A total of 9,982 specimens were captured, belonging to the families Scarabaeidae and Trogidae, and representing 21 genera and 50 species. The genera Ataenius Harold, Onthophagus Latreille and Aphodius Illiger represented 48% of the species of Scarabaeidae. Species richness was found to decrease with increasing altitude; there were 36 species at 1000 m asl, 27 species between 1200 and 1300 m asl, and 26 species at 1400 m asl. Abundance along the altitudinal gradient follows a pattern of few abundant species and many species with few specimens. Beetle activity is related to precipitation. In the nine communities studied, species richness was observed to increase when precipitation was greater than 100 mm at the beginning of the rainy season. On the landscape scale, there were 44 species during the rainy season, 22 during the windy nortes season, and 24 during the dry season. In terms of trophic guild, 40% of the beetles captured were saprophagous that feed on decomposing organic material from plants and 60% were saprophagous that feed on decomposing organic material from animals (30% necrophagous, 26% coprophagous, 4% telio-necrophagous).

This study investigated the effect of variation in quality of herbivore dung on the survival and reproduction of coprophagous insects. Seasonal variation was recorded in physical and chemical characteristics of zebra, wildebeest and impala dung. Dung was collected from free- ranging animals grazing in natural habitat in Mkuzi Game Reserve, a hot summer-rainfall region of South Africa. Interspecific differences in dung were related to the feeding ecology, digestive physiology and size of each species. Seasonal changes in water and nitrogen content of dung were related to patterns of rainfall and hence pasture growth. Dung moisture was significantly correlated with the amount of rain that fell in the preceding 2 weeks for wildebeest, in the preceding 4 weeks for impala and in the period 2-6 weeks before collection for zebra dung. Seasonal variability in wildebeest dung affected the reproductive rate of the dung beetle Euoniticellus intermedius (Reiche). Egg production at 25- degrees-C ranged from 0.1 per female per week in winter dung to 12.1 in summer dung, and was significantly correlated with dung moisture. Euoniticellus intermedius and the African buffalo fly Haematobia thirouxi potans (Bezzi) could not breed in fresh wildebeest dung of 62% water content. However when the water content was raised to 68% and above, breeding by Euoniticellus intermedius increased; and at moisture contents of 73% and above, buffalo fly size increased and survival improved. Higher water content was correlated with an increase in availability of dung fluid, the component of dung used by these insects.
