Abstract
Microscopic examination of crop contents was used to determine the diet dry-weight composition and food preferences of adults of Aeropedellus clavatus (Thomas), Xanthippus corallipes Haldeman, and Circotettix rabula Relm & Hebard from a ponderosa pine bunch-grass community in northern Colorado. Grasses and sedges comprised about 97% of the diet of A. clavatus. Grasses and grasslikes comprised about 86% of the diet of X. corallipes while forbs supplied about 12%. The diet of C. rabula consisted of about 80% forbs and 14% grasses or sedges. A seasonal change in the diet and food preference occurred during the adult instar of the species studied. Insect parts and fungi were common minor constituents in the grasshopper diets.
