Adults of Culex territans are small with a light brown thorax and dark brown abdomen. The underside of the abdomen is entirely white. Females feed almost exclusively of frogs but occasionally will take a meal from lizards, birds and mammals. They are not important for the transmission of any human pathogens. Larvae are found in a wide variety of natural and man-made habitats including ponds, marshes, vernal pools, tree holes, ditches and tires.
