Presence and abundance of Culex tarsalis along elevation-climate gradients
In 2006, we collected mosquitoes along two elevation-climate gradients in Larimer County: the Poudre River corridor and the Big Thompson River corridor

Two CDC light traps baited with dry ice (to produce carbon dioxide to attract mosquitoes) were used in each site Traps were placed in areas with cottonwood or willow along rivers or streams Sites were trapped every 2 weeks from June-September |

![]() All sites along the Poudre River corridor produced at least one Cx. tarsalis but the abundance was very low above 6,000 ft and the mosquitoes caught at these higher elevations appeared late in the season. |

Many mosquito species are common only at low elevations but others are adapted to the mountains
