Abstract: Based on our investigation and relevant references,a total of 107 species of grasshopper,belonging to 7 families and 39 genera,was recorded in 8 sampling sites of Northeast China.The analysis of grasshopper community structure,faunal composition,and geographical distribution suggested that Palaearctic species were dominant in Northeast China,occupying 87.85% of the total.In the 8 types of habitats,Changbai Mountain had the most abundant faunal composition of grasshopper,whereas Xianghai Natural Reserve had the least one.Compared to other habitats,Xianghai Natural Reserve had a lower similarity index.
