Proceedings of the Third International Symposium on Trichoptera : Perugia July 28–August 2, 1980

G.P. MORETTI The Triennial Symposium of Trichoptera would seem to have become a regular event on the calendar. Initiated by Prof. Malicky at Lunz in Austria in 1974, they continued at Reading in England in 1977 (Convenor: Dr M.I. Crichton), the last, this year, took place in Perugia, Italy (Convenor: Prof. G.P. Moretti) and the next will be hosted by Dr J.C. Morse in Clemson, U.S.A. in 1983. The most outstanding points of the 3rd International Symposium on Trichoptera held at Perugia from July 28 to August 2, 1980 were I) the high number of participants; 2) the extent, scientific interest and coverage of the papers presented and 3) the warmth and immediate contact which drew everyone together from the first moment. Twenty-one nations (Australia, Austria, Belgium, Bulgaria, Canada, Czechoslavakia, Denmark, France, Germany-F.G.R., Germany-G.D.R., Hungary, Iceland, Italy, Mexico, Netherlands, Poland, Spain, Sweden, Switzerland, United Kingdom, United States) were represented by a total of 63 trichopterologists who presented 54 papers and 8 posters during in 8 sessions chaired by M.I.
