CC values were calculated for the genera Anopheles, Drosophila, and Glossina as well as between these three genera and between two outliers, Apis mellifera and Caenorhabditis elegans, and these two genera. For each combination, the minimum, mean, median, maximum CC values were calculated as well as the standard deviation and the number of species comparisons.
