What is a notable flight distance capability of Cx. tarsalis?

• A. They can fly up to 1 mile
• B. They can fly up to 15 miles
• C. They never fly beyond a few hundred feet
• D. They only fly within a small yard

Answer: (B)

Long-range dispersal is the key idea here: Culex tarsalis is a relatively strong flyer among mosquitoes, capable of moving across substantial distances to find hosts and breeding sites. In field studies, mosquitoes of this species have shown the ability to travel tens of kilometers under certain conditions, which is commonly summarized as reaching about 15 miles. This level of flight makes them capable of spreading to new areas even when local hosts or habitats aren’t immediately nearby, and it has important implications for disease transmission and control efforts. The other options underestimate what this species can do. Some mosquitoes tend to stay close to where they emerge, but Cx. tarsalis has demonstrated dispersal well beyond a small yard or a few hundred feet, and its typical range can exceed a mile, with the upper end described around 15 miles in capable conditions.
