Ábrahám Levente: Alderfly (Megaloptera) and lacewing (Neuroptera) fauna of the Villány Hills, South Hungary. - A Villányi-hegység nagyszárnyú (Megaloptera) és recésszárnyú (Neuroptera) faunája.

ÁBRAHÁM, L.: ALDERFLY AND LACEWING FAUNA OF THE VILLÁNY HILLS 263 At the feet of the northern slopes the microclimate diverges negatively from the average climate. The natural vegetation is characterised by fresh deciduous woodlands, Illyrian beech (e.g. Kistótfalu, Kopasz-Hill) and oak-hornbeam woodlands (e.g. Vokány, Trinitás-forest), because the ground water filtrates down to the valleys opening towards the north. These habitats are cooler than their surroundings and are characterised by Coniopteryx tineiformis, Drepanopteryx phalaenoides, Hemerobius marginatus, Chrysotropia ciliata, Nothochrysa fulviceps. At the feet of the northern part of the hills there is only one small brook, PogányVillány streamlet, running through two fish ponds. Alongside its bank and the shore of the ponds there are willow and alder riverine forests. Alderfly, Sialis lutaria and sponge fly, Sisyra fuscata were recorded in this area. Coniopteryx aspoecki, a hygrophilous species, also lives here, because it is associated with riverine willow habitats found near water courses. The abundant species with wide ecological spectrum occurred in the entire area of the hills. Fig.: 11. shows the distribution of the relative frequency of the common species in different habitats. It seems that Coniopteryx esbenpeterseni, Hemerobius micans, Chrysotropia ciliata are mainly hygrophilous species. We can draw the conclusion, as shown in Fig. 11, that the distribution of the relative frequency of species better characterises different habitats influenced both abiotically and biotically than mentioning only one or two characteristic species.
