When the adult beetle emerges, its transformation from egg to grub to pupa to adult is complete. (This process of going through different, changing forms to develop into an adult is called metamorphosis ͘Ϳ EŽǁ the new adult beetle begins looking for a dead animal of its own so it too can start a family.

Once a dead mouse is found, the male and female beetles hollow out a small chamber in the soil by the mouse. Then the mother beetle lays her eggs in the chamber. Both the mother and father guard their nest.
