Geographic distribution

Culex species mosquitoes are widely distributed in the United States, including throughout Indiana. The Culex species mosquito of greatest public health importance in Indiana is the northern house mosquito, Culex pipiens.

Life cycle

The mosquito life cycle consists of four stages (egg, larva, pupa, and adult). The life cycle usually takes 2–4 weeks to complete, but it can be completed in less than one week during the heat of summer. Culex species are most active at dusk and dawn during the mosquito season (in Indiana, this is usually from May to October). Only female mosquitoes bite animals and people. Culex species mosquitoes prefer to lay their eggs in natural or artificial bodies of standing or stagnant water.
