Cuticular hydrocarbons (CHCs) are present on an insect’s cuticle and plays very important role in the identification of forensically important insect species. The quantity and types of CHCs vary from species to species. This tool is increasingly used for species delimitation in addition to available morphological and genetic methods of identification. The main aim of this review is to elucidate the potential of this marker in species identification and use of CHC profile to address as taxonomic problems.
