ABSTRACT. Abracris dilecla Walker, 1870 (Olthoptera, Acrididae, Ommatolampinae) ate leafs of at least 14 plant species, in the families Asteraceae, Lamiaceae, Malvales (Sterculiaceae, Tiliaceae Dr Malvaceae), Poaceae, Fabaceae, Verbenaceae, Aristolochiaceae, Rubiaceae and Melastomataceae. Elephal1tapus lI1011is H.B.K. (Asteraceae) and Hyptis suaveolens Poit. (Lamiaceae) comprised 50% ofthe diet. The diet breadth of A. dilecta was compared to that of other II grasshopper species ofthe same sub-family, with rarefaction curves. The number of plant species eaten by A. dilecla was greater than that 01' nine olheI' grasshopper species of the same sub-family (Rhachicreagra spp.) but was lower then two others (Microptylopteryx hebardi Rehn, 1905 and Rhachicreagra astytophallus Jago & Rowell, 1981). This results are discussed in view ofthe broad geographical range and possession ofdeveloped wings by A. dilecta, which contrasts with mos! Ommatolampinae grasshoppers.
