The Perlodidae, also known as the perlodid stoneflies, stripetails, or springflies, are a family of stoneflies.
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.
The Perlodidae are generally lotic and lentic erosional. These habitats are flowing streams or pools that contain sediments, vascular plants, and detritus. They are most often found in cool, clear streams with rocky bottoms. They are found under rocks and in coarse particulate organic matter where many prey are to be found. The larvae are generally considered to be clingers as can be seen by their wide stance for gripping substrates.
The perlodid larvae are mostly predators that engulf their prey, although a few species are scrapers and collector-gatherers. They will eat a variety of small invertebrates, but they are also known to eat plant matter, especially when young.
Selected genera in the two subfamilies include: [1] [2]
Taeniopterygidae are a family of stone flies with about 110 described extant species. They are commonly called willowflies or winter stoneflies and have a holarctic distribution. Adults are usually smaller than 15 mm.
The Peltoperlidae, also known as roach-like stoneflies or roachflies, are a family of stoneflies.
The Perlidae are a family of stoneflies, with more than 50 genera and 1,100 described species. The majority of the Perlidae are found in eastern North America, but they occur worldwide except for Antarctica and parts of Africa. Their lifecycles range between one and three years. They adults emerge in the summer; they are very active and known to be attracted to light sources. They are usually very sensitive to changes in environment.
The Capniidae, the small winter stoneflies, are a family of insects in the stonefly order (Plecoptera). It constitutes one of the largest stonefly families, containing some 300 species distributed throughout the holarctic. Their closest relatives are the rolled-winged stoneflies (Leuctridae).
Arctoperlaria is a suborder of stoneflies, with a World-wide distribution. The Plecoptera Species File divides this suborder as follows:
Chloroperlidae are a family of stoneflies, commonly known as green stoneflies, with more than 200 species and 22 genera. They appear green to yellow in colour, and are popularly used among fisherman as bait for trout fishing. Green stoneflies live in the benthic zone of the cold streams and rivers of five continents and four zoogeographical regions, emerging from the water to live in the riparian zone as adults. They are sensitive to pollutants, making them an indicator species for determining the quality of water bodies. Chloroperlidae are hemimetabolous, having no pupal stage, but instead hatch from eggs as nymphs and mature directly into adults. They are omnivorous, feeding on small organisms and plant particles, and become more carnivorous as they mature. The classification of Chloroperlidae is contested, with some believing that they should be considered as members of different orders, as opposed to the order Plecoptera that they currently belong to.
