There are two species of Cordulegastridae in Hungary. The habitats of the commoner species{Cordulagaster bidentatus) can be found in the Soproni, Kőszegi, Bakony, Zempléni and Mátra Mountains. But the occurrences of Cordulegaster heros were known from the Soproni Mountains, Őrségi Hills, and the Mecsek Mountains. So the new data of the species in the Zselic Hills is remarkable from faunistical and nature conservation point of view
