The Tettigoniidae family, called the "Long-Horned Grasshoppers", includes 20 subfamilies. One of the more rare species of Austria is the Saga pedo, "Matriarchal katydid", which is a carnivore and parthenogenetic grasshopper.

In 1997 a change in the subfamily structure, the Tettigoniinae (Otte, 1997), was proposed and recognized. The subfamily is now holding all species from the old subfamily Decticinae and some species from other subfamilies. Sources: Singing Insects of North America and Orthoptera Species File Online.
