Nocturnal Creatures: Adults are most active at night and are attracted to lights.
Harmless to Humans: Stag beetles cannot sting and are generally harmless. They are protected in many European countries.
Indicator Species: They are considered indicator species for healthy woodland habitats with plenty of dead wood.
