Culex erraticus
Erratic Mosquito
Culex erraticus is a mosquito species in the family Culicidae, subgenus Melanoconion. It is a documented vector of eastern equine encephalitis virus (EEEV) and West Nile virus, with females exhibiting aggressive biting behavior toward birds, mammals, amphibians, and reptiles. The species shows distinctive seasonal host-shifting behavior, feeding primarily on ectothermic hosts during warmer months and shifting to endothermic hosts during cooler periods. It has been observed overwintering as adults in gopher tortoise burrows in Florida and in swamp habitats elsewhere.
