Culex restuans is a species of mosquito known to occur in Canada, the United States, Mexico, Guatemala, Honduras, and the Bahamas.

[9] Without these distinctive white dots, this species looks very similar to another medically important Culex mosquito, Cx pipiens.

pipiens and restuans in reputable keys, and identified five characters that reliably distinguished these two species in their data set collected from Minnesota and Wisconsin.

[14] They go through four larval instars before pupating and then eclosing into adults; this process can take a minimum of 10 days in water with plenty of organic matter.

[15] These are significant in regards to vector dynamics because of their usual proximity to human habitat and their ability to assist in expansion of mosquito range.

restuans larvae remains largely unknown, but in the laboratory they are commonly fed on a diet that consists of ingredients like fish food, rabbit pellets, and liver powder.

[20] The Northeast Regional Center for Vector-Borne Disease reports widespread trends of low- and moderate-level insecticide resistance to methoprene in Culex spp.
