Insects in the
cricket family Tettigoniidae are commonly called
katydids or
bush crickets. More than 6,400
species are known. They are also known as
long-horned grasshoppers, to distinguish them from the
Caelifera, the true or short-horned grasshoppers. Part of the suborder
Ensifera, it is the only family in the superfamily Tettigonioidea.
