Melanocanthon nigricornis was observed to break up, bundle up, roll away, and bury pieces of the cap of a gill mushroom growing in sandy prairie in Wisconsin. These beetles were also found on a dead lizard and one was observed to roll and bury mammalian carrion. This is the first report of any species in Melanocanthon rolling and burying pieces of fungus and carrion.
