Association of Oxelytrum cayennense (Silphidae, Coleoptera) with Pig Carcasses (Sus scrofa, Suidae) in Terra Firme Areas in Manaus, Amazonas, Brazil

Colonization aspects of the carrion beetle Oxelytrum cayennense (Sturm) in man-size pig carcasses (~60 kg) are presented at Adolpho Ducke Forest Reserve, Manaus, Brazil. This species colonized pig carcasses from bloated to skeletonized stages. Adults were eventually observed preying on fly larvae fr...
