Advancing in time the following important aspect can be noticed: 1. Sprong species: Limnephilus decipiens K., Synagapetus mosely U., Silo pallipes F., hype ieducta H., Polycentropus flavomaculatus P., Plectrocnemia conspersa S., Plectrocnemia brevis M., Hydropsyche instabilis С 2. Summer species: Odontocerum albicornis S., Limnephilus flavicornis F., Limnephilus rhombicus L., Limnephilus extricatus M., Potamophylax nigricornis P., Rhyacophila tristis P., Rhyacophila pubescens P., Sericostoma personatum S., Rhyacophila fasciata H., Rhyacophila obliterata M. 3. Autumn species: Halesus digitatus S., Micropterna nycterobia M., Micropterna lateralis S., Limnephilus lunatus C, Anabolia laevis Z., Chaetopteryx fusca В., Limnephilus ignavus M., Ecclisopteryx madida M. THE ECOLOGICAL AND ZOOGEOGRAPHICAL CHARACTERISTICS OF THE TRICHOPTERAN FAUNA From a zoogeographical point of view Hungary is part of the Pannonicum and the Bükk Mountains belong to the Matricum. The components of the fauna of the area under investigation can be included in the following basic types of distribution: 1. Boreal species The larvea are expressly eurytherm ones, extreme eurytopes. They live in the streams of mountains, and often in springs too. They are members of the stony fauna (steinfauna) and are of Théophile type. Rhyacophila fasciata H., Rhyacophila obliterata Mac L. and Micropterna lateralis can be mentoined here. 104
