Katydids, or bush crickets, are large crickets in the family Tettigoniidae. There are more than 6,000 species within the family and these are often large insects. They have long antennae which distinguishes them from the closely related grasshoppers even though they are sometimes called Long-horned grasshoppers.

Bush crickets commonly eat plants and seeds but some species are carnivorous and will eat other animals.
