The lesser waterboatman or lesser water boatman is a water-dwelling insect of the order Hemiptera.
Corixidae is a family of aquatic insects in the order Hemiptera. They are found worldwide in virtually any freshwater habitat and a few species live in saline water. There are about 500 known species worldwide, in 33 genera, including the genus Sigara.
Notonectidae is a cosmopolitan family of aquatic insects in the order Hemiptera, commonly called backswimmers because they swim upside down. They are all predators and typically range from 0.5 to 1.5 cm (0.2–0.6 in) in length. They are similar in appearance to Corixidae, but can be separated by differences in their dorsal-ventral coloration, front legs, and predatory behavior. Their dorsum is convex, lightly colored without cross striations. Their front tarsi are not scoop-shaped and their hind legs are fringed for swimming. There are about 350 species in two subfamilies: Notonectinae with seven genera, and Anisopinae with four genera. Members in the former subfamily are often larger than those in the latter.
Nepomorpha is an infraorder of insects in the "true bug" order (Hemiptera). They belong to the "typical" bugs of the suborder Heteroptera. Due to their aquatic habits, these animals are known as true water bugs. They occur all over the world outside the polar regions, with about 2,000 species altogether. The Nepomorpha can be distinguished from related Heteroptera by their missing or vestigial ocelli. Also, as referred to by the obsolete name Cryptocerata, their antennae are reduced, with weak muscles, and usually carried tucked against the head.
Notonecta glauca is a species of aquatic insect, and a type of backswimmer. This species is found in large parts of Europe, North Africa, and east through Asia to Siberia and China. In much of its range it is the most common backswimmer species. It is also the most widespread and abundant of the four British backswimmers. Notonecta glauca are Hemiptera predators, that are approximately 13–16 mm in length. Females have a larger body size compared to males. These water insects swim and rest on their back and are found under the water surface. Notonecta glauca supports itself under the water surface by using their front legs and mid legs and the back end of its abdomen and rest them on the water surface; They are able to stay under the water surface by water tension, also known as the air-water interface. They use the hind legs as oars; these legs are fringed with hair and, when at rest, are extended laterally like a pair of sculls in a boat. Notonecta glauca will either wait for its prey to pass by or will swim and actively hunt its prey. When the weather is warm, usually in the late summer and autumn, they will fly between ponds. Notonecta glauca reproduce in the spring.
Chironomus plumosus, also known as the buzzer midge, is a species of nonbiting midge (Chironomidae) that occurs throughout areas in the Northern Hemisphere.
Water boatman as a type of aquatic insect can mean:
In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". He described the Insecta as:
A very numerous and various class consisting of small animals, breathing through lateral spiracles, armed on all sides with a bony skin, or covered with hair; furnished with many feet, and moveable antennae, which project from the head, and are the probable instruments of sensation.
Notonecta maculata is a backswimmer of the family Notonectidae, found in Europe, including the United Kingdom.
Notonecta undulata, also known by the common name grousewinged backswimmer, are from the family Notonectidae and the insect suborder Heteroptera. They are a type of hemipteran or true bug. These aquatic insects typically spend their time at the water's surface, using their abdomen and legs to cling to the underside of the surface tension. The Grousewinged backswimmer can be found in both lotic and lentic environments; however, they typically prefer small ponds and lakes where the water is slow-moving with less current. They swim upside down looking for prey. Once they stop swimming they float back up to the surface. These insects can be distinguished from water boatman or Corixidae by their segmented beak and front legs. Water boatman have highly modified front legs whereas backswimmers do not. Backswimmers are distributed across a broad range throughout North America. However, the species Notonecta undulata has only been documented and studied in southern Manitoba, Saskatchewan, Alberta and the western United States. N. undulata differs from other backswimmers by their antennae and size. They are approximately 10–12 mm long, and their antennae are 4 segmented
Notonecta irrorata is a species of backswimmer native to North America first described by Philip Reese Uhler in 1879. Presence of N. irrorata in ponds is known to repel the oviposition of Culex mosquitoes.
Notonecta spinosa is a species of backswimmer in the family Notonectidae. It is found in North America.
Notonecta kirbyi, or Kirby's backswimmer, is a species of backswimmer in the family Notonectidae. It is found in North America.
Notonecta unifasciata is a species of backswimmer in the family Notonectidae. It is found in Central America, North America, and South America.
Notonecta lunata is a species of backswimmer in the family Notonectidae. It is found in North America.
Notonecta lobata is a species of backswimmer in the family Notonectidae. It is found in Central America and North America.
Notonecta borealis is a species of backswimmer in the family Notonectidae. It is found in North America.
Notonecta indica is a species of backswimmer in the family Notonectidae. It is found in the Caribbean Sea, Central America, North America, Oceania, and South America.
Notonecta insulata is a species of backswimmer in the family Notonectidae. It is found in North America.
Notonecta uhleri is a species of backswimmer in the family Notonectidae. It is found in North America.
