Massas fecais semi-frescas a quase secas foram coletadas semanalmente, em uma pastagem de Brachiaria decumbens Stapf, de maio de 1990 a abril de 1992. Estas fezes foram colocadas em baldes plásticos opacos (15 l), apresentando uma saída lateral e uma outra no topo, contendo frascos para a coleta dos besouros coprófagos adultos presentes nas massas. Foram coletados 18.844 exemplares da família Scarabaeidae, pertencentes a 37 espécies, dos seguintes gêneros: Ataenius, Aphodius, Agamopus, Pedaridium, Trichillum, Eurysternus, Dichotomius, Ontherus, Ateuchus, Sulcophanaeus, Gromphas, Digitonthophagus, Onthophagus e Canthon. Das espécies coletadas, 57% apresentam comportamento endocoprídeo, 35% paracoprídeo e, 8% telecoprídeo. Onthophagus hirculus (Mannerheim), Aphodius nigrita (Fabr.) e Ataenius sp.1 (Harold), foram as espécies mais freqüentes, constantes e abundantes.
