Abstract:
During the years 1976-1980 faunistic-ecological studies on orthopterans blattodeans and dermapterans were done in Trzebnicko-Ostrzeszowskie Hills. On 48 studied localities 44 species of Orthoptera, 6 species of Blattodea an d 4 species of Dermaptera have been found to occur. This amounts to more than 50% species of each of these orders known from Poland.
