Which two species have a flight variant less than 10-20 miles?

• A. Aedes vexans and Ochlerotatus
• B. Aedes aegypti and Aedes albopictus
• C. Anopheles gambiae and Culex quinquefasciatus
• D. Aedes aegypti and Anopheles gambiae

Answer: (A)

Understanding how far mosquitoes typically fly helps explain where they’re likely to spread or stay contained. Some species are strong fliers and can move across neighborhoods or even larger areas, while others tend to stay close to where they breed. Aedes vexans and the Ochlerotatus group are examples of the latter. They generally remain near their breeding habitats and don’t routinely travel many miles, often staying within a short radius—well under the 10–20 miles threshold. This makes them the best fit for a question about short-range flight. Other options involve species that can disperse more widely under normal conditions, so their typical flight range is not limited to such a small distance.
