Se presenta información sobre la composición de especies de coleópteros asociados a cadáveres de reptil (Iguana iguana Linnaeus, 1758), de mamífero (Rattus norvegicus albinus Berkenhout, 1769) y de ave (Columbia livia Gmelin, 1789), en bosque de pino perturbado (BP) y una zona de cultivo de maíz (ZC) en Zapopan, Jalisco, México. Los sitios se encuentran ubicados a 1668 y 1660 m snm de altitud respectivamente. Se colectaron 1,033 individuos; 787 en BP y 246 en ZC. En total se contabilizaron 59 morfoespecies, 26 compartidas, 14 exclusivas en BP y 19 en ZC; 18/20 en reptil, 28/28 en ave y 19/23 en mamífero respectivamente. Los coleópteros se agruparon como: necrobios (necrófagos), necrofilos (depredadores, copronecrófagos y saprófagos) y necroxenos (fitófagos), siendo los necrófilos depredadores el gremio más rico en especies y abundancia. La familia Leiodidae, seguida de Scarabaeidae fueron las más abundantes. Tomando en cuenta las abundancias existen diferencias significativas entre ambos sitios y entre cadáveres, sin embargo, las diferencias no son significativas en cuanto a la riqueza. ZC fue la más diversa; el cadáver de reptil en ZC fue el que presentó el mayor índice de diversidad, mientras que en BP fue el ave.
