Aedes atropalpus
Aedes atropalpus, commonly known as the American rock pool mosquito, is a species of mosquito in the family Culicidae. It belongs to the subgenus Georgecraigius and was first described by American entomologist Daniel William Coquillett in 1902. Native to eastern North America, this mosquito has also been reported in parts of Europe, likely introduced through human activities such as the transport of used tires.
Description
Aedes atropalpus is a small to medium-sized mosquito characterized by a slender body, long legs, and a proboscis suited for blood-feeding. While specific physical traits may vary, it shares typical mosquito features such as dark coloration and scaled wings. Females exhibit autogeny, meaning they can lay their first batch of eggs without a blood meal, a distinctive adaptation among some mosquito species.Distribution and habitat
This species is primarily found in eastern North America, with a range extending from Canada to the southeastern United States. It has also been introduced to Europe, with sightings in countries such as Italy and France, likely due to the international trade of used tires carrying its eggs. Aedes atropalpus thrives in small, water-filled habitats, including natural rock pools along streams and rivers, as well as artificial containers like tires, buckets, and other debris. Its ability to exploit human-made environments has contributed to its spread.Life cycle and behavior
Aedes atropalpus undergoes complete metamorphosis, progressing through egg, larval, pupal, and adult stages. Females lay eggs in moist areas above the waterline of their breeding sites, and these eggs can survive desiccation, hatching when flooded. The larvae develop in water, feeding on organic debris, and adults emerge after a brief pupal stage.The species’ autogenous reproduction allows it to thrive in areas with limited host availability. Adults are active during the day and feed on the blood of humans and other mammals, making them a nuisance in areas near their breeding sites.
