HOW IS THE CRICKETS' SOUND MADE?

Crickets are related to katydids (family Tettigoniidae), which are nocturnal insects comprising about 6,000 different species. Another name given to katydids is bushcrickets; you can identify katydids and long-horned grasshoppers by their threadlike antennae, thick ovipositor (the structure used for laying eggs at the females’ posterior) and large hind legs.

Crickets and katydids make species-specific calls to mark out territory, attracting mates or for defensive purposes against predators. They produce their characteristic sound or rasping song by rubbing the ridged forewings together.
