These usually two were rollers and rest were tunnelers. Addionally coprophagous and rarely necrophagous beetles belong to other beetles associated with animal excrement collected the family Scarabaeidae and Sub- family Scarabaeinae of belong to family Histeridae (3 unidenfied species) and order Coleoptera and are categorized into tunnelers family Scarinae (1 Clivina sp.) were recorded. (paracoprids), dwellers (endocoprids), or rollers (telecoprids) (Figure 1) (Haler and Mahews 1966; The present work is a head start to record the diversity of Hanski and Cambefort 1991). Tunnelers consume the dung beetles in the Jnana Bharathi campus carried as a dung pat and burrow into the soil beneath the pat; rapid diversity survey, serving as an impetus for further dwellers consume the manure pat and deposit eggs in detailed studies. the manure, or in the soil near the surface; Rollers tend to break the pat into brood balls that are rolled to a References suitable site and buried.
