Which of the following is a natural enemy of mosquitoes?

Dragonflies are a natural enemy of mosquitoes primarily because they are predatory insects that feed on them during both their larval and adult stages. As larvae, dragonflies are often found in aquatic environments where they can consume mosquito larvae. In their adult form, dragonflies are agile flyers capable of catching mosquitoes mid-air. Their role as predators helps to regulate mosquito populations, making them an important component in the ecosystem and a beneficial factor in mosquito management strategies.

Both butterflies and bees, while beneficial pollinators in their respective environments, do not prey on mosquitoes, and ladybugs typically feed on aphids rather than mosquitoes. This distinction highlights the specific role that dragonflies play in controlling mosquito populations.
