![]() In places such as the desert, animals may pick times to move or hunt when temperatures are too high or are not too low. Since most animals hunt during the day or night, twilight hours are less crowded, allowing animals to avoid competition with similar species. Another idea has to do with food availability and competition. The dim light of dawn and dusk can provide cover for both predators to hunt their prey or prey animals to hide from predators. How could an animal or plant benefit from being crepuscular? Some scientists think that it could be to do with the amount of light. Plants can be crepuscular as well! Morning glory flowers are matutinal, opening in the early morning, while evening primrose flowers are vespertine, opening at dusk. Vespertine animals are those which are active at dusk, such as flies, moths, and some bats and owls. Matutinal animals are those which are active at dawn, such as some species of honey bees. Crepuscular animals can be further divided into two subgroups: matutinal and vespertine. Animals in this group will sleep at night and lie low during the day. But what about those of you who are awake between the hours of daylight and darkness? Well, luckily, there is a term for that too! Beings that are active during these twilight hours are called crepuscular!Ĭrepuscular animals are active at dawn and dusk, just as most of us humans are pressing snooze on our alarm clocks or winding down for the night. However, if you are awake at night and see yourself as a night owl, then you could be called nocturnal, someone who is active at night. When you think and look back at them how would you describe yourself? Do you consider yourself an early bird, a night owl, or something in between? If you consider yourself an early bird you might be called diurnal, someone who is active during the day. Think about your general sleeping habits.
