Have you seen this pest? Where?

The black-dotted brown moth has been making itself known in parts of NC (also GA and SC).  Rarely noted as a significant problem, the presence of the leaf-eating caterpillars of the moth seems to be most obvious where pieces of bark on white oak have been removed and lie scattered at the base of the trees.  It isn't the caterpillars doing this but the birds and squirrels feeding on the caterpillars.  It isn't know to be a serous concern any more than any defoliator is, where multiple years of infestation can stress trees.  Here are a couple of links and photos about this pest...
