nocturnal behavior
Darkness-driven actions pattern
Nocturnal behavior refers to activity that occurs during the night rather than the day.
The term appears most often in biology, describing animals that sleep by day and hunt, forage, or mate after dark: Owls exhibit nocturnal behavior, hunting rodents under cover of darkness.
Applied to humans, it often carries a hint of irregularity or unhealthiness: His nocturnal behavior worried his parents.
