The Rattle Grasshopper (Psophus stridulus) measures around 2-3,5 cm and has orange-colored hind wings, recognizable however, only in flight. Its name comes from another particular and recognizing characteristic, the buzzing sound generated during the flight, which is used both to frighten enemies and as a mating ritual. Grasshoppers and cicadas are the groups of insects with the largest variety of sounds, which can vary often by region - analogous to the dialects of people. The characteristic noises are often much better to determine the species than their appearance. The Rattle Grasshopper is protected. It loves dryness and heat, and lives in the entire Alpine space on lean meadows and pastures up to high altitudes.
