Skeletonizer

A fingernail-sized moth is capable of planting the seeds of destruction over acres of wine on the vine.  The offspring of the skeletonizer moth are legions of tiny yellow and black banded caterpillars that march across grape leaves, leaving only off-white bones of the leaves behind them.  They come for mine every year, so it's time to spray on a round of even tinier bugs that make the baby bugs sick.  Nature against nature.
