Nymphs feed on various grasses (including centipedegrass, bermudagrass and corn) from within foam (consisting of their own spittle) produced from juices of their host plant.^[2] Adults feed on the leaves of both native and introduced species of holly, as well as on the leaves of the eastern redbud tree. It is a pest of forage grasses and turf grasses such as those grown for lawns and its consumption of these plants causes economic damage throughout the southeastern United States.^[5]

Since 2016, P. bicincta has been associated with dying patches of pasture on the island of Hawaiʻi. By 2022, the distribution of the infestation had expanded, reached more than 70,000 ha and had caused serious, widespread and long-term damage to large areas of rangelands and pastures on the island.^[4]
