Teratodes monticollis, commonly known as the hooded grasshopper, is a species of grasshopper native to India and Sri Lanka. It was first described by the English zoologist George Robert Gray in 1832 as Gryllus monticollis. It is the type species of the genus Teratodes, which was established by the French entomologist Gaspard Auguste Brullé in 1835. Hooded grasshoppers feed on tree leaves, and they can become serious pests of teak and sandalwood.
