Ranatra
Ranatra is a genus of slender predatory insects of the family Nepidae, known as Water mantis, water scorpions or water stick-insects. 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). 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.

Ranatra es un género de hemípteros heterópteros de la familia Nepidae, conocidos como insectos palo acuáticos. Son predadores y usan sus fuertes patas delanteras para capturar las presas. Son generalmente delgados, respiran a través de un par de grandes pipas respiratorias extendidas en sus colas. Comen renacuajos, pequeños peces, otros insectos, que matan con su pico, inyectando una saliva que tanto seda como comienza a digerir la presa. Invernan como adultos, la hembra pone huevos en primavera, en la vegetación; llevándoles típicamente dos a cuatro semanas en eclosionar, y los recién nacidos tardan cerca de dos meses en madurar.

Ranatra is a genus of slender predatory insects of the family Nepidae, known as Water mantis, water scorpions or water stick-insects. 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). 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. Since Ranatra belongs to the family Nepidae which in turn belongs to the order Hemiptera, Ranatra 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. Exceptionally they have been recorded from hypersaline lakes and brackish lagoons.
