ABRAHAM, L.: ALDERFLY AND LACEWING FAUNA OF THE VILLANY HILLS 261 number of individuals by any of the sampling techniques, either by netting or light trapping. The Villány Hills is a single hill range spreading in east-west direction, thus this territory gave an excellent opportunity to study the habitat preference of lacewings (ZELENY 1965, 1984). The mean temperature and the relative air humidity show sharp differences due to the south-north direction of slopes and to the solar radiation, while the natural vegetation forming almost zones or mosaics is influenced by the thickness of soil layer as well, besides the above mentioned factors. Fig. 10. shows the schematic transverse profile of the Villány Hills range from south to north. Urban areas can now be found at the foot of the hills, even in the Dráva Lowland. This territory is covered by different urban and agricultural habitats, parks, front and back gardens, rows of planted trees and orchards. Conwentzia pineticola, Coniopteryx pygmaea, Peyerinhoffina gracilis, were recorded only in the urban zone by netting on the foliage of planted Scotch pine, as they are strictly associated with pine trees. At the foot of the hill range vineyards are well spread, sometimes they reach as far up as the top of the hills. Among the species caught, only Wesmaelius subnebulosus seems to be related with this area. By studying the occurrence of the species in Hungary, it appears that it can be regularly found in higher abundance in agricultural habitats (STELZL, DEVETAK 1999) than in native habitats. At the southern feet of the hills there are loess grasslands and spontaneously colonising trees and scrubs; this habitat is characteristic especially for the slope of Szársomlyó Hill. In this habitat Aleuropteryx umbrata, Coniopteryx arcuata and Distoleon tetragrammicus were caught. Fig. 10.
