Carrion-associated mites often disperse between animal carcasses using phoresy, the transport of one species by another. The next generation of pre-adult mites disperses on the beetle parents at the end of the breeding event. The carrion beetle pays a huge cost carrying the mites around wherever it goes, because they are heavy and affect its ability to move and fly. Also, by competing with fly maggots, burying beetles help control … There are many carrion beetles in most parts of the world that are part of the successional carrion fauna that feeds on carcasses.
