Grasshoppers are widely distributed in all ecosystems. Tettigoniidae is a family of grasshoppers including katydids or bush crickets in the order Orthoptera. Approximately 6,400 species of Tettigoniids are found around the world. Conocephalus dorsalis, Tettigoniidae family, was collected from rice fields of Northern Kerala. It is an omnivorous insect that feeds grasses, seeds and small insects including pests. They are predators on rice field, controlling pest populations. The present study deals with species identification and revealed phylogenetic history of C. dorsalis using cytochrome oxidase subunit I (COI) gene encoded as mitochondria. The COI gene of C. dorsalis, 589bp are sequenced and obtained was deposited in the NCBI GenBank.
