Common name : Water boatman
Scientific name : Sigara arguata
Family : Corixidae
Native to : New Zealand
Interesting fact : Unlike a backswimmer, water boatman is an aquatic insect that swims near the bottom of a stream or pond.
5-6 mm in length, the water boatman does not necessarily fly. However, some adults have wings and may use them to fly in case of overcrowding or the water-body drying up. Their diet is comprised of algae, and decaying plant and animal matter found at the bottom of the stream or pond. They are generally found in freshwater bodies. While foraging for food underwater, they use air which is held in a cavity under the wings.
