This curious insect belongs to the group of trehoppers belonging to family Membracidae. It is also called thorn Mimic treehopper as it looks like a thorn. most treehoppers are considered as pest, but some like Leptocentrus taurus was found feeding on the noxious weed Parthenium hysterophorus in Karnataka, India, thus acting as potential biological control agents. I found this Leptocentrus species on a Smooth rattlepod (Crotalaria pallida)plant.
