Aedes albopictus
, North American land favoring the environmental conditions of the Asian tiger mosquito was expected to more than triple in size in the coming 20 years, especially in urban areas. "Aedes albopictus" mosquitoes have been identified in 1,368 counties in 40 U.S states. A 2019 study in Nature Microbiology that modeled expansion of "Aedes albopictus" due to climate change, urbanization, and human movement found that the species would likely continue to spread throughout the coming decades.
