Arizona's Uninvited Guest: The Mosquito that Won't Leave The discovery of a new mosquito species, Aedes amateuri, in Arizona has sparked interest among scientists.
This non native insect, previously known to Mexican entomologists, has made itself at home in the state's southeastern Sky Islands.
Arizona already boasts an impressive 40 plus species of mosquitoes, many of which thrive during the region's wettest months between March and October.
