Overview

Stauroderus scalaris, the large mountain grasshopper, is a species of 'short-horned grasshoppers' belonging to the family Acrididae subfamily Gomphocerinae.

Stauroderus scalaris faces severe population declines primarily due to habitat loss from agricultural intensification and urban development in its limited alpine and subalpine range. Climate change poses an additional threat by altering the temperature and precipitation patterns of its high-altitude grassland habitats.

Frequently asked questions

Why is Ladder Grasshopper classified as Endangered?
Ladder Grasshopper is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Stauroderus scalaris faces severe population declines primarily due to habitat loss from agricultural intensification and urban development in its limited alpine and subalpine range. Climate change poses an additional threat by altering the temperature and precipitation patterns of its high-altitude grassland habitats.
Where does Ladder Grasshopper live?
Ladder Grasshopper occurs in Albania, Andorra, Armenia, Austria, Bosnia & Herzegovina, and Bulgaria (plus 28 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Ladder Grasshopper?
The main threats to Ladder Grasshopper are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
