Jumping plant lice (Hemiptera: Psylloidea) of the Ojców National Park (Southern Poland)

The paper lists psyllids (Hemiptera: Psylloidea) found in and around the Ojców National Park and discusses some selected species. Of the 46 confirmed species, representing the families Aphalaridae, Liviidae, Psyllidae and Triozidae, 44 are reported for the first time from the Ojców National Park. The largest group of psyllids is constituted by taxons related to forests and meadow and herbaceous communities. The following species are of particular interest. Craspedoplepta flavipennis (Foerster, 1848), a species characteristic of montane and subalpine altitudes, has its northern limit in Poland. The boreal-upland Cacopsylla nigrita (Zetterstedt, 1828) and Craspedoplepta malachitica (Dahlbom, 1851) are considered to be typical steppe species in Poland.
