A study of flora and fauna that concerned the groupings of parasitoids from the subfamily Pimplinae (Hymenoptera, Ichneumonidae) in the agricultural landscape with three levels of mosaic structure (low, medium and high) was used. The obtained data were analysed in terms of quality and quantity using 12 similarity measures and the results were presented in dendrograms. Later on, Mantel test was applied to verify the hypothesis on the similarity of the measures. Based on the dendrograms the similarity measure groups were specified. One of them contains Bray, Jaccard and Kulczyński measures, while the others include Horn and Morisita, Binomial and Gower, Euclidean and Manhattan, Chao and Mountford measures. The Canberr measure did not show any similarity to any of the analysed measures. The measures could be interchanged within a group during the study. The most suitable measures for comparing structural units of biocenoses turned out to be Bray, Jaccard and Kulczyński coefficients.
