Pteronarcyidae
The Pteronarcyidae, also known as giant stoneflies or salmonflies, are a family of the order Plecoptera. Natural history Two genera of Pteronarcyidae are found; ''Pteronarcys'' is found in all of North America, while ''Pteronarcella'' is found only in the west. The two genera comprise 10 distinct species, two of which are ''Pteronarcella''. Lifespans range from one to four years. The name "salmonflies" comes from their role in the diets of salmon, and they play an important role in fly fishing. Adults emerge from April to June. The giant stoneflies are very sensitive to stress. Habit and habitat They live in a lotic-erosional habitat. Larvae of giant stoneflies live in cool streams of small to medium size, in leaf and woody debris packs. They prefer swift riffle A riffle is a shallow landform in a flowing channel. Colloquially, it is a shallow place in a river where water flows quickly past rocks. However, in geology a riffle has specific characteristics. Topographi ...

Plecoptera
Plecoptera is an order of insects, commonly known as stoneflies. Some 3,500 species are described worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger. Their modern diversity, however, apparently is of Mesozoic origin. Plecoptera are found in both the Southern and Northern Hemispheres, and the populations are quite distinct, although the evolutionary evidence suggests species may have crossed the equator on a number of occasions before once again becoming geographically isolated. All species of Plecoptera are intolerant of water pollution, and their presence in a stream or still water is usually an indicator of good or excellent water quality. Description and ecology Stoneflies have a generaliz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
