Which of the following time periods describes 'crepuscular' activity?

'Crepuscular' activity refers specifically to the behavior of certain organisms that are most active during the twilight hours of dawn and dusk. This term is derived from the Latin word 'crepusculum', meaning 'twilight'. Many species, including certain types of mosquitoes, tend to feed or engage in other activities during these times to avoid the harsher sunlight of midday and to take advantage of the low light for camouflage and predator avoidance.

Understanding crepuscular behavior is crucial for mosquito control because it helps in determining the most effective times for surveillance and treatment. Being aware that these insects are active at these specific times allows applicators to time their control efforts appropriately for maximum effectiveness. This knowledge can contribute significantly to managing mosquito populations and reducing the risk of mosquito-borne diseases.
