What period of time are most species of mosquitoes actively looking for a blood feeding?

• A. Sunset and midnight, with a second feeding period around sunrise. Some mosquitoes, including some Aedes species, prefer to feed during the daytime
• B. Dawn and early morning
• C. Midday only
• D. Night only

Answer: (A)

Most mosquitoes seek hosts during times when light is low and humidity is often higher, which happens around dusk and into the night. This crepuscular pattern means a main feeding window at sunset with activity extending through midnight, plus a secondary push around sunrise. It’s also important to note that some species, especially Aedes, will bite during the daytime as well. So the option that describes feeding activity at sunset and midnight, with a second period near sunrise, best matches how many species behave in the wild. The other timeframes don’t capture this common pattern across the majority of species, though there are exceptions.
