Abstract

Dung beetles are insects that provide a large-scale ecosystem service worldwide through their role in the decomposition of manure from livestock, thereby providing a series of environmental services, such as nutrients recycling, control of internal parasites of live- stock whose eggs are in the feces, soil aeration, spreading of seeds and maintenance of ecological balance. Dung beetles are broadly classified according to their nesting behav- ior in three categories as telecoprids, paracoprids and endocoprids. Telecoprids are the rollers that make balls from feces and roll them into the ground; paracoprids are the tunnellers that bury the dung balls at different depths, forming galleries in the ground below or next to the food source and endocoprids, who are the dwellers that raise their larvae inside feces. There are 10 native species of dung beetles recorded in Chile, apart from 10 species of Aphodiinae, plus two introduced species, such as Onitis vanderkelleni and Onthophagus gazella. Dung beetles species were prospected in La Araucania Region and registered Homocopris torulosus, Frickius variolosus, Podotenus fulviventris and Aphodius pseudolividus. We found that species from genus Homocopris, Podotenus and Aphodius were distributed from 0 to 2000 m above sea level, while F. variolosus was distributed over an altitude of 350 m.
