Ranatra is a genus of slender predatory insects of the family Nepidae, known as water scorpions or water stick-insects.[1] There are around 100 Ranatra species found in freshwater habitats around the world, both in warm and temperate regions, with the highest diversity in South America (almost 50 species) and Asia (about 30 species, reviewed in 1972[2]). Fewer are found elsewhere, but include several African, some in North America, three from Australia and three from the Palearctic, notably the relatively well-known European R. linearis.[3] Since Ranatra belongs to the family Nepidae which in turn belongs to the order Hemiptera, ranatrids are considered "true bugs".
These brown insects are primarily found in stagnant or slow-moving water like ponds, marshes and canals, but can also be seen in streams.[3] Exceptionally they have been recorded from hypersaline lakes and brackish lagoons.[4]
