Tettigoniidae is the family of insects commonly known as katydids or long-horned grasshoppers. They are characterized by their long, thread-like antennae, often exceeding their body length. Most species are green, providing excellent camouflage among foliage. Many Tettigoniids produce distinctive songs by rubbing their wings together, a process called stridulation. They are generally herbivorous, though some may also consume insects. Their songs fill the night with distinct calls. They are vital components of many ecosystems.
