THE INSECT WORLD OF THE BAKONY MOUNTAINS INTRODUCTION Insects live all over the world, they run to more than three-quarters of the at present described species of animals. At different estimations the whole number of their species is between 10 and 30 millions, from which we know 1-15 millions nowadays. There are 35 thousand species of insects in our country, from which 20-25 thousand live also in the Bakony Mountains. In this small brochure - conforming to the exhibition and to the typical habitats of the Bakony Mountains - we try to give as much information as possible about these interesting animals. At the habitats we mention not only the frequent species, but also the rarities of the Bakony Mountains. We give also the Hungarian and scientific name of the species discussed. Illustrations and colour photos help to identify certain species. The species written with boldface characters can be seen in the exhibition of the Natural History Museum of Bakony Mountains in Zirc, where also their German and English names can be found. THE ZOOGEOGRAPHICAL DIVISION OF THE BAKONY MOUNTAINS The natural geographical Bakony Mountains with an extent of 4 000 km

2 is the biggest landscape of the Transdanubian Range. It is bordered by the Lake Balaton and the plain of Mezőföld in the south and southeast, by the Vértes Mountains in the east, by the Little Plain in northwest and west. The Bakony Mountains as a zoogeographical unit is part of the district of the Hungarian Mountain Range (Matricum), which belongs to the Central-Danubian faunal region, and it is the same as the faunal area, called Bakonyicum. Jenő Papp (1968) was the first person who divided the Bakony Mountains into small areas with the help of 75 so called colouring species of animals. He distinguished five areas: the Balaton-uplands, the Keszthelyi Mountain, the southern Bakony Mountains, the northern Bakony Mountains, and the eastern Bakony Mountains (1.illustration) which are accepted even today. During the research of certain insect families further divisions had to be made. Thus, inresearching the fauna of the digger wasps Pál Benedek (1979) suggested the separation of a further small faunal area, which is called 'Balatoni Riviéra'. Mihály Medvegy (1987) divided the area into northern, southwestern and southeastern parts
