Infrequent. (Connelly, 2010)

Distribution: Darsie and Ward (2005): Palearctic; Eastern, Central, Northwest United States, Canada. GSMNP: Tennessee. Egg: Rafts of 100 or more eggs are laid on the water surface. Culex territans can lay eggs on moist soil where rising water will float the egg raft into suitable aquatic environment. Larva and pupa: Permanent and semi-permanent pools in streams, ponds, and swamps. Prefer clear water with emergent vegetation. Sometimes found in rock pools associated with Aedes atropalpus. Adult: Prefer to feed on cold-blooded animals, especially frogs. Overwinter as females in cool climates. Note: Bartlett-Healy et al. (2008, 2009) found that Culex territans adult females were attracted to frog calls of Pseudacris crucifer (Wied-Neuwied) (spring peepers), Hyla versicolor LeConte (northern gray tree frog), Bufo americanus Holbrook (American toad), and Rana clamitans Latrielle, (the green frog), and that the larvae were associated both temporally and spatially with R. clamitans, in New Jersey.
