre (Brazil, about 20%) and Curitiba (Brazil, about 20%).
Same family: Romaleidae
The closest relatives of the Soldier Grasshopper that you can see in Rosario (family Romaleidae, Lubber Grasshoppers) are Coryacris angustipennis (about 20%) and Staleochlora viridicata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Soldier Grasshopper is recorded against all the insects logged in Rosario (10 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.
