Seventy-four species of orthopterans are listed by the World Conservation Union (IUCN).
Two of these species, the central valley grasshopper and Antioch dunes shieldback, are listed as Extinct, or no longer alive. The Oahu deceptor bush cricket is listed as Extinct in the Wild, or alive only in an artificial environment. Eight species are listed as Critically Endangered, another eight as Endangered, and 50 more species are listed as Vulnerable. Critically Endangered means facing an extremely high risk of extinction in the wild. Endangered means facing a very high risk of extinction in the wild, and Vulnerable means facing a high risk of extinction in the wild.
The single most important threat to all orthoptrans is habitat destruction. This is especially true for species that are found only in small geographic areas. The introduction of ants, cats, and rats, especially on islands such as New Zealand, is a serious threat to many orthopteran species.
