Orphulella speciosa
In 3 days ~10%
Orphulella speciosa, commonly known as the slant-faced pasture grasshopper, is a species of short-horned grasshopper in the family Acrididae. Orphulella speciosa occurs east of the Rocky Mountain region all the way to the Coast of the Atlantic. It also occurs in the southern region of Canada and in the northern region of Mexico. O. speciosa inhabits areas of tallgrass and mixed grass prairies, often preferring areas of shorter grass that are interspersed throughout the prairie plant matrix, including grasses that have been grazed upon by larger animals.
At the southern end of the range (e.g., in Texas), adult O. speciosa are most abundant during August to October, with fewer adults present from May to December. In the northern extent of its range (e.g., New England) adult O. speciosa are most abundant during the months of July and August.
Orphulella speciosa has a very slanted face. The margins of the vertex of the head (the top of the head, located between the eyes) are less raised. The foveola (a small dent in the integument) is not distinct. The pronotal disks are found at the top of the first thoracic segment and are almost equivalent... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pasture Locust sighting in Washington on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1649th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pasture Locust in Washington on a given day, so our monthly data shows no clear season.
Only Washington, in our data
Washington is the only city on Wallace's Line with enough records to rate Pasture Locust sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Pasture Locust is recorded against all the insects logged in Washington (5 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.
