Aspects of butterfly zoogeography of some Pannonian island mountains

Specific geology and tectonic history of the Pannonian plain is pointed out. Lower mountains and hills, specific to the area, are highlighted. They most likely were islands in the period of Paratethys and Pannonian Sea: Malé Karpaty, Vertes, Bakony, Mecsek, Medvednica, Papuk, Fruška Gora and Avala. A head-to-head comparison has been done as well as a comparison with the site Mohács, a typical plain habitat in the Pannonian plain. The existence of specific elements of butterfly fauna of island mountains is discussed. According to the existing data from literature, the list of 163 butterfly species in explored area has been made. The degree of similarity between the explored island mountains has been calculated. A conclusion has been made about their faunal and zoogeographical liaison
