The female mosquito needs a blood meal in order to produce eggs. Blood meal hosts range from reptiles, amphibians, mammals, birds, to humans. All mosquito species are potential vectors of organisms that can cause disease to pets, domestic animals, wildlife, or humans. They occur in snow melt pools and usually do not fly far from their larval sources. They are day or night biters.
Immature stages develop in any standing freshwater source.
Females are night feeders mostly on birds, but will switch to mammals including man. These mosquitoes breed in ponds, basins, and artificial containers. Females actively feed at dawn and dusk mainly on large domestic animals and man. Females do not fly far from larval sources, and are vicious day biters of large mammals including man. Encephalitis is a flu-like illness caused by a virus.
