This regular production of genetically identical young makes armadillos valuable to medical researchers. I heard that armadillos will dig up and eat dead bodies. This unfortunate rumor comes from the armadillo's inclination to dig where the dirt is soft, such as a freshly-filled grave. They aren't after anything more than the insects in the dirt. Farmers have blamed armadillos for ruining melon crops, among other things.
Raccoons are probably the biggest culprits.
When farmers come out in the mornings, the slow-moving armadillos are seen taking advantage of the raccoon's leftovers, so they get the blame for ruining the crop. Some people have accused them of doing so, but it probably isn't a very likely scenario. Game hunters have suggested that the decline in population of ground-nesting birds is related to armadillo predation. Although armadillos will eat carrion, such as dead birds, they don't appear to actively hunt for eggs or chicks.
