In 3 days ~10% in a week ~20%
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.

Under 5% of wildlife watchers report a Crackling Forest Grasshopper sighting in Portland on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 378th most-seen of the 507 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Crackling Forest Grasshopper in Portland on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Crackling Forest Grasshopper is recorded against all the insects logged in Portland (8 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.
