In 3 days ~20% in a week ~40%
Trimerotropis verruculata, known generally as the crackling forest grasshopper or cracker grasshopper, is a species of band-winged grasshopper in the family Acrididae. It is found in North America. Its English common name comes from the distinctive cracking sound it makes as it flies. Its specific scientific name is derived from the Latin word for wart or excrescence and refers to its mottled rough appearance which probably provides camouflage on the exposed gravel, rock and ledge where it is often found.

GBIF citizen-science records
It is estimated from how often the Crackling Forest Grasshopper is recorded against all the insects logged in Olympic National Park (31 verified sightings from 2019 to 2026), 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.
