Insects (Insecta), are a class of invertebrate animals of the phylum
of arthropods, characterized by presenting a pair of antennae, three pairs of legs and two pairs of wings (which, however, may be reduced or missing). The science
that studies insects is called entomology. Its name comes from the latin insectum, tracing from the Greek ἔντομα, ' cut in the middle.
Insects comprise the Group of animals most diverse land, with approximately
1 million described species, 2 more that all other groups of animals together, and with estimates of up to 30 million species not described, thereby, potentially, would represent more than 90% of the
ways of life of the planet.3 other more recent studies reduce the number of insects discovered at between 6 million and 10 million.
Insects can be found in nearly all environments on the planet,
although only a small number of species has adapted to life in the oceans. There are approximately 5,000 species of Odonata (dragonflies, horses of the devil),
20,000 of Orthoptera (grasshoppers, crickets), 120,000 of Lepidoptera (butterflies and moths), Diptera (flies, mosquitoes) 120,000, 82,000 of Hemiptera (chinches, aphids, cicadas), 350,000 of
Coleoptera (beetles, ladybirds), and 110,000 species of Hymenoptera (bees, wasps, ants).
Insects do not only present a great diversity but are also incredibly
abundant. It is estimated that there are 200 million insects for every human being. Some nests contain more than 20 million
individuals. There are an estimated 1015 ants living on Earth. In the Amazon jungle is estimated that individuals there are
over 60,000 species and 3.2 x 108 per hectare.
Arthropods land such as centipedes, millipedes, scorpions and spiders are
often confused with insects since they have similar body structures, but they are easily distinguishable since insects have three pairs of legs while scorpions and spiders have four pairs and lack
antennae, and centipedes and millipedes have many pairs of legs.
