Species Profile
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.
