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 →

GBIF citizen-science records
It is estimated from how often the Ladder Grasshopper is recorded against all the insects logged in Pyrénées National Park (87 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.
