Schistocerca cancellata
In 3 days ~60% in a week ~90%
Schistocerca cancellata is a species of locust in the subfamily Cyrtacanthacridinae. It is the major swarming species in subtropical South America. This species shows typical locust phase polymorphism. Solitarious nymphs are green, but gregarious ones are yellow with a black pattern. There are morphological differences between solitarious and gregarious adults. For many years the two phases were believed to be different species and the gregarious form was mistakenly identified as S. paranensis.
The solitary phase is found in South America between 18°S and 35°S. Plagues originate in a desert and semi-desert zona permanente in northwest Argentina, southeast Bolivia and western Paraguay, when good rains allow successful breeding, followed by gregarisation. Swarms of gregarious adults may then migrate into crop growing regions. Wikipedia →

Possible
About 30% of wildlife watchers report a South American Locust sighting in Cochabamba on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 31 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February and March
In those months about 50% of wildlife watchers report a South American Locust in Cochabamba on a given day, against under 5% in May to December, the lowest months. Those are among Cochabamba's wettest months, with about 75 mm of rain a month against 5 mm in July.
Yes
Of the 2 cities where we can rate South American Locust sightings, Cochabamba has the highest daily chance: about 30%. Next come Santiago (Chile, about 10%).
Same order: Orthoptera
The closest relatives of the South American Locust that you can see in Cochabamba (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Soldier Grasshopper (about 40%) and Tropical House Cricket (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the South American Locust is recorded against all the insects logged in Cochabamba (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.
