Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 general ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
