A planthopper is any insect in the infraorder Fulgoromorpha within the Hemiptera. The name comes from their remarkable resemblance to leaves and other plants of their environment and from the fact that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, these planthoppers generally walk very slowly so as not to attract attention.

related to the leafhoppers and spittlebugs but rarely damages cultivated plants
