Insects are the numerous life forms that have captured the attention of human beings since ancient times. In the same context, proper classification and identification of life forms has been a challenge, and a plausible method of classification was established by Carlous Linnaeus, a Swedish botanist who published Systema Naturae in 1758. However, the Linnaeus system of classification was not based on evolutionary relationships among the target groups. Later, Darwin’s “The Origin of Species” in 1859 changed the way life forms were classified, where the identification, description and explanation of the diversity of the organisms had come to be known as systematics. According to Mayr and Ashlock (1991), systematics is the scientific study of the kinds and diversity of organisms, and any and all relationships among them; taxonomy, on the other hand, was the theory and practice of the classification of organisms. It took 200 years for taxonomists to describe the 1.7 million species on the earth, which is only 10 % of the total number of species estimated. In this context, identification of insects has been a monumental task which calls for the availability of more specialists and funding. But with the dwindling interest in taxonomy and fund availability, the classification and identification of various life forms, particularly insects, has been a major challenge to the scientific community. With the advent of molecular biology and molecular tools, the identification of life forms, including insects, has become quick, precise and easy. The development of species-specific markers enables even a non-specialist to identify insects to the species level.
