Invasive mosquito species discovered in Florida raises disease concerns.

A new species of mosquito, Culex lactator, has been discovered in Florida and has made a permanent home in at least three counties. Researchers are concerned about the potential disease risk to humans as there hasn't been enough research on the species. Due to its tropical climate, Florida faces challenges from a variety of mosquito-transmitted diseases like West Nile virus, dengue, and chikungunya, which are spread by mosquitoes. Climate change could increase the chances that tropical mosquito species will become established once they arrive in Florida.
