The relationship of the insect is unclear as well as the in the Paleozoic Era Fossilized insects of enormous size has been found or the most of the insects are coevolved with flowering plants. Here we discuss about the insect so the insect are typically move about by walking as well as by flying or sometimes by swimming.
Synonyms of the Insect are Entognatha as well as Entomida or Kingdom is Animalia as well as Class is Insects or Phylum is Arthropoda. The main thing is that the word insect comes from the Latin word insectum or the meaning is "with a notched or divided body" as well as literally "cut into".
Here we discuss some types of the Insects like Coleoptera, Lepidoptera, Diptera, Hymenoptera, Hemiptera, Orthoptera, Trichoptera, Blattodea, Odonata, Neuroptera, Thysanoptera, Psocoptera, Phthiraptera, Plecoptera, Ephemeroptera, Phasmida, Mantodea, Siphonaptera, Dermaptera, Mecoptera, Strepsiptera, Zygentoma, Archaeognatha, Embioptera, Megaloptera, Raphidioptera, Zoraptera, Grylloblattodea, Mantophasmatodea all those is a type of the extant insect as well as we are also describe Estimates of total extant insect species for example Coleoptera-386,500, Lepidoptera-157,338, Diptera-155,477, Psocoptera-5,720, Phasmida-3,014, Siphonaptera-2,075, Mantophasmatodea-15 and so on insects are there.
Termites, ants as well as many bees and wasps are a familiar as well as social insects and also familiar species of eusocial animals or the all Social Animals are live together as well as live in the large well-organized colonies. Most of the insect are soft bodied as well as fragile and also almost defenseless compared to other and larger life forms or the some insects are move slowly as well as immature stages are small.
The Cladogram is living in the groups as well as they are live with number of species in each group or the Apterygota, Palaeoptera, and Exopterygota is possibly live in paraphyletic groups.
The evolutionary relationship of insects is unclear compare to other animals so we need to know about the evolution and is that the insects are grouped with millipedes and centipedes and probably based on convergent adaptations to terrestrialization and the insects are make the natural clade with the combination of Entognatha, Remipedia, and Cephalocarida and after that the insect make a single clade or that clade is related to crustaceans and myriapods.
Insects morphology like antenna, ocelli, compound eye, brain, anus, mid-gut (stomach), dorsal tube (Heart) Malpighian tubes, forewing, hindwing, trochanter, salivary gland, mouthparts, claws, tracheal tubes, femur, trochanter, dorsal blood vessel, ovary, oviduct, foregut (crop, gizzard), nerve chord (abdominal ganglia), hind-gut (intestine, rectum & anus) and so on.
