Observations on a Mosquito Flight in Salt Lake City

In a survey of the mosquitoes of Salt Lake City carried on since 1929, a number of mosquito flights have been observed and recorded. These flights have occured principally in three species of mosquitoes common to region,- Aedes campestris Dyar and Knab Aedes vexans (Meigen) and Aedes dorsalis (Meigen). These mosquitoes appear in large broods when conditions are favorable and their flights have been definitely traced for several miles on different occasions. Aedes campestris appear in greater numbers during May and June and some of this species have been taken during the season ten miles from their nearest breeding area. Aedes vexans are more numerous during June, July and August. The flight of this mosquito has been traced from five to eight miles from its nearest breeding water. Undoubtedly many of the adults taken flew a greater distance than the maximum flight we were able to determine.
