Which term describes animals active at dawn and dusk?

Explanation:
Crepuscular describes animals that are most active during the dim light of dawn and dusk. This timing matches the question exactly, since it highlights activity in the twilight hours. The word comes from crepusculum, meaning twilight, which captures that specific window of time. Animals like deer, rabbits, and many insects are crepuscular, using the low light to forage while avoiding some daytime heat or predators. In contrast, diurnal species are active during the day, and nocturnal ones at night, while twilight itself is a time of day rather than a behavior pattern.
