New Mosquito Species Detected in Arizona Could Reach New Mexico

UF researchers confirmed the first U.S. sighting of Aedes amateuri in Arizona's Madrean Sky Islands (Santa Rita and Dragoon Mountains) and possibly near the New Mexico border; the species can bite humans but is not currently known to spread diseases. The discovery underscores ongoing surveillance for invasive mosquitoes as climate change and global connectivity raise detections, even as public-health risk remains uncertain.
