Ochlerotatus (Aedes) triseriatus

Ochlerotatus triseriatus

Ochlerotatus triseriatus (Eastern Treehole Mosquito)  is widely distributed east of the Rocky Mountains and inhabits all of the Southeastern States. This common woods species is identified by the silvery-white scales on the sides of the thorax and unbanded legs and proboscis. Although breeding does occur to some extent in water barrels and other artificial water containers, primary breeding occurs in tree holes. Adult mosquitoes will not venture further than necessary from their larval sites. Oc. triseriatus survives the winter in the egg stage in regions of ice formation; eggs are laid under water or in areas where water will occur in early spring. This species is typically considered a troublesome biter in wooded areas and will readily attack humans.
