	Peltoperlidae The Peltoperlidae, also known as roach-like stoneflies or roachflies, are a family of stoneflies. The family Peltoperlidae comprises 11 genera and 46 known species. Species are semivoltine, meaning their lifecycles last one to two years. Adults of the family usually emerge in late spring or early summer, April through June. Larvae are flattened and brown in color, and they are roach-like in appearance because of the expanded thoracic plates covering the bases of their legs, heads, and abdomens. Tapering gills occur on the thorax at the bases of the legs. These tracheal gills are multifunctional and key to many biological processes. No dense tufts or branching gills are found on their thoraces or abdomens, unlike other Plecoptera families. The larvae also possess broad, chisel-like mandibles. Adults have two ocelli in addition to their two compound eyes. Male epiprocts are sclerotized and rod-like in shape, and both sexes lack cross-veins in the anal lobe of the forewings. P ...

picture info	Plecoptera Plecoptera is an order (biology), 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 hemisphere, 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 the presence of their nymph (biology), nymphs in a stream or still water is usually an indicator of good or excellent water ...
