Possible
About 20% of wildlife watchers report a Mountain Grasshopper sighting in Kosciuszko National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 105 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Mountain Grasshopper in Kosciuszko National Park on a given day, against under 5% in March to October, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Mountain Grasshopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Kosciuszko National Park, in our data
Kosciuszko National Park is the only park on Wallace's Line with enough records to rate Mountain Grasshopper sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Acrididae
The closest relatives of the Mountain Grasshopper that you can see in Kosciuszko National Park (family Acrididae, Short-horned Grasshoppers) are Chameleon Grasshopper (about 40%), Giant Green Slantface (about 20%) and Wingless Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mountain Grasshopper is recorded against all the insects logged in Kosciuszko National Park (17 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.
