Taxonomy, known in English as taxonomy, is derived from the ancient Greek τάξιςνομία. τάξις (taxis) means "arrangement"; νομία(-nomia) means "method". In biology, taxonomy is the study of the method and practice of grouping and naming organisms with common characteristics on the basis of scientific observation, research and description of the characteristics of various organisms. Insect taxonomy (insect taxonomy) insect taxonomy studies the identification of insects and their pedigree relationships, involving the identification, naming, classification, kinship between various orders and evolutionary relationships with other biological groups.
Overview of the suborder Insects:

Insects in a broad sense are equivalent to Hexapoda, and hexapods are often the rank of superclass. That is to say, in the generalized insect order, in addition to the above 29 orders, there are also 3 orders of the outer jaw mouth type (Ectognatha):
(1) Bullet tail order (Collembola);
Figure 29. Springtail (springtail)
(2) Protoceryl order (Protura);
Figure 30. Protozoa (proturan, conehead)
(3) Diplura.

In fact, in entomological textbooks around the world, as well as in the research and application of entomology, people are still using the generalized insect classification system.
The discipline that studies insect taxonomy is called systematic entomology. In insects, disciplines that specialize in the taxonomy of a particular order or taxon also have corresponding terms, such as systematic dipterology and systematic coleopterology.
