Tettigoniidae, commonly known as katydids or bush crickets, are distinguished by their elongated bodies, long antennae, and leaf-like wings. Predominantly nocturnal, they inhabit forests and grasslands, where they play a crucial role in controlling pest populations. Their unique ability to communicate through stridulation makes them a fascinating study of acoustic communication in nature.

The family Tettigoniidae, commonly known as katydids or bush crickets, is native to a wide range of regions globally. They are found on every continent except Antarctica, with significant populations in tropical and temperate regions. The highest diversity of species is observed in tropical forests of Central and South America, Africa, and Southeast Asia.

Tettigoniidae typically inhabit environments that provide ample vegetation, as they are predominantly herbivorous. They thrive in various habitats such as forests, grasslands, and shrublands. The species are adapted to both temperate and tropical climates, with some species found in arid environments.

Katydids play a crucial role in their ecosystems as both prey and predator. They are primarily nocturnal and are known for their leaf-like appearance, which provides camouflage from predators. As herbivores, they feed on leaves, flowers, bark, and occasionally small insects. Their presence is vital for the pollination of certain plants and as a food source for birds, mammals, reptiles, and other insects.
