Ochlerotatus (Aedes) dorsalis
Ochlerotatus dorsalis is found abundantly in western South Dakota along with Ae. vexans. It can be differentiated from Ae. vexans by the yellowish-white scales covering their body. These mosquitoes are known for their incredible migration distances of 20-30 miles. This ferocious biter mainly feeds on humans or domestic animals, but will also feed on sizable birds when necessary. Most of the Ochlerotatus dorsalis' biting occurs on muggy days, but they will also bite during the night-time.
