Habitat Larvae of this large, bloodsucking midge were found in vegetated salt flats near Valdez, Alaska, in soil covered by 80 - 90 % of all high tides and inundated by an average of 18 inches (45 cm) of water (maximum 7 ft. of 2.1 m) for 6 or more hours a day. Some breeding occured also in the tidal overflow zones of snow-fed streams entering the sea. [details]
