We present detailed data on correlation of the Shannon diversity index with members of Hill's and Hurlbert's parametric index family. The correlation reaches its maximum in both cases at a definite parameter value. These specified data on correlation are exploitable when applying the above diversity indices. Namely, in case of their parallel use with the Shannon index a strong correlation between the indices should be avoided. The investigations were carried out on sets of moth and fly collections.Moreover, we hypothesized that a smaller distance between so-called sensitivity profiles of diversity indices predicts a larger correlation between the indices concerned. Based on investigations of the sensitivity profile distance between the Shannon index and members of parametric diversity index family as a function of index parameter, we point out that on the whole the above hypothesis is true. This makes possible to estimate the correlation of two diversity indices omitting troublesome index calculations on a large set of abundance lists.
