Abstract
Western wheat grass, Agropyron smithii, was the plant most frequently ingested by Phoetaliotes nebrascensis (Thomas) in 4 of 5 habitats and was preferred in all. All grasses were eaten to some extent; nonpreferred plants may support populations in otherwise suitable habitats. Most forbs were unattractive but all tested species of Cichoriaceae were acceptable. Plant-finding was by random searching; selection was made only after contact through the mouthparts. While habitats in which preferred hosts were more abundant had higher grasshopper populations, annual changes in grasshopper abundance within a habitat were independent of abundance of primary food plants.
