[1] There are more than 140 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]).
Nepa is a genus belonging to the family Nepidae, known as water scorpions.Species are found in freshwater habitats in the Northern Hemisphere. [2] [3] [4]They are oval-bodied, aquatic insects with raptorial front legs.
