Brazil's Fauna

Insects from Brazil (class Insecta)



        The insects are from the Class Insecta, Phylum Arthropoda, Kingdom Animalia, and there are about 1 million species, what makes it the most numerous class. They occur in almost all of the Earth's environments.

        One of the main imediate identification of external characteristics of the insects is the existence of distinct head, chest and abdomen and 3 couples of articulated legs in all of them.  

        By their way of life insects can be divided into solitaries and social. Among social insects, distinction for ants and bees, that are well known.

        The Science that studies insects is called ENTOMOLOGY.

        In relation to men, many insects are useful (ex.: bees). On the other hand they can bring prejudice (ex.: mosquitoes).

        Besides insects being in a great number, they are practically the firt victims of environmental degradation, when there is a deforestment and mainly with insecticides aplication.



        As all scientific systematic classification, in the insects there are also differences.

        We have taken as basis Costa Lima's classification, used by many authors and quoted by Carrara, also using another sources, also increasing the number of families and species.

        As in all systematic scientific classification, in the insect class there are also some differences.
