 abstract={A comparison of leafhopper (Homoptera – Auchenorrhyncha) communities in two meadows differing in the degree of their diversification showed that the more diversified habitat was richer in species, and the number of individuals in it was doubled. However, as a result of the strong pression of the predators (numerous in all layers of the diversified habitat) the average life span of the leafhoppers was several times shorter, and their population density was less than a half of that in the meadow with simpler trophic relationship.},
