Nepidae
Nepidae is a family of exclusively aquatic Heteropteran insects in the order Hemiptera. They are commonly called water scorpions for their superficial resemblance to scorpions, due to their raptorial forelegs and the presence of a long slender process at the posterior end of the abdomen, resembling a tail. There are 14 genera in the family, in two subfamilies, Nepinae and Ranatrinae. 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''. While water scorpions do not sting with their tail, they do have a painful bite (strictly speaking a sting by their pointed proboscis), but this is much less harmful to humans than a true scorpion's sting. Range and habitat Nepidae are found on all continents except Antarctica. They mostly inhabit stagnant or slow-moving freshwater habitats like ponds, marshes, canals and streams. Exceptionally they have also been recorded from hyp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ranatra Chinensis
''Ranatra'' is a genus of slender predatory insects of the family Nepidae, known as water scorpions or water stick-insects. 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 1972Lansbury I (1972) A review of the Oriental species of ''Ranatra'' Fabricius (Hemiptera-Heteroptera: Nepidae). ''Transactions of the Royal Entomological Society of London'', vol. 124, no. 3. 287-341.). 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 ''Ranatra linearis, R. linearis''. Since ''Ranatra'' belongs to the family Nepidae which in turn belongs to the order Hemiptera, ranatrids are considered "true bugs".

Nepa (insect)
''Nepa'' is a genus belonging to the family Nepidae, known as water scorpions. There are six species found in freshwater habitats in the Northern Hemisphere. They are oval-bodied, aquatic insects with raptorial front legs. Like other members of the Nepidae, they have a pair of nonretractable cerci-like breathing tubes on the terminal abdominal segment, a characteristic which readily distinguishes them from the Belostomatidae. Their primary staples are other insects and small aquatic vertebrates. They can inflict a painful bite when handled. Etymology 'Nepa' is a classical Latin word for a 'scorpion' or ' crab'. Species The following species are included in ''Nepa'': * '' Nepa anophthalma'' Decu et al., 1994 (see Movile Cave) * '' Nepa apiculata'' Uhler, 1862 * ''Nepa cinerea'' Linnaeus, 1758 - type species * '' Nepa dollfusi'' Esaki, 1928 * '' Nepa grandis'' Linnæus, 1758 * '' Nepa hoffmanni'' Esaki, 1925 * '' Nepa monteilsensis'' Nel, 1988 * '' Nepa plana'' Sulzer, 1776 ...

Ranatra Linearis
''Ranatra linearis'' is a species of aquatic bug in the Nepidae family. It is native to Eurasia and North Africa, and primarily found near aquatic plants in ponds, marshes and other freshwater habitats, but has exceptionally been recorded from hypersaline lakes and brackish Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuari ... lagoons. Description The body of these brown insects is typically long. Their breathing tube tail is usually about as long as the body of the insect. They are swimming insects, and the adults can fly.

Laccotrephes Cf Brachialis, Pretoria, J
''Laccotrephes'' is a genus of water scorpion belonging to the family Nepidae. They are carnivorous insects that hunt near the water surface. They are not aggressive, but may inflict a painful bite if not handled carefully, which may cause a local reaction. There are about 60 species found in shallow stagnant or slow-moving waters in warm parts of Africa, Asia and Australia. Anatomy 300px, ''Laccotrephes'' species in South Africa They are dark brown to rufous brown, elongate and flattened, aquatic insects with hooked raptorial forelegs and a long, thin tube (or siphon) protruding from the tip of the abdomen. The respiratory siphon consists of two filaments which are extensions of the eighth abdominal tergum. These in unison form an air duct which takes in air from above the water surface (similar to a snorkel). Air is fed via the tracheal system and spiracles on the dorsum of the first abdominal segment to an air store under the elytra. Populations The genus contains two distin ...

''Cercotmetus'' is a genus of water bugs in the subfamily Ranatrinae ("water stick-insects"). The recorded distribution of this genus is from is from mainland Asia to New Guinea and northern Australia. Description ''Cercotmetus'' species are similar to the related genus ''Ranatra'', but have distinctly shorter respiratory siphons (posterior breathing tubes, which are ¼ or less of the body length) and the front femur is shorter than length of the pronotum.

Nepa Cinerea
''Nepa cinerea'' is a species of water scorpion (Nepidae), found in most of Europe, including the British Isles, as well as North Africa and southern and northern Asia. Habitat and Biology 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 the tip of the tube is thrust above the surface of the water. In immature forms, the siphon is undeveloped and breathing takes place through six pairs of abdominal spiracle Spiracle or spiraculum may refer to: * Spiracle (arthropods), opening in the exoskeletons of some arthropods * Spiracle (vertebrates), openings on the surface of some vertebrates * Spiraculum, a genus of land snails in family Cyclophoridae Cycl ...s.

Hemiptera
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as Ant, ants, Bee, bees, Beetle, beetles, or Butterfly, butterflies.
