Stauroderus scalaris, the large mountain grasshopper, is a species of 'short-horned grasshoppers' belonging to the family Acrididae subfamily Gomphocerinae. Stauroderus includes the following subspecies: Stauroderus scalaris demavendi Popov, G.B., 1951
It is the largest species of grasshopper in Europe. The basic coloration of the body varies from pale or bright green to yellow, with dark-brownish wings and tegmina. Femora of hind legs vary from yellow to reddish. In the males median and ulnar wing cells are quite large, with parallel veins. The adults usually live in colonies and the males emit whirring stridulations to attract females.
These grasshoppers can be encountered from July through September especially in high-altitude alpine meadows and pastures. This species is present in most of Europe, in the Near East, and in the eastern Palearctic realm. Wikipedia →

Possible
About 30% of wildlife watchers report a Ladder Grasshopper sighting in Aigüestortes National Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 256 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Ladder Grasshopper in Aigüestortes National Park on a given day, against under 5% in March–May and October, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Ladder Grasshopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 7
Of the 7 parks where we can rate Ladder Grasshopper sightings, Aigüestortes National Park ranks 2nd at about 30%. The best odds are in Mercantour National Park (France, about 40%).

GBIF citizen-science records
It is estimated from how often the Ladder Grasshopper is recorded against all the insects logged in Aigüestortes National Park (38 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.
