Katydids are insects belonging to the family Tettigoniidae, commonly known for their green coloration and leaf-like appearance. They are primarily found in warm, humid environments, such as forests and grasslands. Katydids are known for their distinctive sounds, produced by males to attract females, which can resemble the sound of a "katy-did"—hence their name. These insects are herbivorous, feeding mainly on leaves, flowers, and fruits. Katydids have long antennae and powerful hind legs, which they use for jumping. They play an important role in the ecosystem as both herbivores and prey for various predators, including birds and small mammals.
