The internal anatomy of an insect the internal organs of insects, like those of other animals, are grouped into various systems but these systems differ in many ways from those of other animals. The amazing success of the insects must in part lie with the incredible mixture of flexibility and strength of the integument (that is the part of an insect that makes up the hard exoskeleton) that allows insects their freedom of movement without loss of defence and protection. The anatomy of ants usually serve as the example insect when talking about their body construction their three body parts (four or five when counting the petiolus and postpetiolus) together with their six legs forms a clear and symbolic icon of the insect world. Insects can be divided into two groups historically treated as subclasses: wingless insects, known as apterygota, and winged insects, known as pterygota the apterygota consist of the primitively wingless order of the silverfish (zygentoma) the respiratory system of insects constrains their size, however the high oxygen in the atmosphere.
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 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. Insect morphology is the study and description of the physical form of insects the terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Page details a basic guide to insect anatomy though very understandable - anatomy which is one of the better ways to understanding them in whole more about insects: nature's workhorse: anatomy of the honey bee more, or else the insect will not grow into it's new larger size some insects have been know to molt over 20 times in their.
Classification of arthropods the insecta (insects) are a class of the large animal phylum called arthropoda subclasses & features 1 thysanura: bristletails: apterygota these are wingless insects and their body structure suggests that they have never had wings during their evolutionary history young stages resemble the adults - little. In a volume as jewel-like as its subject, the anatomy of insects & spiders presents page after page of select engravings, woodcuts, and drawings from the victorian era, the golden age of insect illustration meticulously rendered, they are paired with observations from early naturalists.

Most insects possess one pair of compound eyes and sometimes some simple eyes called ocelli mouthparts there is a big variety in types of mouthparts biting, sucking, stinging, licking, etc. Mammals that give birth to their young ones directly belong to the subclass eutheria the young ones form as an embryo in the mother stomach and grow there for a certain period of time this subclass consists of 19 orders.
Subclass apterygota (=ametabola) primitively wingless insects, without metamorphosis head is prognathous abdominal appendages may be present ectognathous mouthparts, with mandibles attached at one point there is no metamorphosis as nymphs are similar to adults the subclass has 4 orders 1orderprotura (telson tails) 2. Insects can be divided into two groups historically treated as subclasses: wingless insects, known as apterygota, and winged insects, known as pterygota the apterygota consist of the primitively wingless order of the silverfish (zygentoma.
The feet-tips of insects will usually contain sticky pads, hooks or suckers of some type which allow the inset to cling to various types of surfaces or to clasp on to it's prey the abdomen makes up the last, and probably the most recognizable, part of the insect. Each of the insect orders are listed below and, by following the links, information on each order is provided (main characteristics, life cycle and other interesting facts) along with links to other web sites containing further information:.
