Found throughout Britain, the common sexton beetle is a carrion or burying beetle - it buries, and lives off, small carcasses. In fact, it can detect the scent of rotting flesh a mile away.
As carrion beetles eat decaying animal remains, they recycle nutrients back into the soil. They are used in forensic entomology to help determine time of death.
The parent beetles work together to create a nursery for their young in an underground chamber with a mammal or bird corpse. Then the female watches over the eggs and feeds the larvae with the partially digested carcass.
