Moth communities were investigated in nine environment preservation areas in Kagawa Prefecture by the light trap method from 1991 to 1996. Total 936 species of 26 families were captured and species of Noctuidae, Geometridae and Pyralididae accounted for 80% of all. The moth communities were classified by the use of multivariate analyses, cluster analysis and quantification theory type IV, on binary data. Dissimilarity matrices of the 1-Cs index and the coefficient of disagreement were used. Two areas, where the number of moth species were scanty, were distinguished from others by either the cluster analysis or the quantification analysis on the dissimilarity matrix of the 1-Cs index, while the analyses on the matrix of the disagreement coefficient was effective to separate groups of areas having many species. This discrepancy of the results was discussed from the viewpoint of the difference in the property between two indices
