Abstract
Thirty seven species of locusts and grasshoppers representing 26 genera, four tribes and 12 subfamilies belonging to the families Pyrgomorphidae, Catantopidae and Acrididae are reported from different localities of Bihar. Their distinguishing characters and bio-ecological data are provided along with keys to tribes and subfamilies. This paper comprising of distribution and field observation along with taxonomy of Acridoid fauna is the first of its kind from the state.

Summary
Acridoidea is one of the most sought after superfamilies of the order Orthoptera. The order Orthoptera consists of insects with paurometabolous or incomplete metamorphosis, including grasshoppers, crickets and locusts. The soil is mainly young loam rejuvenated every year by constant deposition of silt, clay and sand brought by different streams It is mainly drained by the Ganga River, including its northern tributaries Gandak and Kosi that regularly flood parts of the Bihar plains. The natural vegetation of Bihar is moist deciduous forests These forests are mostly found in the northern and southern parts of the state. Wheat and maize are the major crops During the survey it was concluded (based on field observation) that at an average, agricultural fields of paddy and wheat have shown maximum infestation of Aiolopus sp. If we talk about the field observation it may be concluded that the majority of the areas of southern and southwestern Bihar had more infestation as compared to the northern and northeastern regions of the state.
