Diversity of hopper species (suborder Auchenorryncha) in coffee (Coffea arabica) plantations with no shade (C) was compared with the diversity in plantations with shade of either poró (Erythrina poeppigiana)(CP) or poró plus laurel (Cordia alliodora)(CPL) in Turrialba, Costa Rica. Species-abundance and rarefaction curves were plotted for each system, and indices of diversity (Shannon-Wiener), dominance (Simpson), species evenness, and similarity (Jaccard) were calculated. The majority of hopper species and
