Larvae of various species develop in standing water of ponds and marshes, snowmelt pools, empty barrels, used tires, bird baths, tin cans etc. (specific larval habitat varies according to species)
adults found year round, even in northern latitudes (BG data)
Cx. nigripalpus, Cx. pipiens, Cx. tarsalis all shift (at least regionally) from feeding primarily on birds in spring to an increasing fraction from mammals in later summer (3)(4)
