Results from a dietary analysis of eight grasshopper species inhabiting a shrub-steppe community in southeastern Washington showed that 15 vascular plant species served as food items. Several plant species occurred at higher frequencies in the diet samples than in the plant community. Big sagebrush (Artemisia tridentata) was the most frequently selected plant species, followed by turpentine cymopterus (Cymopterus terebinthinus), green rabbitbrush (Chrysothammus viscidiflorus), and Carey's balsamroot (Balsamorhiza careyana).
