Some insect taxonomists organize the insects differently, using evolutionary links instead of physical traits. To identify an insect, you have to use the system of 29 orders. You can start with the physical similarities and differences between insects you observe.

An Insect species may occur in many regions and may have different common names in other languages and cultures. The scientific name is a standard name that used by the entomologists across worldwide. The two names using by this system: Genus and Species is called Binomial nomenclature.
