Perlodidae
The Perlodidae, also known as the perlodid stoneflies, stripetails, or springflies, are a family of stoneflies. Natural history The family Perlodidae is composed of at least 50 genera and over 350 species, with the fossil records extending at least from the Triassic. The majority of perlodid stoneflies are univoltine - one generation occurs per year. Usually, adults emerge from April to June. Many species have an egg diapause during the warmer months; this allows them to inhabit otherwise unfriendly environments like temporary seeps or streams. Larvae have flattened bodies, often with patterns on their heads and thoraces, long tails, and divergent hind wing pads. Unlike the similar common stoneflies, perlodid larvae do not have branching gills on their thoraces. The perlodids are found throughout North America. Habit and habitat The Perlodidae are generally lotic and lentic erosional. These habitats are flowing streams or pools that contain sediments, vascular plants, and detri ...

Stoneflies
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.
