In 3 days ~50% in a week ~80%
Sphenarium purpurascens (Spanish: Chapulín de milpa and Portuguese: Gafanhoto-do-milho, i.e., corn-field grasshopper), is a grasshopper species in the genus Sphenarium found in Mexico and Guatemala. The harvesting of the grasshoppers in Mexico for human consumption can be a way for managing pest outbreaks. Such strategies allow decreased use of pesticide and create a source of income for farmers. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cornfield Grasshopper is recorded against all the insects logged in Mexico City (1,305 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.
