|Culex restuans |
Larvae: found in temporary water bodies and containers. Adults are found in a variety of habitats.
Early spring to fall, peaking in the early summer.
Adult: Abdominal tergites with a basal band of pale, silvery scales; scutum usually with a pair of pale spots located centrally; tarsomeres and proboscis uniformly dark-scaled. Can be quite difficult to separate from Culex pipiens, which occurs in Canada, but not Alberta. Larva: antenna tapering uniformly from base to apex, lacking abrupt constriction.
Females overwinter in caves and basements, emerging relatively early in the spring. Eggs are laid in rafts of a few hundred in a variety of containers, temporary and permanent/semipermanent ponds. Larvae develop relatively early, being somewhat more cold tolerant than other Culex. Adults emerge in the early summer and females take a blood meal (usually from a bird), preferring to feed in the shade or at dusk.
This species is not of conservation importance, but may vector some encephalitis diseases.
Females prefer to feed on birds, but will feed on mammals, including man. Larvae are detritivores.
Found in south and central Alberta (south of Edmonton). In North America, it is found east of the Rockies from central Alberta and across central Canada, south to Mexico and Florida. Unrecorded from Newfoundland and the territories.
