This paper tests the recent published synthetic theory of biodiversity of Ritchie and Olff (1999) using data on parasitic Hymenoptera and soil living Diptera. Neither the predicted size dependent size ratio patterns, nor the left skewed species number-size class ratios, nor right skewed species richness-productivity patterns were found. It is concluded that the basic assumptions of the theory (self similarity of habitat, food, and resource distribution over ecological relevant scales) is not applicable at fine scales and to guilds of higher trophic levels. Whether in general the assumptions are applicable to plants and phytophages has to be decided by further studies.
