Preface

In past years there have been several unsuccessful attempts to arrange a symposium on Trichoptera. Letters from fellow workers suggested that now might be an appropriate time, and that a symposium should be held in Lunz.

Today it is clear that large congresses are losing their value because of the difficulty of attending all relevant lectures and of finding colleagues. In consequence, small symposia for specialist groups are becoming increasingly important. As I felt that the success of such a symposium must depend on the suggestions from its potential members, I sent out in April 1973, together with a first circular, a questionnaire, asking for opinions on time and length of the symposium, numbers of participants, types of communication, interests within Trichopterology, and lan­guages which should be used. The majority of answers suggested the following: The number of participants should be between 20 and 50, and the duration, excluding excursions, should be three to five days; main interests were in ecology and systematics, but there were also interests in physiology, behaviour, zoogeography, morphology, cytotaxonomy and evolution. There was a clear preference for local excursions. Languages should be English, French and German, with a preference for English. The symposium should consist of both formal papers and informal progress reports, with adequate time for discussion.

The arrangements have therefore been based on these results. The symposium which was held in the rooms of the House 'Zellerhof', was opened on the morning of 16th September. Two and a half days were devoted to lectures, and two half days to discussions. On the second day, a collecting excursion was made to the nearby valley of Seetal. In the evening of the first day the Mayor of Lunz, Mr. ENGELBERT HAGER, gave a reception in the rooms of the restaurant on the shore of the lake, and in the evening of the third day the four hundred years old building Amonhaus which is the Town Hall and local museum, was visited under the conduction of the well-known writer and historian, Mrs. ELISABETH KRAUS-KASSEGG.

In the discussions the following topics were considered under the presidency of G. MARLIER:

1. Better information (Journal, Newsletter, etc.). It was proposed to start a Newsletter which would contain such useful information as: addresses of research workers, offers and demands for material and collaboration, etc. MALICKY would compile such a Newsletter, with the assistance of CRICHTON, at least for the first two numbers. If interest were maintained a continuation was possible and would be discussed later. The following workers were willing to act as correspondents for their countries and to help with the distribution of the Newsletter: BOTOSANEANU (Romania), BOURNAUD (France), CRICHTON (Great Britain), FLINT (USA, South America), FLORIN (Switzerland), HIGLER (Netherlands), KUMANSKI (Bulgaria), MALICKY (Austria, Greece), MARINKOVIC (Yugoslavia), MARLIER (Belgium), MORETTI (Italy), NEBOISS (Australia, New Zealand), NIELSEN (Denmark), NovAK

(Czechoslovakia), SOLEM (Norway), SZCZESNY (Poland), TERRA (Portugal), UJHELYI (Hungary), WIGGINS (Canada), ZINTL (German Federal Republic).

A journal for Trichopterology seemed not realizable because of insurmountable economic problems.

2. Continuation of the Trichopterorum Catalogus. HIGLER reported on his efforts in this respect and asked for collaboration.

3. Identification literature, mainly for larvae. Identification works for Trichoptera larvae were urgently needed. MALICKY explained, in the absence of ILLIES, the project 'Limnofauna Mundi' which would consist of a number of books, edited by ILLIES, for the identification of all stages of aquatic animals of the world, but only, in principle, to genera. MALICKY asked for collaboration in the larval part of the Trichoptera volume; the adults would be treated by himself. Several objections were made to this type of identification book, mainly in connection with the continuing lack of information and the very different levels of knowledge in different regions of the world. It was agreed that it would be preferable to establish separate regional keys instead of a global one, but they could be collected later into a single volume.

HILEY reported on keys for larvae in Britain on which he was working, MARLIER reported about a similar project for Africa.

4. Problems concerning the extinction of species and populations. Several exam­ples were reported from various countries. It seemed that the danger of extinction of single species of caddis-flies was not important except perhaps for endemics of small islands. Conservation of biotopes was much more important. BOTOSANEANU agreed to prepare a note concerning this point for the Newsletter.

5. Faunistics. Information was presented about the European Invertebrate Survey and the Sixth International Symposium on Entomofaunistics in Central Europe which would be held in Lunz am See in September 1975.

6. Speciation and evolution. BOTOSANEANU proposed collaboration on an interna­tional basis for the study of Wonnaldia occipitalis (Philopotamidae) which is one of the most promising objects for this kind of work.

7. Continuation of meetings, establishing a permanent organization committee. The continuation of this kind of meetings was agreed to CRICHTON would organize the next symposium in Reading (Great Britain) in 1977 to fit in with the SIL congress in Denmark. BOTOSANEANU, MALICKY and WIGGINS would assist in the organization. The other proposal, to hold it in or near Washington D.C., in connection with the International Congress of Entomology in 1976, was rejected because of the financial problems of attendance for many workers.

Finally, I wish to express my gratitude to all those who helped in the organization of the meeting: above all, the Mayor of Lunz, Mr. HAGER, and his family; Dr. CRICHTON who helped with the correction of English texts; my wife; my father, Mr. J. T. MALICKY; and my collaborators of the Lunz Biological Station of the Austrian Academy of Sciences. I did my best to organize the meeting, but it was really made by the participants from 17 countries, by their presence, by presiding at sessions, by presenting papers, and by contributing to the discussions. My thanks are due to them all.
