Auchenorrhyncha represents a group of sucking herbivores belonging to the hemipterans. They are an important component of terrestrial ecosystems, many species feed on a certain plant genus or even on one single plant species. In Poland, 514 species of Auchenorrhyncha have been recorded so far. From this number 135 species are recognized as rare, found only in a few places. Four species: Cicadetta montana (scop.), Cicadetta podolica (elchw.), Aphrophora major uhler and Aphrophora similis Leth. are endangered and should be protected. We suggest preserving xerothermic swards for Cicadetta montana and C. podolica, peatbogs and marshes for Aphrophora major and A. similis. A short morphological, ecological and chorological characteristics of these species are also given.
