The present investigation was directed to study the diversity The study resulted in the enumeration of 40 species of short-horned of Caelifera from regions of the Western Ghats from Kolhapur grasshoppers belonging to four families of suborder: Caelifera. The districts including protected areas. Three major protected areas family Acrididae was dominant (27 species) followed by Tetrigidae fall under the study area viz. Radhanagari Wildlife Sanctuary, (eight species), Pyrgomorphidae (four species) and Chorotypidae Amba Reserve Forest and Chandoli National Park which is (one species). The report of 40 species from the forest habitat of the spread along the hilly terrain of the Sahyadri ranges of study region highlights the significance of the Western Ghats.

I. INTRODUCTION UB-ORDER Caelifera is a group of short-horned II. MATERIAL AND METHODS Sgrasshoppers of the order Orthoptera. This group was The extensive surveys were made from fields of Western previously rather fairly known from Maharashtra because the Ghats regions of Kolhapur districts during 2013 to 2016. The majority of Caelifera is diurnal and some of them are sampling of short-horned insects was done by standard insect nocturnal insects. The suborder Caelifera classified into four collection methods at day time, mostly, along with some time families under viz. Acrididae, Chorotypidae, Pyrgomorphidae at evening. The short-horned grasshoppers are terrestrial and Tetrigidae. A capacious literature was available for insects habitual to live in grasses, dwarf vegetations, bushes Orthopteran studies from India.

Some Whereas from Maharashtra 143 species of Orthoptera belongs species were also collected at the light source.
