AbstractExamination of crop contents of three species of grasshoppers in outbreak densities on desert grassland of eastern Arizona revealed that all three were ingesting a mixed diet of plants. Crops of nymphal and adult Aulocara elliotti (Thomas) contained an average of 67 and 93% dry weight of grass, respectively, placing this species in both the mixed graminivorous and the graminivorous categories. The preferred host plant of A. elliotti was Bouteloua gracilis (H.B.K.) Lag. but it was not an essential item, as a large population developed in a site where this grass was virtually lacking but other perennial grasses were present. Crops of nymphs and adults of both Melanoplus sanguinipes (Fabricius) and M. cuneatus Scudder contained chiefly forbs (88–100% of dry weight). The principal host plants were Erodium cicutarium (L.) L’Hér., Lupinus brevicaulis Wats., Microsteris gracilis (Hook.) Greene, and Plantago purshii Roem. & Schult. Both species of Melanoplus fit into the forbivorous category and evidence indicated they were in competition with each other for food. All three grasshopper species showed preferences for particular plant species and as a consequence had significantly different frequencies of plant taxa in their crop contents from what were present in the field.
