Dasycorixa hybrida is a Wisconsin Special Concern water boatman that has been found in pothole lake in Chippewa County. Water boatmen belong to the Corixidae family and most often occur in lakes, ponds, rivers, streams, and marshes. Like several aquatic insect families, water boatmen breath beneath the surface by clutching a bubble of air under their wings. Most species are collectors or gatherers and feed on small organisms found in sediment. Adults are 3-11mm long.
