Gryllacrididae, commonly known as bush crickets or cave crickets, is a family of insects within the order Orthoptera. They are characterized by their long antennae, elongated bodies, and typically lack wings. These insects are primarily nocturnal and are often found in damp, dark environments such as caves, leaf litter, and under rocks. Members of Gryllacrididae are known for their unique sound production, which is used for communication, especially during mating. They are generally herbivorous, feeding on decaying plant material and fungi. This family includes various species that play important roles in their ecosystems as decomposers.
