In the present study we collected and identified the seven species of grasshoppers belonging to subfamily Oedipodinae, Calliptaminae and Acridinae. Six species (86%) were found on loose sandy soil having xerophytic vegetation, whereas only one species (14%) was found on clay- loamy soil with succulent vegetation. Six parameters viz. Length of body, tegmen, hind femur, hind tibia, hind tarsus and number of hind tibial spines of the species Locusta migratoria migratoris were compared to know the morphometric variations at various elevations i.e. 2439 m, 3048 m and 3658 m from sea level. In the study of intra-specific variation in Locusta migratoria migratoris, it was found that at higher elevation hind femur has significantly increased while hind tarsus has decreased in male. In female, length of body, hind tibia and tarsus have decreased significantly at maximum elevation.
