Members of the genus Ranatra, the most widespread and species-rich genus, are sometimes called needle bugs or water stick insects as they are slenderer than Nepa. [ 3 ] While water scorpions do not sting with their tail (it is used for breathing), [ 4 ] they do have a painful bite (strictly speaking a sting by their pointed proboscis ), but ...
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.
It lives in ponds, small rivers, and stagnant water, and feeds upon aquatic animals, especially insects. Respiration in the adult is effected by means of the caudal process, which consists of a pair of half-tubes capable of being locked together to form a siphon by means of which air is conducted to the tracheae at the apex of the abdomen when ...

Laccotrephes tristis is a species of water scorpion also commonly known as a toe-biter, that occurs Australia-wide and is part of the family Nepidae. [2] [3] They are an aquatic predatory insect that breath air. [2] Australian water scorpions inhabit shallow stagnant water, part of freshwater creeks, waterholes and gorges. [2] [4]
(They can be found around the world, and there are more than 50 different species that bite humans.) They are arachnids, not insects, and are more closely related to spiders and ticks.
Ranatra is a genus of slender predatory insects of the family Nepidae, known as water scorpions or water stick-insects. [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]).
