Are Northern Fence Lizards diurnal or nocturnal?

Northern Fence Lizards are diurnal, meaning they are active during the day and rest at night. This behavior is typical for many lizard species, as daytime activity allows them to bask in the sun to regulate their body temperature and engage in foraging for food, as they primarily feed on insects and other small invertebrates. Being diurnal also allows them to avoid some of their natural predators that may be more active during the nighttime hours.

The other choices refer to different patterns of activity; nocturnal species are active at night, while crepuscular species are active during the twilight hours of dawn and dusk. Ambivalent refers to an organism that does not have a clearly defined pattern of activity. In this case, the distinct diurnal behavior of Northern Fence Lizards makes the correct answer clear.
