The Tettigoniidae family is a large and diverse group of insects commonly known as katydids or bush crickets. They are nocturnal, tree-dwelling insects, often with impressive sound-making abilities, using stridulation to produce their songs. These sounds are typically widespread in their ranges during the evening or nighttime hours, contributing significantly to the sounds of a tropical or temperate forest environment at twilight.
