Samples collected were sorted out to yield 34 grasshopper species belonging to 25 genera, 2 families, 10 subfamilies and 19 tribes. Maximum number of grasshoppers collected belongs to subfamily Oedipodinae (9 species) followed by Oxyinae (4 species), Acridinae (4 species), Gomphocerinae (3 species), Catantopinae (3 species), Cyrtacanthacridinae (3 species), Pyrgomorphinae (3 species), Tropidopolinae (2 species), Hemiacridinae (2 species) with least number in case of Spathosterninae (1 species).
