Vector Information

Found primarily east of the Great Plains, Culiseta melanura are common in diverse habitats from Florida north into New England and southern Canada. Cs. melanura has multiple generations per year in the southern part of its range (Horsfall 1955), but Mahmood and Crans (1998) suggest that the species has only two generations per year in the northeastern portion of its range due to cold temperatures. Adult females favor laying their eggs in habitats with acidic water and are normally captured near water with a pH of 5.0 or lower (Crans 2010). Females lay their eggs on the surface of water in underground crypts such as around the base of cypress, white cedar, or red maple trees or in rotted out stumps (Carpenter and LaCasse 1955). The breeding cycle (egg, larvae, pupae, adult) of Cs. melanura takes two or more weeks depending on temperature. Larvae hatched late in the season overwinter in water bodies and pupate the following spring. Appearance resembles that of Culex mosquitoes, with a white-scaled head, brown thorax, black abdomen with sporadic white or yellow scales, and a distinctively long, curved proboscis. Primarily aviphilic, Cs. melanura is responsible for maintaining the enzootic cycle of eastern equine encephalitis and also carry several other diseases. They are thought to feed almost exclusively on birds.

*Disease transmission varies locally. This map depicts where vectors can be found geographically and provides information about diseases these vectors might carry. Vectors might be present in a state or locality, however, and not be carriers of any particular disease. In addition, identified vectors may have a presence in a state, but may not be found throughout that state.
