Rare
Under 5% of wildlife watchers report a Geyser Grasshopper sighting in Yellowstone National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 102nd most-seen of the 160 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Geyser Grasshopper in Yellowstone National Park on a given day, against under 5% in October to June, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Geyser Grasshopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Yellowstone National Park, in our data
Yellowstone National Park is the only park on Wallace's Line with enough records to rate Geyser Grasshopper sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Geyser Grasshopper is recorded against all the insects logged in Yellowstone National Park (11 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.
