pastures which were formerly sampled. As it was experienced in very dry sites like localities in Afghanistan that not only coprophagous species are collectible on dung but all those flies which are attracted by the higher humidity on or just beside dung (e.g. sample 8). A comparison of the species composition of the dipterous assemblages with those on dung of other hoofers does not indicate any significant difference, i.e. any species on red deer dung may occur on sheep dung. It is probable that only the assemblages on horse dung contain species which develop mainly though not exclusively in horse dung. Samples of these sizes (with these numbers of specimens) are not large enough to represent more than the dominant-subdominant species of the assemblages and representatives of some rare species randomly. This is why the differences are seemingly so large between the samples. Table 1.
