Beetles (Geotrupidae, from Greek geos, earth and trypetes, drilling) are beetles family. They are generally called fertilizers or dung beetles.
Most of them dug out corridors, tunnels and nests in the country where they lay their eggs and larvae. They are typically saprophagous, supplying their nests with leaf litter (often rotting), occasionally copropagous. They lay the eggs in or below the source of their future food, which they buried in the ground and developing larvae then feed on these supplies. Corridors of some species reach as deep as 2 meters.
Some species communicate by stridulation, rubbing certain parts of the body together.
